Connection of aluminum radiators with polypropylene pipes

The effectiveness of our heating systems plays a critical role in keeping our homes warm and comfortable. The connection between pipes and radiators is one important component of this, as it helps to ensure that heat is distributed evenly throughout the house. This post will explain how to connect aluminum radiators to polypropylene pipes, discuss the reasons behind homeowners’ preference for this setup, and discuss how it can result in a more effective heating system.

Aluminum radiators are becoming more and more popular because of their exceptional heat conduction qualities, lightweight design, and longevity. Aluminum radiators, in contrast to conventional cast iron radiators, heat up quickly and react to temperature changes quickly, giving the heating system more control. In contrast, polypropylene pipes are becoming more and more popular for plumbing installations because of their affordability, flexibility, and ability to withstand corrosion. Polypropylene pipes and aluminum radiators work together to create a dependable and effective heating system that can handle the needs of contemporary homes.

The simplicity of installation is one of the main benefits of using polypropylene pipes to connect aluminum radiators. Polypropylene pipes are lightweight and flexible, which makes them easier to handle and connect to radiators in confined spaces than some other piping materials. Due to the lack of specialized tools and labor-intensive procedures, this ease of installation can save money and time when building or renovating a heating system.

Additionally, the possibility of leaks or inefficiencies in the heating system is reduced because aluminum radiators and polypropylene pipes work well together to create a tight, dependable seal. Compression fittings or push-fit connectors make it simple to join polypropylene pipes to aluminum radiators, creating a tight, watertight joint that is resistant to the pressure and temperature changes common to heating systems.

The ability of polypropylene pipes to withstand corrosion and chemical deterioration makes them an excellent choice when paired with aluminum radiators. Polypropylene pipes are resilient and unaffected by moisture and chemicals found in the heating system, in contrast to metal pipes that can corrode over time. This guarantees a longer lifespan for the heating system and lowers the eventual need for upkeep or repairs.

In conclusion, installing polypropylene pipes in conjunction with aluminum radiators can help homeowners improve the dependability and efficiency of their heating systems in a number of ways. This combination offers a workable and affordable way to achieve the best possible warmth and comfort in the house, thanks to its resistance to corrosion and ease of installation.

Step	Description
1	Prepare the necessary tools and materials: polypropylene pipes, aluminum radiator, pipe cutter, pipe inserts, and compression fittings.
2	Turn off the water supply to the heating system.
3	Measure and cut the polypropylene pipes to the required length using a pipe cutter.
4	Insert pipe inserts into the ends of the cut pipes to maintain their shape and prevent collapse.
5	Connect the polypropylene pipes to the aluminum radiator using compression fittings. Ensure a tight and secure connection.
6	Repeat the process for each section of the radiator that needs to be connected.
7	Once all connections are made, turn on the water supply and check for any leaks.

Connecting radiator

There are four radiator plugs on the sectional radiator, and each one could potentially be linked to the eyeliner. In reality, two strokes—supplies and reverse—are sufficient to move coolant throughout the battery. Three circuits are used to connect heating devices.

Connection	Description	Peculiarities
One -sided	For connection with the eyeliners, the upper and lower traffic jams on one side are used	Connecting is convenient in terms of the compactness of the placement of the plates. However, only the first 5-8 sections are effectively warmed up. The last sections are noticeably colder and quickly, requiring periodic flushing
Diagonal	The upper radiator plug on one side and the lower on the other are used	All sections are warmed up evenly. The heat transfer is maximum. Only the bottom of the extreme sections from the side of the dull lower cork is
Lower	Both lower traffic jams are used	Heat transfer is 10-12% lower than with a diagonal connection. Flushing is not required; sections are not shed in principle

What to pay attention to

To ensure that the heating system is created in accordance with the developed project, we advise you to choose the register types and configuration in advance.

Together with them, it ought to contain:

• boiler;
• pipelines;
• locking and regulatory reinforcement;
• pump (if necessary).

Installing heating equipment is not a particularly tough process:

• Choose a place in advance to heating devices according to the project;
• Bring a pipeline or pipelines to them;
• Combine the battery and trunk pipes with your own hands.

Radiator strapping heating is dependent upon the project that is created.

Connection of polypropylene pipes

We’ll talk about the procedure below, which involves using PP pipes—which are currently among the least expensive—to connect heating appliances to the heating system.

Binding with "Leningradka" as assistance.

Right now, there are two methods:

• does not allow you to adjust the register temperature (you can fix the use of expensive equipment);
• Most of the heat accumulates on the upper floors, at the same time the lower ones do not receive it;
• During the repair work, the instruction requires to turn off the entire riser;
• It is very difficult to disconnect from the central heating system.

1. Two pipes are used:

• First – supplies hot water to the batteries;
• second (return) – diverts it from heating devices.

1. In this case, a parallel connection of batteries is made.
2. Use it for heating private houses, apartments with an autonomous heating system.
3. Advantage:

• allows you to adjust the temperature of each heating device;
• The register can be disconnected from the system without turning off the entire riser.

Diagram of the heating radiator’s two-pipe cutting

The following components are found in both systems:

• heating batteries that have an air discharge valve at the top and a plug below. With the lower connection method, the latter is installed on top;
• radiator passage;
• thermostat and valve for the 2-pipe system;
• shank;
• locking crane;
• Rachagi with which the coupling and registers is fastened;
• bypass for the 2-pipe system;
• Polypropylene, polyethylene, metal -plastic or metal pipelines.

Different options for binding

Ways to connect radiators

Three primary categories of connections exist:

1. The side one -sided is considered the most acceptable. The feed is made in the upper cork, the return is connected to the lower. The method is able to give maximum heat transfer, which provides the greatest efficiency.

Advice: Avoid connecting the feed from below as this will result in an 8% reduction in system power.

