Do -it -yourself polypropylene collector

Are you sick of paying a lot of money for heating and having cold rooms in the winter? Are you trying to find an economical and environmentally responsible way to heat and cool your house? You only need to look at the homemade polypropylene collector! With the help of this creative solution, you can heat your house effectively and economically by using solar energy.

In addition to their environmental impact, traditional heating systems can be costly to install and maintain. However, you can use renewable solar energy to heat your home without going over budget or negatively impacting the environment if you install a polypropylene collector. Furthermore, you will have complete control over the design and materials when you build it yourself, guaranteeing a customized solution that meets your needs.

So what is the operation of a polypropylene collector? While simple, it works well. It is basically composed of a number of heat-resistant and long-lasting polypropylene tubes. These tubes are grouped together in a panel and positioned so they can absorb sunlight in a key area, like your roof or a south-facing wall.

Heat is absorbed by the tubes when sunlight strikes them and is transferred to a fluid that is circulating inside. This liquid, which is usually a blend of water and antifreeze, transfers heat to a storage tank or straight to the heating system of your house, where it warms your interior. For do-it-yourselfers, this passive system is a great option because, once installed, it requires minimal maintenance.

Collector for heating: purpose, advantages and installation

The heating manifold serves as the central component of the radiation heating system, a cutting-edge and highly efficient solution available today. We will discuss the primary structural components of the heating collector, take into account the various comb types, and provide a number of pointers to make the installation process easier for you to do on your own.

Collector for a private home’s heating system.

Collector-ray heating system

The radiation type heating system’s collector.

It will be simpler to comprehend the fundamental advantages and functions of the heating collector if it is taken into account alongside the radiation scheme of the coolant wiring.

There are three primary varieties of pipe wiring, as you are aware.

1. One -pipe scheme. Here, radiators are turned on sequentially, that is, the coolant is supplied to the first device, then passes through the battery and enters the next, gradually passing the entire circuit and returning to the boiler. Obviously, after each radiator, the water cools down, and the heating of the batteries occurs unevenly;
2. Two -pipe scheme. This solution provides for the supply of water along one pipe, and the discharge is the second, that is, the circuit consists of two highways, between which radiators are parallel. This scheme allows you to warm the devices more evenly;
3. Radiation scheme. The coolant is supplied to the distribution unit (collector of the heating system), from where it enters each radiator through a separate pipe, and then returned back on the backbones, gathers a comb and enters the boiler. Thus, you can achieve the maximum uniform distribution of heat in the room.

Wiring schemes with one pipe and two pipes.

The wiring scheme for radiation.

Crucial! The radiation scheme has numerous contours, one for each battery, as you can see. Consequently, a circulation pump—which can supply the required pressure parameters and the coolant circulation speed—is needed for the system to function normally.

In addition to enabling you to modify the heat supply intensity to each battery, the radiation scheme enables you to heat each radiator as uniformly as possible.

Additionally, you can disable any device in this scheme without affecting how the system functions as a whole, and in multi-story buildings, you can turn off entire floors without affecting how coolant is supplied to the remaining parts of the structure.

Heating collectors, which are incorporated into the distribution node as the supply and reverse comb devices, are used to put these benefits into practice. The heating collector’s connection to flow meters, air and drain cranes, thermostatic heads, shut-off valves, and flow meters enables automatic temperature control for every heating device.

The supply can be changed thanks to the usage of consumer meters.

Crucial! This type of wiring is most frequently utilized in the construction of private homes’ and cottages’ heating systems, but it can also be utilized in apartments that have a central coolant supply. Keep in mind that it is best to install the pipes beneath the floor.

Radiation wiring also offers the benefit of allowing the pipeline to be hidden beneath baseboards or within the floor’s thickness. This characteristic frequently influences the wiring scheme selection.

For floor heating systems, the "warm floor" system invariably requires the use of a collector.