1. Diagonal is sometimes used in batteries that have a fairly large length. In this case, heating occurs evenly all sections of the equipment, without creating temperature changes, which is reflected in their effectiveness. The feed is connected to the upper passage traffic on one side of the product, the return to the lower side.

The heating system may lose up to 10% of its power if hot coolant is brought in from below.

The technique of strapping heating devices from below

1. Nizhny is recommended only when installing pipelines in the floor. In this case, power loss will also be up to 10%.

Install radiators beneath windows rather than on their sides, as a helpful tip. Pay attention to the height differences and the indent from the wall and windowsill.

Types of radiators

It is advised to use new heating equipment when installing a new heating system. There are numerous options available on the market today for registers constructed of steel, aluminum, cast iron, or a combination of metals.

Just select the best model available. This could be:

1. Steel continuous and thin panel, which is possible only from below or from the side.
2. Sectional lightweight from aluminum or bimetallic. Such batteries are connected in all three ways for which polypropylene pipes are ideal.

How to attach the batteries in a sideways manner

For apartments with central heating, we advise swapping out heavy cast-iron batteries with bimetallic ones. They can withstand the addition of alkali to the coolant better and have a large heat transfer. Steel or aluminum radiators work best for self-sufficient heating in apartments and private homes because the pressure in these systems is low.

Connection of radiators

Connection scheme

Draw a system diagram before attaching the heating radiator to the polypropylene pipe. Please keep in mind that there are multiple ways to connect batteries:

Connection method	Peculiarities
One -pipe	This system is the simplest and most economical in terms of consumption of materials. However, it is suitable only for small rooms, since the coolant along the way to the last battery heats intermediate, which leads to their uneven heating.
Two pipe	It is also a sequential connection, however, hot coolant and “return” flow through different pipelines. Due to this, the heating of the batteries is carried out more evenly.
Collector (Distributive comb)	This method is the most effective, but at the same time the most costly. Its principle is based on a parallel connection of all radiators through the collector.

Diagram showing the connections between the collector and the heating batteries

The type of scheme chosen is determined by the housing’s attributes, such as its area and number of units.After selecting the system type, you should physically draw on the plan where the room’s batteries, fixtures, and other components are located.

The existence of such a plan will determine the quantity of materials needed and facilitate additional system installation work.

Assembly of the pipeline

Thus, the following are the instructions for assembling the pipeline:

• First of all, you need to cut pipes according to the size indicated in the diagram.
• Further cut the ends of the prepared segments must be cleaned from burrs.
• Then the ends of the segments must be cleaned with a special device operating on the principle of sharpening for pencils. This operation is necessary for further soldering.
• After that, pipes and fittings are heated in a special soldering iron, after which they are cooked.
• Further, the pipeline is mounted to the walls using special holders.

Counseling! Prior to beginning pipeline assembly, if this is your first experience working with plastic pipes, you should receive trimming training.

A welding machine with nozzles is seen in the picture.

As a result, the pipeline is put together as a designer.

In this instance, it is necessary to adhere to the following guidelines when using the welding machine:

• Before the welding, the device must be heated until disconnected, and then wait for the re -turn on.
• It is necessary to strictly observe the heating time of the connected parts. For different types of solderingrs, it can be different. Therefore, before using the device, you should familiarize yourself with the table, which is usually available in the instructions.
• You need to connect the parts evenly, avoiding distortions.
• After connecting the parts, they cannot be shifted and moved until polypropylene freezes.

The polypropylene heat pipeline’s component pieces are generally fairly easy to weld.

Putting a mark on the wall

Installation of radiators

It must be installed before the heating radiator can be connected to the polypropylene pipe.

This work is completed in the following order:

1. First of all, you need to mark the location of the batteries.

The following SNiP requirements need to be considered in this situation:

• the distance from the wall should be at least 2 cm;
• The distance from the floor should be about 10-15 cm;

1. Then the installation of brackets is performed. In this case, it is necessary to use the building level so that the device is located exactly. For fastening brackets, you can use the dowel-clavings.

Verifying the brackets’ placement in relation to the building level

1. After installing the brackets, you need to hang a radiator on them.

Every radiator in the space needs to be installed on such a system.

Battery connection

The following procedure is followed when attaching the radiator to the polypropylene pipe:

• First of all, the transition coupling is attached to the battery. It should be noted that the connection of aluminum radiators with polypropylene pipes is carried out by special couplings that differ from adapters intended for cast -iron batteries.

The radiator’s connection to the pipeline via the adapter

• Then a ball valve, adjusting valve or radiator valve are connected to the adapter.
• Then the crane is connected to the polypropylene heat pipeline.
• According to the same scheme, the radiator exit to the pipeline is connected.

Possibly all of the major connections between the heating batteries and the polypropylene pipeline are located here.

Connecting pipes and radiator to the system

• Pipe cutting with a diameter of 32 mm. The cut should be made very even in places in which the installation of parts of the binding will be carried out suitable for the radiator.
• Assembly of part of the strapping, suitable for the battery placed at the top of the fitting. This part consists of a tee, a tube with a diameter of 20 mm and angle. These three parts must be soldered. To do this, one end of the tee and one end of one of the pipes is inserted into a soldering iron and heated. Next, the heated ends are applied and waiting a little. Soldering one seam lasts no more than 3 minutes. Similarly, they solder the other end of the tube and angle.
• Assembly of the second part of the strapping. It will approach the tocerator placed below the radiator. The peculiarity of this part – it should go around the pipe by 32 mm, which is above. This part is soldered from the tee, a piece of pipe for 20 mm, three adapters with a rotation angle of 60 ° (there are necessarily pipe with a diameter of 20 mm between them), a piece of pipe 20 cm and an angle of 20 x 1/2rd. The length of the pieces of pipes depends on the features of the developed scheme. During the soldering of the tube and adapters, you need to immediately put in the correct position. This is because when making an error, the soldered parts cannot be disconnected.
• Soldering two tees 32x20x32 mm (they are placed at the end of the soldered parts of the strapping) and pipes with a diameter of 32 mm. Each end of the tee is soldered with the cut end of the pipe.