Not to be mentioned is a system known as a "warm floor." In order to warm it up, the contours in this area are laid out specifically in the floor screed rather than being connected to the radiators.

The cost of the materials and labor is the only real disadvantage of this approach.

Heating comb

Design

There are two crests on the heating manifold.

The comb is made of an inch or three-quarter pipe with threaded holes at each end. Connect the water supply or drainage mains at one end, and close the other end with a plug, air carrier, or crane to allow the coolant to be drained from the system.

In order to connect the "warm floor" or expand the heating system, you can gradually unscrew the plug or taps and add new links to the comb.

One can either drown out or add more links to the comb.

The pipe is additionally outfitted with aircraft to link heating pipes and nests to install regulatory reinforcement. Typically, the reverse part has thermal heads that measure the temperature of the reverse water and, if needed, open or close the flow meters, and the supplying part has consumable valves that control the supply.

Support structure for strapping combs.

Crucial! is feasible to create a binding circuit using straightforward tap adjustments; in this instance, manual control is used. Cranes are essential; without them, it would be impossible to repair or replace malfunctioning parts on the devices connected to the network.

Uncomplicated collector for distribution.

A comb may have a simpler structure when it comes to a simple binding by cranes because there is no need for a nest to install reinforcement. In the next section, we’ll talk about different types of structures.

Varieties

The materials, comb design, and complete set of heating collectors can vary.

Different distributor models can be identified based on the binding configuration, materials, manufacturers, and design. Depending on the devices’ intended use, there might also be variations.

Branded models with all the required reinforcement and devices are the most efficient and dependable.

These goods could consist of:

• Feeding and reverse crests. As a rule, made of high -quality brass or stainless steel;
• Circulation pump;
• Flow meters on the supply distributor;
• Thermostatic heads on the assembly node;
• Air valve or maevsky crane for air driving from the system;
• Crane for draining the coolant;
• Pressure gauge for pressure control;
• Brackets or other fasteners;
• Discharges for attaching wiring pipes.

The image displays a radiator heating collector with a brand.

Crucial! Branded models are gathered and staffed while considering every aspect of the apparatus and comb design. Generally speaking, such a system’s details are made for one another and function best in this mutual configuration.

Premium assemblies from top manufacturers can cost between twenty and thirty thousand rubles. If the price is too high for you, you can use less complicated and inexpensive gadgets.

Less expensive distributor.

An inch brass pipe with semi-inch terminations for wiring is a simpler type. The feeding section has only outputs, and there are nests for thermostat or consumerier installation on the reverse comb. It will be necessary for reinforcement to be chosen and installed independently.

This is by no means the simplest choice, though; Chinese goods are also available:

Cranes used for model casting.

Even less will be spent on a cast model with Chinese-made valves. Issues related to leaks and seal deterioration could exist near the valve unit. Because of the cast performance of products, replacing seals is frequently difficult or impossible.

Models of plastic distribution are also available. They are not as expensive and have decent quality, but their dependability is questionable. It is unnecessary to discuss durability at this time because time will tell as there are no trustworthy statistics or operational data yet.

Wiring for plastic collector heating.

Finally, tees can be inserted into an inch reinforced pipe to assemble a polypropylene distribution unit. This is the simplest and least expensive option, but its dependability tends to zero, so you could consider this to be a transient decision.

The least expensive and least trustworthy choice is a distributor of polypropylene.

Crucial! If you have a tight budget, it is best to cut back on interior decorations or finishes rather than saving money on heating because the finish will deteriorate first and the cost of a boiling water leak will be much higher.

Think about the installation process.

Installing the combs on the bracket is the first step in installing the heating collector. After that, the drain valve and air vent are installed after the plugs are unscrewed.

After that, the nest caps are taken off, the flow meters for the feed are mounted, and thermal controllers are placed on the return. The pump is installed if it isn’t there at first.

Typically, the pump is set to reverse highway.