• Joining shut -off valves to two parts of the strapping. First, it is disassembled, or rather, unscrewed a pipe with a pitch nut. Further, the main part is screwed to a metal fitting located at the end of the angle of 20 x 1/2nr. It is simply impossible to screw. Light is wound on the fitting thread and after the installation of shut -off valves is carried out.
• Screwing a pipe with a rug nut into the foot Or a radiator fitting.
• Installation of shut -off valves in the pipe and fixation by tightening the united nut. For the last process, a plumbing key is used. During this stage, flax or other sealing is not required to wrap it on a pipe.

Copper Fitings installation features

The building materials market also provides an extensive assortment of copper pipelines and associated information. This gives the masters more freedom and permits installation work of varying complexity.

Copper pipe fittings have the following benefits:

Fittings made of steel and copper

• Weigh little;
• resistant to high temperatures;
• not deformed under the influence of sunlight.

In order to construct the highway, the master’s connecting elements are utilized. This includes creating the necessary number of branches, bends, and new angles and turns.

There is a good selection of copper heating fittings available, allowing one to choose precisely what is needed in each unique circumstance. For instance, a wide range of fittings for installing pipelines of various sizes are available on the windows. Particularly well-liked are basic components like doubles, couplings, crosses, corners, and so forth.

Features of the strapping in the 1- and 2-pipe systems

A single pipe system

1. Pipes that are attached to the introductory and output fitting are always connected to the same vertical riser or horizontal pipe placed around the perimeter of one -story house. If a vertical pipe is created for supplying the coolant, then one end is trained in the upper fittings of the battery, and the other in the lower.
2. Always carry out the installation of bypas. It is a tube that connects two pipes suitable to the introductory and output of the battery. During normal operation, the bypass is not needed. However, in the case of repairing the heating device and the overlapping of shut -off valves, the coolant fluits on bypass, that is, the system works without stops.

1. The strapping in this case is performed so that two batteries are connected to different pipes. The pipe is connected to one that supplies the heated liquid, to the other – the tube that removes the cooled coolant.
2. Provide for the use of a larger number of tees and connecting elements necessary to bypass one pipe of the other. The latter are in demand because two pipes often intersect.
3. Baypas installation does not need to be done.

Drivers and American

What it is

Let’s begin with a brief historical digression.

By historical standards, just three types of heating devices were widely sold and used in our nation until relatively recently—roughly twenty to twenty-five years ago:

• Convectors, which are a coil of a steel pipe with traveled on it to increase heat transfer with steel plates.

Home design, cruel and meaningless.

To be clear, they may have included blinds to control heat transfer and a decorative screen in their design.

• Plastic radiators – two stamped steel plates welded around the perimeter. The coolant moved along the labyrinth of the grooves between them.
• Cast iron sectional radiators. They, I think, do not need to be presented, since they are now installed in most apartments.

There were just two ways to secure it:

1. Welding. Exclusively the convector were welded to the eyeliners: their mechanical strength and service life, at least not inferior to the duration of the operation of risers and carts, did not assume dismantling or replacement.
2. Drills. A coupling (in the case of a convector or a plate device) or a radiator plug (in the case of a sectional radiator) was driven along a long thread on the eyeliner, while stupefied on the device’s thread or screwing into it. Then the connection was sealed.

The initial aluminum radiators were installed in drills, the antiquated method. But after a few years, Americans widely popularized basic fittings that included detachable connections with a rubber seal and rug nut. Their primary benefit was the device’s easy and quick disassembly, which took only a minute and required little effort compared to the previous half-hour-long process.

Modern fittings connect the aluminum heating device.

Help: Gas key number 2 can be used to twist the cast iron radiator traffic jam from the new radiator. It must be extended using a lever or the key number 4 in order to deal with the previous clouded traffic congestion. Simultaneously, the cork frequently breaks in half, losing threads instead of twisting.

Does the American have any flaws? Essentially, there is only one drawback: the density of the rubber seal and its seal quality determine how strong the connection can be. The seal and the relatively thin university nut of the American are the weak links when there is a lot of pressure in the circuit (like with a hydraulic jacket, for example).

Recommendations

Although they are fairly clear, the author’s own conclusions are likely to face opposition from numerous other experts.

• In central heating systems with a characteristic high probability of exceeding the standard pressure, it is better to use the usual threaded drives.

The drives in the SO system are connected to a cast iron radiator.

• It is advisable to use Americans in autonomous systems.

Properties and features

The material does have drawbacks in addition to the ones mentioned (see photo and circuit of the heating boiler with polypropylene strain).

Use polypropylene pipes. After familiarizing yourself with the material’s characteristics and the subtleties of its application in heating installation, you can.

The pipes can form the contour of any configuration because of the properties of the polymer. This will even enable a novice to plan and install a sophisticated pipeline.

Naturally, mistakes will occur because it requires a basic understanding of the foundations.

The owner should anticipate higher heat losses the longer and more intricate the pipelines are.

Simplify the contour configuration if at all possible; this is a necessary step. This will result in an increase in heating efficiency.

Special soldering equipment is used to connect polypropylene pipes.

Potential leaks are avoided because the molten material solidifies the coupling between the products. Compared to threaded joints, this method—soldering polypropylene pipes—is more practical.

Make superior pipes. There are two methods to make polypropylene: soldering and fittings.

A completely dependable connection that prevents leaks can be made with skillful use of the soldering equipment.

Employing less dependable fittings will, in certain cases, resolve the issues that have emerged.

Every node is examined from the perspective of how feasible it would be to use a particular technique.

FACT: Polymer will prolong the useful life of pipe products for many years without compromising their operational qualities.

The development of organic synthesis has made plastic pipes more resilient to temperature changes and pressure (see this article for information on a closed combustion gas storage water heater).

There are products that can be heated to 100 degrees and maintain pressure of up to 25 bar. In addition, linear dimensions (which show the polypropylene pipes’ expansion coefficient when reinforced with fiberglass) don’t change.

Recall that using polymer directly in the boiler is subject to limitations.

Hard mounting is used for the division and return, with either American or paronite gaskets burning in the metal.

By using this method, a strong connection will be made, preventing pipes from expanding or contracting when the temperature changes.

Only permits the use of Paklya and forbids the use of FUM tap.

Temperature changes will cause rubber gaskets to flow and disrupt the connection’s tightness.

Radiators must first undergo extensive verification before being connected to the circuit.

The installation of a closing reinforcement, which is mounted in the strapping created, is necessary for battery repairs or replacement.

Types of radiators

Cast-iron batteries have been replaced by ergonomic, aesthetically pleasing modern radiators when it comes to battery exposure. Any of the current species of radiators can be used for heating a private residence. Rather than the kind of battery, the decision is based on the material capabilities.

Manufacturers provide three varieties of contemporary radiators, the fourth being cast-iron:

1. Steel. There are tubular and sectional. Tubular are more expensive, since they are considered more attractive outwardly. The heat transfer is the same.
2. Aluminum. These products are more effective than steel in the heat transfer. Require a neutral reaction of the coolant. With an alkaline or acidic environment, they quickly become unusable.
3. Bimetallic. Combined batteries made of steel and aluminum. Combine all the positive moments of the first two types and are the most expensive.

Note: Polypropylene pipes can be connected to any kind of radiator.

Polypropylene pipes What fittings choose

Various construction stores. Because there is a wide variety of connecting elements with varying sizes, selecting the correct model is not as difficult. They are split into sections that are not carved and carved, which can be both solid and foldable.

Installing the heating radiator’s fixtures

Selecting the right kind of necessary element requires consideration of the tasks it will carry out. For instance, it is more convenient to use a whole fitting to connect the hose, but it is preferable to use a detachable threaded mount for the counter.

Considering the expansion caused by temperature is crucial when installing polypropylene pipes. When installing a radiator with a hot water supply, this is crucial.

It is for these reasons that the compensator is mounted. Its primary duties include stabilizing pressure surges in the heating system and absorbing temperature changes.

One system is made up of fittings pipe and polypropylene. As a result, the heating system in this instance uses polypropylene fittings.

In certain situations, joining metal pipelines becomes necessary, in which case a fitting with a brass threaded insert is used.

Heating in the house

Since the buildings must be ready for the chosen type of heating in advance, you should first choose the types of radiators and the options for connecting them. The multiple components that make up the modern heating system for the premises.

Among them are:

• radiators;
• pipelines;
• heating devices;
• boiler.

Soldering polypropylene wiring by hand without the need for a soldering iron

In our markets, a wide variety of options are available in bulk.

The following are the general guidelines for installing batteries:

• Choose the place first for their placement;
• bring the pipes to them;
• Connect them with each other;
• make a trial start, and, if everything is in order, turn on the heating at full power.

How to install polypropylene tribbs on heating radiators and use a jumper to quickly disconnect

Heating scheme

The entire strapping scheme is geared toward the heating boiler, which is the primary component in the heating system. There will be different types of strapping for different types of boilers. For instance, floor boilers should not be installed at the level of the highest heating system elements because they are ill-suited and will operate inefficiently, possibly to the point of breaking down entirely.

A cork that stops the coolant from naturally circulating in the system frequently forms in floor boilers when they are unable to evacuate air that has accumulated at the top of the system. Air vent pipes should be added to boilers without an integrated air discharge system in order to provide vertical venting.

The heating unit has built-in heating air vents, as indicated by the pipes in the lower section of the unit. Such a system is frequently found in wall boilers. It is important to keep this in mind and avoid adding unnecessary extras to the strapping.

Boilers without an expansion tank, pump, or some automation are available for purchase. This composition is intended for use in systems with natural circulation in boilers.

You can buy each of these parts separately.

The heating system’s design

It is more efficient to install the circulation pump in front of the boiler for the heating system, and the security group anywhere that there are no locking mechanisms between it and the boiler.

Less polypropylene pipes are needed in systems with natural circulation because the aforementioned components are not necessary for forced circulation systems.

Heating is the next action to take. essential to verify the system’s assembly quality.

The following video shows an example of binding radiators with polypropylene pipes and inspecting their quality.

Polypropylene pipe

Although a variety of pipes can be used for radiator strapping, experts advise using polypropylene. The most straightforward and affordable option is to purchase blinking taps for strapping made of polypropylene. These taps can be either straight or curved. Brass reinforcement costs more and requires more work to install.

This is how polypropylene strapping is done:

• The coupling with a rug nut is inserted into the multiflex, which is easily connected to any output;
• The pipes themselves are attached to the walls at a convenient height, they should not fit tightly to the surface, it is better to leave a gap of 2-3 cm. The pipes are attached using special brackets, which are fixed to the wall with nails or self -tapping screws.

When installing pipes into the wall, a polypropylene strainer can also be used to reach the radiators; in this scenario, the pipes are only visible at the locations of connection.

Although a variety of pipes can be used for radiator strapping, experts advise using polypropylene.

Batteries can have the most varied fasteners; these are typically pin connections that are affixed to the wall’s surface. The radiators can be hung at the necessary height by using corner brackets as well. Fasteners for panel batteries are part of the kit; separate purchases are required for sectional batteries. Usually, two brackets or pins are sufficient for one section.

The cranes are connected in the following manner:

• The tap is disassembled, a fitting and a united nut are being screwed into the radiator;
• The nut is tightly twisted with a special key.

This is a very easy process, as you can see. Installing a crane is unlikely to occur without a special plumbing key that is only available to Americans.