The bracket is then fastened to the wall or the camshaft after that. When a component is assembled and tested, it can be used to connect components of a digital signage system or a telephonic system. The major pipes are connected at the end, and a specialized pump crimps the system.

The mixing node is used to lower the water’s temperature on the heated floor.

Crucial! This is a draft instruction that may change based on the hardware being used and the setup of the system.

The property’s most advanced water heating system is collector heating. Its implementation makes use of a variety of distributor models, the most successful of which are thought to be proprietary European products with full configuration. This topic will become clearer to you after watching the video.

How to make a distribution collector for heating a house with your own hands

The efficiency of the home’s sophisticated heat engineering complex, the heating system, depends on installation regulations being followed. Experts advise installing a distribution collector if it has multiple circuits so that you can regulate the heating of each circuit independently.

What is it needed for?

There is a rule that must be followed when installing water systems: the feed pipe’s diameter cannot be greater than the combined diameter of all layers. This rule applies to heating equipment and reads as follows: two contours with ½ inch pipe diameter are permitted in the system if the boiler’s output fitting has a diameter of one inch. Such a system will function well for a small house heated solely by radiators.

Warm floors are actually one of the more prominent heating features in a private home or cottage. heating the garage, utility rooms, and multiple floors. If they are linked by a layering system, there won’t be enough pressure in each circuit to heat the radiators efficiently, which will result in an uncomfortable home temperature.

As a result, collectors operate branched heating systems; this method enables you to independently modify each circuit and establish the ideal temperature in every room. Thus, you need a temperature of about plus 23–25º for the nursery and enough plus 10-15ºΡ for the garage. Furthermore, warm floors shouldn’t get hotter than 35 to 37 degrees because that will make them uncomfortable to walk on and may cause the flooring to warp. This issue can be resolved with the aid of a collector and locking temperature.

In this video, a collector system is used to heat a home.

Heating system collector groups are offered in their completed state, albeit with varying configurations and discharge counts. Selecting the appropriate collector assembly and installing it yourself or with the help of experts is an option.

Nonetheless, the majority of industrial models are general-purpose and may not always meet the requirements of a particular home. If they are modified or refined, the expenses can go up dramatically. Therefore, considering the characteristics of a particular heating system, it is generally easier to collect it from separate blocks with your hands.

Collector group for the heating system assembly

The figure depicts the layout of the universal collector group. It is made up of two blocks with the appropriate amount of coolant installed for both direct and reverse currents. Flow meters are mounted on the supply (direct) manifold, and thermal drives are positioned on the opposite side to control the temperature of the reverse water in each circuit. They will assist you in determining the necessary coolant flow speed, which will control the heating radiators’ temperature.

Air valves, a circulation pump, and a pressure gauge are all installed on the collector distribution node. With the help of brackets, the supply and reverse collectors are integrated into a single block that is fastened to the wall or cabinet. Such a block costs between 15,000 and 20,000 rubles. Furthermore, it will be obviously inappropriate to install it if only a portion of the bounces are involved.

The video demonstrates how to install the completed block.

Grebanka – collector knot

Thermal drives and flow meters are the most costly components of the collector distribution unit. You can purchase a collector node, or "comb," and install the required control devices manually only where they are required to avoid paying too much for extra elements.

Brass tubes measuring ¾ or 1 inch in diameter are used for the rowing, and there are a specific number of sets with ½ inch heating pipe diameter. The bracket serves as another link between them. The reverse manifold layouts come with plugs that let you install thermal drives on all or just some of the contours.

Certain models have the ability to manually adjust the supply with the assistance of cranes. These combs feature a cast housing and a threaded fitting or nut on the ends, making it easy to quickly assemble a collector from the necessary number of layers.

You can make a collector entirely by hand or collect from individual elements to save a collector for heating systems.

Do it yourself

It is possible to make the heating system’s distribution collector independently out of metal or polypropylene. Functionality is unaffected by material selection, so go with what will be easiest for you to mount yourself.