To install batteries and complete their strapping, the following supplies and equipment are needed:

• set of special keys;
• seals for threaded connections;
• Pacli and threaded pasta;
• Threads for carving.

Features of connecting radiators

Certain features define heating installation:

1. It is necessary to observe the distance from the radiator to the window sill 100 mm. If the gap between the batteries and the bottom of the windowsill differs, then the heat flow is disturbed, the effect of the heating system will be low.
2. From the floor surface to the battery, the distance should be 120-150 mm, otherwise a sharp temperature difference occurs.
3. In order for the heat transfer of the equipment to be correct, the distance from the wall should be from 20 mm.

Simultaneously, we consider that the installation technique has a significant impact on the installation and efficiency of heating radiators: the heating system’s maximum efficiency under a windowsill is 96-77%; in a niche, it can reach 93%; in a partially closed form, it can reach 87-93%; and in a completely closed form, it can reach 75-78%.

There are several ways to install the heating radiator; metal, polyethylene, and polypropylene pipes are used for strapping.

When installing, it’s crucial to align the pipes and the batteries themselves correctly and to connect them in compliance with all standards and guidelines. In this scenario, the heating system will function flawlessly and won’t need any repairs.

The materials used

The parts that are being shown are intended to be used in a two-pipe circuit that has a horizontal branch supply beneath the battery.

Products with a 32 millimeter diameter are utilized (this page contains information about connecting ball, steel, and coupling cranes).

The following supplies are required (for a single radiator):

• tees for 32x20x32 millimeters – 2 pieces;
• pipe product with a diameter of 20 millimeters;
• angles size 20×1/2 external – 2 pieces.
  on the one hand, metal thread;
• adapters with a rotation angle of 60 degrees – 3 pieces;
• plumbing flax.

It also requires a tool:

• a soldering iron for polypropylene that can be rented;
• a saber -type saw or scissors on polypropylene;
• Divorce key.

They also offer a fitting of reinforcement, which can be a ball, shut-off, or valve (read here for information on fixing a ball crane with your hands).

Using polypropylene pipes is thought to be the greatest and most dependable option for heating systems, regardless of the wiring method selected.

Watch the video for a thorough explanation of how the heating batteries are connected to the polypropylene pipe system.

The choice of materials

The following are some of the benefits that polypropylene pipes have gained in popularity:

• The price of them is much lower than for metal analogues.
• High durability, due to the fact that plastic does not rust, besides, there is practically no precipitate on it.
• Do not need painting.

It is important to remember that not every kind of polypropylene pipe can be used with a heating system. The truth is that they need a layer of reinforcement to stop the pipeline from significantly expanding in temperature.

Polypropylene pipe with reinforcement

Furthermore, since fiberglass reinforcement causes the coolant to become saturated with oxygen, it is preferable that the reinforcing layer be made of aluminum. Boilers and other heat supply components’ metal surfaces rust as a result. Marquiting25 indicates pipes with aluminum reinforcement that are appropriate for heat supply systems.

Note: It is important to consider the consistency of wall thickness when selecting pipes. To accomplish this, you must examine their slice.

In terms of diameter, –25 mm is the ideal value.

Additionally, fittings must be purchased at this time. These fittings include:

• Couplings;
• Corner adapters;
• Ball Valves.

Diagram showing how radiators are connected to one and two pipes

The choice of radiators

Aluminum sectional radiators were traditionally paired with polypropylene.

Aluminum radiators that vary in the cart’s interface.

Why is this such an explicit instruction?

Which products are worse, steel, bimetallic, or cast iron?

• The price of aluminum radiators below. than any analogues, excluding only with your own hands from the steel pipes registers .
• Due to the highest thermal conductivity of aluminum, all the sections of the sections have the same temperature. which provides maximum heat transfer with minimal dimensions of the heating device.
• Overpayment for comparable thermal characteristics, the bimetallic radiator is meaningless. since the strength of any circuit is equal to the strength of its weaker link. In our case, a weak link will be polypropylene.

When aluminum radiators are connected to polypropylene pipes, it indicates that shut-off valves are installed in them. Which one, and why?

A pair of valves is the easiest and least expensive solution. Better: a ball; it never needs to be maintained, is incredibly dependable, and always keeps its tightness. Unlike screws and corks. The sole job the valves do is enable you to fully shut off the heating appliance so that it can be repaired or replaced if needed.

There are two ball valves on the battery.

The battery’s advanced option is to have one or more throttles installed.

For what purposes are they necessary?

• The throttle allows you to manually reduce the heat transfer of the device at high temperature in the room.
• A pair of throttles are used in cases where a two -pipe system requires not only adjustment, but also balancing – limitation of the flow through the closest to the boiler or pump radiators. For balancing, a throttle is usually used on a reverse eyeliner, to adjust the temperature in the room – on the supply.

The connection of the radiator with a polypropylene pipe using a thermostatic valve and thermal car is the last and most convenient option, albeit the priciest as well.

The thermostat restricts the amount of heat carriers available by closing the valve when the temperature rises (due to an increase in the linear size of the bellows in the thermogram body); when the temperature drops, the valve opens. This maintains the room’s temperature regardless of changes in the outside elements, such as the street’s weather or the coolant’s specifications.

The rising stream of warm air from the radiator or eyeliner should not be where the thermostat is located.

It should be noted that the thermostat in a two-pipe heating system frequently has a balancing throttle on the second eyeliner.

Apart from turning off and adjusting cranes, radiators have aerialists, or taps for air left over after the contour is discharged, during the lower connection.

Aerialists’ roles can include:

1. Cranes of Maevsky. Their advantages are compactness and cheapness.
2. Conventional valves or water -brutal cranes installed in the upper passage cork of the radiator. They are convenient for high throughput: through the valve, air is faster faster.
3. Automatic air vents removing air bubbles from the contour without the participation of the owner.

How does one connect a heating radiator to a polypropylene pipe and what fittings are needed?

• The insert into horizontal roslic is performed through the coupling tee with the transition of the diameter. A typical diameter of a rosllic in the contour of a reasonable length with forced circulation – 25 – 32 mm; The outer diameter of the eyeliner to a separate heating device is 20 mm.

Two welds are used to create the infusks in the roser.

• Adapters from a welded coupling on a 1/2 -inch thread allow you to connect valves, chokes or thermostatic valves.
• To combine locking reinforcement with radiator traffic jams, Americans are used – rapidly supporting fittings with firm nuts and rubber gaskets. They reduce the time of dismantling the radiator to 30 – 45 seconds.

A combined solution—a ball crane and an American—is seen in the picture.

Features of installation

The primary distinction in this instance is the polypropylene fittings, which can be readily soldered with a specialized soldering iron or screwed. Plastic has a low melting point, which makes this possible.

The serial number of the step	Action
1	Cut the pipe
2	Remove the chamfer
3	Put a mark to which melting is necessary
4	We insert a pipe and fitting into a soldering iron
5	After a few seconds we take out
6	Connect fragments and wait for their solidification

However, the installation of steel, aluminum, or cast-iron radiator fittings depends on the kind of installation that is specified in their design:

• Welded. Are made of stainless steel and connected by a strong sealed seam using welding. Cons: the difficulty of dismantling and the need for expensive equipment.

Stainless steel connecting components that are welded

• Under the ration. Can be made of copper or bronze. Fixed with a burner. Used exclusively for installing heating pipelines from steel.

Assortment of soldering connector parts

• Squeezing. Do not require expensive devices, all installation is carried out with an open key due to a special squeezing ring.

• Compression. Often used to connect plastic and metal pipes, as they can interact with any materials. But they are also not cheap.

Connecting product for compression

• Press-fiting. Guarantee an increased tightness of tightness due to the sealing ring inside the crest. But at the same time require the use of an expensive tool-press machines.

Expert apparatus for the installation of press films

• Self -fixed. Copper products allowing the connection of heating elements from any materials without using a special tool. They are removed as easily, as they are installed.

Connection of the heating radiator good -natured plumber

I wrote a post at the beginning of the site’s creation about how to replace the heating radiator on my own.

Many questions have been raised since then, and one of the most common ones is now the focus of this content.

Salutations for the afternoon! Kindly offer guidance. When radiators were replaced appropriately two years ago (I did not do this myself as I am a complete amateur in this field), the following occurred:

Everything was good, but I had accidentally poured an American radiator fluid into the next drain or flood caused by the heating risers ((. In response to the question of what to do, he called the plumbing, pulled on the American a little more tightly (which caused the flow to stop), and said that it would now flow periodically because the elastic band dries up when the temperature drops. But I’m not sure how to attach the taps to the bypas.

Could you please give me some advice on what to do next with this installation? And how can one act morally? If not, I’m terrified to try again, and in the second year it will happen again ((thank you!

It appears that I cannot deem polypropylene Americans trustworthy, and I do not advise sewing up any trim.It is important to begin by stating that I have totally removed the Turkish pipe of Pils from the materials I work with. In certain instances, an American did not just flow; in fact, one such American even came out of a nut. What I will not discuss regarding ecoplastics and Valtek.

Rewinding the bypass all the way will not be harmful in this particular instance. It isn’t very good. Because of the jumper’s excessively short pipe, the feed and the brother are "pulled" apart.

If the polypropylene bypass is soldered, the American can be completely excluded. This is what the plan is all about:

It’s not hard to save such a jumper in your situation without an American. Long enough to push and solder the pipes together.

What happens if the length prevents the jumper from using this method? The bends, for instance, are much shorter and cannot be unclenched.

Next, utilize an American conical.The absence of a gasket is the fundamental feature of the conical American. It has a precisely calibrated cone that doesn’t let water pass through when tightened with a cloak or nut. Connection to cheap, but reliable. If you tighten everything down, there won’t be any leaks.

Although it is generally preferable to locate the bypass as close to the battery as possible, the jumper can be installed right away on the bends if the distance between them and the radiator is less than half a meter. When it comes to polypropylene, an American is a necessity.

However, because such a pipe can be bent, the American is not included in your system of metal-plastic pipes.

Metal and plastic can occasionally be connected in this way:

However, I advise using the subsequent connection scheme:

Furthermore, it makes no difference if you collect illegal or pressfitting items.

In the second scheme, we stop the bounces to the radiator so that in the event that there is a current on the nut or on the press, the radiator can block completely.

We don’t cross over the jumper or go against the circulation in either scenario.

If you examine the first plan, you will require American-made cranes or thermostats; additionally, I advise selecting those without gaskets. Seek out a cone.

Individual Americans are required in the second scheme, and they need to be screwed into the heating radiator.

What in the end:

1. Cranes ought to pursue jumpers in order to maintain proper circulation. 2. Americans should not be used with gaskets. Apply a cone. 3. Make an effort to reduce the quantity of connective connections.

Stages of connecting heating radiators

You’ll need to add extra tools and parts for the battery installation inside the house and the connection that follows. Like the primary supplies, all shut-off valves ought to be made of polypropylene. These days, ball cranes come in both straight and curved variations.

As an example, brass reinforcement can be used, but it is more costly and interesting. Over time, the locations of brass reinforcement that have a coupling or a propylene pipe will become weaker.

Seals, a set of keys, threaded paste, mounting ribbon, and thread for making a thread are required to make the connection correctly.

The following is the strapping.

The device that the coupling is inserted into and has a pitch nut on it is called a multiflex. Any exits and inputs can interact with such a connection.

Polypropylene pipes are sized appropriately. A space of 20 to 30 centimeters is allowed between the wall and the roadway. The locations where the pipe is fastened to the wall are called special brackets.