A metal-welding inverter, specialized equipment for welding polypropylene pipes, and the necessary labor are required for the installation of a polypropylene collector unit.

Calculation and distribution of contours

Before starting work, it is necessary to determine the required number of heating contours and perform the drawing of their connection. It is advisable to highlight individual contours to the following heating devices:
• warm water floors in each individual room;
• heating of rooms, the temperature of which differs from the rest in a larger or smaller direction;
• heating each individual floor and wing of the house.

The collector’s geometric measurements should guarantee that the locking and adjusting mechanisms of each layer are easy to access and lightweight. It is recommended to leave an average of 10-15 cm between layers and 20-30 cm between the supply and reverse manifold.

The pipes used to connect heating radiators typically have a ½-inch diameter, while the collector measures 1-1½ inches. This ensures that the pipes match the boiler nozzle diameter. The supply and reverse pipe connections for gas and electric boilers may be made upper and lower; only lateral connections for solid fuels are permitted.

Polypropylene knot

It is constructed using fittings and leftover polypropylene pipe scraps. Welding pipes requires a specialized tool. A polypropylene pipe measuring Ø32 mm and tees measuring 32/32/16 mm are utilized for the feed and reverse manifold, and they are joined by a polypropylene welding apparatus. Before using pipe scraps, the mode is chosen.

The drain valve is connected to the installed tee 32/32/32 mm at one end, while the air valve is installed at the other. At the opposite end of the collector is an introductory valve, to which the boiler’s supplier or reverse pipe is connected.

Court valves are linked to the supply collector’s 16 mm settings and the flow meters on the other end. Using brackets, the acquired nodes are fastened to the wall.

Brass fittings knot

In a similar vein, a collector can be put together using pre-made brass fittings like valves and tees. They are gathered using a liquid fixer or linen dad in accordance with a prearranged plan. Such a collector has the benefits of being inexpensive and small in size. in contrast to the group of completed collectors. However, careful attention to detail and precision are needed during assembly to prevent leaks during operation.

With a profile pipe with your own hands

Welding is the most challenging design element in the distribution collector. constructed from pipe with a square and round cross section. These collectors have a hydraulic shotgun-stream distributor and are used to heat large objects with multiple contours.

Use a round section with the calculated diameter and a profile pipe measuring 80 by 80 or 100 by 100 mm when manufacturing the collector. The technology and detailed instructions needed to manufacture a collector are provided below.

• It is necessary to prepare a sketch of the future heating system. To do this, you need to determine all the connected contours and diameters of the pipes, as well as the equipment additionally connected to them – flow meters, manometers, circulation pumps.
• On the sheet of millimeters or leaf into the cage on the scale, perform a drawing of the collector node, withstanding the distance necessary for the convenience of installing the distance. Between the pipes, it is recommended to make 10-20 cm distance, between collector units-20-30 cm. In the drawing, you need to indicate not only the distances, but also the diameters of the pipes.
• Decide on the installation site of a collector group and auxiliary equipment: an expansion tank, a pump, a boiler security group, boiler. Check the overall dimensions and make sure that the collector group is installed without interference with other equipment.

• Profile pipe is marked in accordance with the scheme.

• The gas cutting openings are made by the gas cutter.

• They welcome nozzles to them – small segments of a round diameter pipe with pre -chopped thread. First grabbed with point welding, and then boiled along the contour and carefully protect the seams.

• Fasteners are welded to the resulting block.

• The resulting collector group is cleaned from scale, pollution, rust, after which it is primed and covered with heat -resistant paint for metal. For the convenience of maintenance, the supply and reverse contours are best painted in different colors, traditionally – red and blue.

The video demonstrates how a camshaft is made from a profile pipe.

It is advised to install hydraulic arrows in complex systems with many contours serving different purposes. These arrows will distribute and align the coolant’s straight and reverse flows to a safe pressure and temperature.