The pipe is only visible on the surface where it connects to the radiators if you wish to conceal the pipes inside the wall.

Typically, pins are used to secure batteries to the wall. Batteries are suspended from corner brackets in certain instances. The number of sections in a sectional radiator determines the number of brackets needed.

Installation of a crane in the battery. A plastic crane is taken apart. Next, a rug nut is used to secure the fitting into the planting nest, and the nut is tightened. The crane’s plastic case is placed atop the fitting.

The supplied pipe is brought straight to the tap with the aid of bends, at which point the soldering iron comes into action. Use an 800W lobster set to 270 0 C for heating when working with polypropylene pipes. Setting the temperature more or less is not advised. The crane’s output is equipped with a heated coupling. When properly prepared, the entire process takes no more than five to ten minutes. Remember to install thermostatic regulators at connection points.

As a guide: The pipes that are brought to the radiator should be correctly positioned geometrically, free of tension and inclinations. If not, the intersection will experience continuous voltage, and the highway’s constructed slope will obstruct the system’s natural water circulation.

We recommend watching this video to get an idea of how the finishing work is done, which involves connecting pipes to the radiator.

Fitings are different

There are numerous kinds of heating fixtures available.

Taking into account the different types of compound elements based on their intended use is worthwhile.

They are separated into the subsequent categories:

• a coupling – a fitting resembling a barrel with a hole inside. It belongs to simple elements. They are necessary in order to connect the pipes of the same diameter in the straight section; Fitings for heating radiators
• adapters – type of fittings that have a different diameter at the ends. This means that they are used to connect pipes of different sections. This also includes drives and nipples;
• corners, bouncers – the elements of the connection necessary to create the desired angle of direction of the pipe.
• Tees, collectors are designed to combine several pipelines on the wiring. These elements have different diameters. It is possible to choose for heating – they are suitable for various pipelines, including for connecting heterogeneous pipes;
• Crosses are elements that are used in order to combine pipes of the same diameter at the joints where they branch.
• Backs – are the connecting elements that are necessary to connect a flexible hose to the pump.
• plugs – fittings that are used in order to ensure a tight sealing of the ends of the pipeline.

Place of radiators in the heating system

Nowadays, radiators are a major component of residential building heating systems. Due to design constraints, the majority of residential buildings—particularly apartments in multi-story buildings—cannot be equipped with intra-floor heating, necessitating the use of interstory plates that are noticeably thicker. Therefore, wall radiators—also known as batteries—do the majority of the work when it comes to heating interior living spaces.

Heat energy from the coolant is transferred to the surrounding area by radiators. The coolant’s temperature, the radiator’s manufacturing material’s thermal conductivity, and the heat transfer area all affect how much heat is transferred. Many technical advancements in modern radiator design enable you to connect them in the heating contours of nearly any wiring scheme.

Note: Modern cast-iron batteries are also outfitted with built-in air vents to prevent air traffic jams, whereas older models simply had nozzles for the supply and output of coolant.

If the heating device has an air plug, all that is needed to open the descent valve and let air in is for the system to function more easily and effectively thanks to the new battery design.

Water heating bimetallic radiator with expanded heat transfer area featuring walnut

The ability to select the best connection plan and install heating devices as logically and effectively as possible was made possible by the development of contemporary heating battery models. Despite the numerous benefits of polypropylene, the water heating contour’s longevity and efficiency rely on the binding’s quality, which sets the appropriate conditions for its use.

Crucial! Polypropylene pipes are connected to a metal riser using special adapters. A polymer polypropylene pipe is connected to the second end of the adapter by hot welding, and the metal connection has a threaded connection on the first end. When cutting the heating radiator into a polypropylene pipe circuit, matching couplings, adapters, and connecting fittings must be used.

Due to the high coefficient of thermal expansion of polypropylene pipes, spaces should be left between the ends of the pipeline sections and the wall when installing the heating circuit. This will prevent the pipe span from resting over the ends of the wall and becoming deformed due to linear elongation caused by the effects of hot coolant. It is important to remember that a pipeline will lengthen as its span increases.

Although adding fiberglass or aluminum reinforcement to polypropylene pipes lessens linear expansion, it does not entirely solve the issue. As a result, P-shaped or, if the location permits, spiral compensators must be installed on sections of considerable length.

Options for heating systems

An autonomous heating system gives you a choice between two options for the heating system’s device in a private home or a small cottage.

1. Single -circuit (single -pipe) – classic, which has been used for a long time and everywhere.
2. Double -circuit (two -pipe) – more effective during operation, with the possibility of regulating heat transfer.

Be aware that polypropylene should never be used on metal pipes when choosing a material for installation. The pipes used in a superior heating system are made of polypropylene.

Combining is not allowed in this area.

A single -circuit heating system

In a single-circuit system, the radiator and polypropylene pipes are connected successively.

This kind of device is straightforward schematically:

• A pipe coming from the boiler (feed) is connected to the upper entrance of the radiator.
• To the lower attach the discharge of the chilled coolant (return).

One pipe handles both the feed and return. This is a horizontal pipe that surrounds the system’s perimeter in a one-story building. This is a vertical pipe riser found in apartment buildings.

Installing a single-circuit system requires some subtlety because the bypass must be mounted here.

A bypass is a pipe (jumper) that is installed in between a check valve or feed valve. In order to automatically shut down one battery from the contour while maintaining a functional system, a bypass is required (for example, for repair).

Double -circuit system

Battery installations using a double-circuit system are done in parallel. The coolant enters through the withdrawal from the supply’s main pipe. The second (separate) pipe indicates that the return occurs in accordance with the same scheme. You can do without extra information in the form of bypas if each radiator has its own input. On the output, there is a shut-off crane (valve) that can overlap the feed in an emergency.

The double-circuit heating system is thought to be more contemporary and has a 10% increase in heat transfer efficiency.