Video: hydraulic arrow: its function and working principle.

Solar collector – the possibility of saving

Multiple coolant heating sources can be connected to the heating circuit. Solid fuel boilers frequently operate in tandem with electric ones. This enables you to maintain the heating system’s operating mode during the night or for a few days when the hosts are away.

However, this regime is not economical because electricity is one of the priciest resources. By installing a solar manifold, you can use modern advancements to harness solar energy to heat the coolant.

Installing a solar collector allows for year-round use, even in overcast weather. It works best on sunny days, reaching temperatures of between 70 and 90 degrees, depending on the boiler’s shape.

DIY solar collector

The solar manifold is an extremely easy-to-assemble device that can be made by hand. Although a homemade solar water heater may not be as efficient as an industrial model, considering their cost—between ten and one hundred fifty thousand rubles—a solar manifold you make yourself will quickly pay for itself.

To manufacture it, you will need:

• A coil of a metal tube, usually copper, can be taken suitable from the old refrigerator;
• scraping a copper pipe with a 16 mm thread on one side;
• plugs and valves;
• pipes for connecting to a collector node;
• a boiler tank with a volume of 50 to 80 liters;
• wooden strips for the manufacture of the frame;
• a sheet of polystyrene foam 30-40 mm thick;
• glass, you can take the window;
• Aluminum thick foil.

After the coil is freed from the freon residue, it is cleaned with a stream of running water. They construct a frame the size of a slightly larger coil out of a wooden rail or bar. To remove the snake tubes, holes are drilled in the lower portion of the frame.

A leaf of polystyrene foam is screwed to the reverse side, which will serve as the collector’s bottom. Excellent thermal insulation properties of this material will aid in lowering heat loss.

The foil is positioned from the interior, fully overlapping the frame’s wall and bottom. Stapler is used to secure foil to brackets. Insert a coil so that its ends spread out into the opening in the frame.

The solar manifold is secured to stacks or rails by a glass cover on top. The coil’s ends have pipes fastened to them so they can be connected to the heating collector unit. Flexible eyeliner or adapters can be used for this.

The collector is positioned on the roof’s southern slope. Pipes are introduced into a storage tank that has an air valve, and then they go to the heating camshaft.

How-to video: building a solar heater at home

The best method for connecting different heaters to one or more heating sources is the collector heating system. With it, you can maintain a constant and well-coordinated operation of all system components, as well as a comfortable and consistent temperature throughout the house.

Collectors for heating – installation, calculation and installation with your own hands

The installation of a heat supply system is a necessary expense during building construction. Because of this, you should carefully consider how to make a heating collector with your hands when designing your own house or production building. There is no way to prevent issues when operating and maintaining heating equipment in the future if there are computation errors in the plan.

In order to achieve a heating system that differs in high performance, it is also necessary to select the appropriate wiring method for the pipelines. This will affect both the heating system’s collector’s ability to function effectively and without resistance. The installation of pipes from the thermal energy source to heat radiators is the most popular radiation-based or combined radiation solution.

Features of the radial scheme of collectors for heating

When a house has multiple floors or a building with a large number of rooms and utility rooms, the polypropylene heating collector scheme depicted in the photo can be deemed optimal.

You can greatly improve the structure’s performance if you install the heating collector in this case. As a result, it will be feasible to guarantee optimal heat transfer and greatly minimize heat loss. The collector is used to operate the heating option’s equipment, which is characterized by its simplicity and the existence of specific features. See also: "A collector using your own hands for a warm floor."

Therefore, based on the connection scheme, the heating collector will be installed on each floor (there may be more than one floor occasionally), and pipes will already be made from it. The installation of the heating system’s components is typically done in the walls or cement screed, according to the instruction.

To avoid ruining the foundation for laying the flooring, the heating structure project and its branching should be completed before repair work is started.

Elements of the heating circuit

Contemporary heating, which uses collectors to provide heat, necessitates building a sizable structure with the following primary components:

1. The source of thermal energy. It is the first starting point from which the heated coolant is sent to pipelines and heating radiators. The power of heat units must be accurately calculated so that the equipment functions in accordance with its purpose.

When building a heating structure, selecting a boiler and figuring out its specifications is a crucial step. The rooms won’t be warm enough because the low power indicator prevents the circuit from operating at maximum capacity. The fuel will be overspent due to the overestimated necessity of heat transfer, which will necessitate the installation of regulatory components and consequently additional costs;

• Circulation pump. Closed heating circuit with a comb requires forced circulation of the coolant. To do this, install circulation pumps in the heating system. thanks to which the necessary pressure is created to move the heated fluid, the optimum temperature guarantees high -quality operation is provided.When choosing a circulation pump, according to the instructions, take into account a number of parameters. The power of the engine of the circulation device does not apply to the main indicators, it only determines the amount of energy consumed by the engine. Attention should be paid to the speed and volume of the pumped liquid per unit of time. You need to choose the pumps very carefully. The fact is that in order to ensure high -quality heating, it is necessary to select it with a margin by power, exceeding the calculated parameters by about 10 percent, since often real estate owners add the heating area without replacing the circulation device.
• Collector for radiator heating. It is an important element of the heat supply system by analogy with the boiler or pump. It is the collector for radiator heating that gives the “radiation” scheme, since it performs the distribution function and ensures the supply of liquid coolant to all heating batteries.For such systems, various shut-off or thermoregulating elements are additionally used. Thanks to the collector, in each branch of the heating structure it is possible to ensure the necessary flow rate of the coolant. Installation of thermometers and automatic air accessors additionally guarantees high -quality operation of the heating network without costs (read also: “Installation of the heating systems of the house according to the rules“). Selection of the type of comb, and their choice in the domestic market is huge, are carried out in accordance with the planned number of heating contours and heating radiators. In addition, distribution collectors for heating are distinguished in accordance with the material of manufacture, they are made of steel, brass or polymeric materials.
• Cabinets. This type of heating structure needs to hide its components, such as a collector for heating with your own hands, pipelines, ball valves in boxes or cabinets specially equipped for this. They are either fixed on the outside or built into the walls.

Choosing pipes

The primary pipeline parameters must be coordinated before any work directly related to the construction of the heat supply system can begin. The pipeline, the collector’s entrances and exits, and the thermal energy source should all have the same diameter. Otherwise, adapters are used when using pipes with varying diameters. The installation of these demands more time and money for materials.

Although there are various materials for the supply and return pipes used to transport liquid coolant, experts advise utilizing polypropylene pipes (see "Installation of the heating system from polypropylene pipes with their own hands" for more information).

Their accessibility, usefulness, and simplicity of use during installation are their advantages. Hydraulic calculations should be used as a basis for choosing polypropylene pipe.

When pipes are not cut to the specified diameter, the following bad things happen:

• violation of the circulation of the coolant;
• Publishing the heating circuit;
• Uneven heating.

Radiation scheme and warm floor

The "warm floor" system and a homemade collector for heating can be combined using the radiation scheme. However, there are several features in this design.

Prior to beginning the process of creating it, you must familiarize yourself with them:

• The installation of the heating collector should be carried out provided that it will be equipped with adjusting valves and thermostatic valves on absolutely all contours;
• When wiring pipes for the heat supply system, the “warm floor” will certainly use electric -the -floor drives and thermostatic heads. Thanks to these devices, “warm floors” will be able to quickly respond to a change in the temperature regime and maintain the necessary microclimate in each of the premises;
• The option for arranging the distribution system can be different – typical (executed according to the standard scheme) and individual. The last way deserves special attention. In this case, the boiler works in normal mode without significant temperature jumps, and fuel is consumed economically.