You will need brackets or specialty hooks in order to fasten the battery to the wall. To support light radiators, two is sufficient. The need for one fastening for every three sections is used to determine how many brackets are needed for heavy batteries.

Keep in mind that radiators are always situated beneath windows. By doing this, the room doesn’t cool down and the warm air from the batteries is better circulated. After rising to the radiator from the windows, the cold air becomes heated and spreads throughout the space.

Polypropylene pipes properties

As you are aware, there are some operational limitations with polypropylene pipes. Under such a system, the working pressure shouldn’t be higher than 20–25 kgf/cm2 and the temperature shouldn’t be higher than +95 degrees. A 50-degree increase in temperature causes the polypropylene product to lengthen by 6.5 mm/1 m.P. Upon reaching the highest temperature of +95 degrees for this type of pipe, the pressure parameter becomes valuable and drops to 6-7 kgf/cm. The following conclusion would result from translating the provided digital indicators into the language of an ordinary layperson: only autonomous heating systems allow the connection of a radiator with a polypropylene pipe.

While the Central Control Service’s standard parameters (4 – 6 kgf/cm2, 50 – 95s) appear appropriate for this material, the actual situation is typically quite different. Generally, when central heating is in operation, one has to deal with conditions that are not met according to GOST and SNiPs. For instance, if the street temperature drops significantly, the elevator node may begin to function with a dried leak and no nozzles. Here, the coolant that powers the heating circuit comes straight from the main highway, where it can reach an operating temperature of +150 degrees.

Furthermore, internal pressure within a hydraulic unit can increase to a maximum of 25 to 30 kgf/cm2. This phenomenon is typically caused by the coolant being pumped into the system too quickly. Furthermore, polypropylene has a number of additional unique characteristics. Special compensators in the form of pipe bends are used because straight sections of heating are too long to be heated due to the excessively large extension indicator. By doing this, the likelihood of emergency consequences in deformations is greatly decreased.

It is also possible to prevent lengthening by using reinforced pipes, which have a lower temperature expansion coefficient:

• 3 mm/1 m.P./50s. In the case of use as a reinforcement of chopped fiberglass (fiber).
• 1.5 mm/1 m.P./50s. When polypropylene is reinforced with aluminum foil.

When using a fitting, the foil at the junction needs to be cleaned; otherwise, the pipe may grow out of it. This is flawed due to aluminum’s electrochemical corrosion while it’s in use.

In connecting aluminum radiators with polypropylene pipes for heating your home, you"re ensuring efficient heat distribution and durability. The combination offers a reliable solution for maintaining warmth in your living spaces while also being cost-effective. Polypropylene pipes are lightweight, flexible, and resistant to corrosion, making them ideal for installation in various layouts. Aluminum radiators are known for their excellent heat conductivity, ensuring quick and even distribution of warmth throughout the room. The connection between these two components is straightforward, usually achieved through compression fittings or push-fit connectors, eliminating the need for complex welding or soldering. By choosing this setup, you"re investing in a dependable heating system that promises comfort and energy efficiency for years to come.

What can be a strapping of polypropylene pipes

A home heating system’s binding can differ greatly. The problem lies in the fact that consumers constantly strive to use fewer consumables while still making every effort to install radiators in heated rooms.

It’s important to state up front that these are the ruins of the past. Polypropylene consumables are significantly less expensive and easier to install than pricey metal pipes. Thus, cutting the pipeline’s length is not worth it. Select the kind of strapping that will be most helpful in your situation. The following factors are the only ones that can affect the binding type selection:

• which heating circuit is used (one -pipe system or two -pipe);
• What type of connection of radiators have you chose (diagonal, lateral or lower).

Generally, you can use any kind of connection for your heating batteries when using a one-pipe or two-pipe heating scheme.

Note: Experts advise minimizing the amount of bends in the pipeline when it is laid. Hydrodynamic loads are still resisted by the flat line. There will be fewer areas in the pipeline where air can build up.

There are specific qualities for strapping polypropylene pipes in single- and double-circuit heating systems.

For a system with a single pipe:

• Typically, such a system uses a sequential connection of radiators;
• The bypass is always mounted in front of the battery, connecting the supplying pipe and return. With normal operation of the heating system, the bypass is not involved. When conducting preventive work or in the case of an emergency, the supply of water into the radiator ceases. The coolant unhindered circulates through the bypass.

Regarding a two-pipe setup:

• It is used, both parallel and consistent connection of batteries;
• Both radiator pipe are connected to different pipes. Upper to the supply pipe, the lower pipe is connected to the return. Typically, in two pipe systems, there is a parallel connection of radiators, so installing bypasses is not required.

There are two methods for strapping polypropylene pipes with radiator participation: soldering and using fittings. Plumbing keys and a soldering iron are used by Americans to install radiators and connect them.

Polypropylene pipes connected to aluminum radiators provide a contemporary way to have effective home heating systems. These materials’ compatibility offers longevity and flexibility, guaranteeing dependable performance over time.

The ability of polypropylene pipes to withstand rust and corrosion makes them an excellent choice for use with aluminum radiators. Polypropylene pipes last longer than metal pipes because they are resistant to deterioration from chemicals or moisture.

Furthermore, polypropylene pipes’ lightweight design makes installation easier, saves labor costs, and facilitates maneuvering in confined spaces. Because of this, they are the best option for both new construction and retrofit projects.

Furthermore, the effectiveness of polypropylene pipes is enhanced by the thermal characteristics of aluminum radiators. Because of aluminum’s superior heat conduction qualities, warmth is evenly distributed throughout the house, creating cozy living areas.

In summary, installing polypropylene pipes to connect aluminum radiators provides a dependable and affordable option for home insulation and heating. It is a favored option for contemporary heating systems due to its longevity, resistance to corrosion, and thermal efficiency, giving homeowners peace of mind and energy savings.
