Strapping a solid fuel boiler with polypropylene

Having an effective heating system is essential for keeping your house warm and comfortable during the winter. Solid fuel boilers are a dependable and economical option for home heating, and they have been for a long time. To maximize your boiler’s performance and energy efficiency, however, you must make sure it is installed and insulated correctly.

In the field of installing solid fuel boilers, strapping with polypropylene is one technique that is gaining popularity. This creative solution offers many benefits over conventional techniques by using polypropylene straps to hold the boiler in place. Installing solid fuel boilers is being revolutionized by strapping made of polypropylene, which offers improved insulation and increased durability.

For strapping applications, polypropylene is a thermoplastic polymer that is both lightweight and sturdy. Its high tensile strength ensures a secure hold once in place, and its flexibility makes it easy to maneuver during installation. Furthermore, polypropylene has outstanding resistance to chemicals, moisture, and temperature changes, which makes it perfect for use in heating systems.

Improved insulation is one of the main advantages of using polypropylene strapping on a solid fuel boiler. Heat loss is reduced when the boiler is firmly secured in place with polypropylene straps, which enhances energy efficiency and lowers heating expenses. In addition to keeping heat from escaping into empty spaces, this additional insulation helps keep your home comfortable and warm throughout.

What it is?

Put simply, this is a series of steps that involve connecting and calculating different parts. This is required in order for the boiler to operate as efficiently as possible and for the entire system to operate in harmony. High efficiency and economical energy use will result from this.

The components of the strapping

The selection of a system type will determine the set of components:

  • natural or gravitational circulation;
  • forced circulation;
  • mixed.

For the first choice, it will look like this:

  • Boiler. This is the heart of the whole mechanism. It is he who, heating the liquid, makes her act in accordance with the laws of physics – to rise up and go through the contour. Then, cooling, she returns to the original point. For the option of natural circulation, floor heating devices are used.
  • Pipes. For such a solution, large -diameter metal pipes will be relevant (in some cases, the supply pipe can be 2 ″). This is important so that there is no resistance from the highway for free water circulation.
  • Expansion tank. It can be either open – to contact with the environment – and a closed type – not to have contact with air. Additional membranes are not used here, t.To. there is no need to maintain a given pressure. It is mounted at the highest point of the entire system.
  • Batteries. Both cast iron and steel radiators can be used.
  • Maevsky crane. It is desirable that it be installed on all batteries where this is necessary. In this case, at any time, it will be possible to lower air from the battery .
  • Fitting. Most often used metal threaded or welded corners, tees, bounces and other connectors.

The simplicity of installation, accessibility of all parts, and potential for independent installation are the benefits of this kind of system. Among the drawbacks are the substantial component dimensions, which are greatly influenced by appearance. Inertia, or the gradual heating of the entire wiring, is the other side of the coin.

Strapping components for mandatory circulation systems

The parts of forced circulation systems will look like this:

  • Boiler. In this case, you can use any option. The strapping of a wall device is fundamentally similar, but includes additional elements. Also, this type of heaters is equipped with additional protective systems.
  • Pipes. With this implementation, both metal and all types of suitable plastic products can be used.
  • Expansion tank. Here he is a membrane type. “Pear” is located inside it, it allows you to maintain pressure inside all contours at the same level. Usually installed near the equipment.
  • Radiators. The same options can be used as in the previous scheme. Steel will be more economical. They contain a smaller volume of water, so its heating is carried out faster and less fuel goes to this.
  • Cranes of Maevsky. Installation is the same as in the previous version. In addition, the discharge valve for air can be mounted, which automatically removes it from the contours.
  • Fitings are selected depending on which pipe is used in installation.
  • Circulation pump. Usually it is already installed in the heating device. In the presence of several circuits using the collector, additional units are mounted.
  • Hydraulic arrow. This is a very important element that makes it possible to create a balance between different contours in the radial location scheme. It is designed to level pressure and guarantee timely supply of hot media to each point.
  • Manometer. Usually present in all modern equipment. If it is not, then it is installed next to the heating device. It is necessary in order to control the constancy of pressure within the entire system.
  • Collector. To the element from which the wiring of various contours is carried out, the coolant is supplied.

Heat-producing collector

Advantages of this type of wiring include a high coolant heating rate throughout, more economical gas flow, or electricity. Using this option, the contours’ length can be increased to enable the installation of a water-warm floor. The high cost of labor, some maintenance challenges, and the inability to operate in the absence of electrical energy are typically the drawbacks.

Bypass installation in the heating system

There are two ways to conduct circulation in a mixed system. Without distorting it, the pump is sliced parallel to the primary contour. The device has a shut-off mechanism on the main pipe underneath it and two taps installed on the carts to allow for constant shut-off. If the pump is operating, this valve will be overlapped. Installing a check valve in place of a tap is necessary if you want the system to run in automatic mode. Typically, metal pipes make up the entirety of the system.

Recommendations for strapping polypropylene

Heating is done using polypropylene.

Plastic pipes are widely used. This is due to the affordable price, as well as universality. Thanks to this solution, you can pass any obstacles and make a contour of any complexity. Pipe joints are carried out using fittings and soldering iron. If possible, it is better to try to do as few compounds as possible. This is due to the fact that in the rations of the soldering the inner diameter is often made, and this creates unnecessary hydrostatic voltage and lowers the efficiency. If the design allows, then it is better to use the dampings with a smooth transition, this will exclude sharp changes. Modern polypropylene can withstand the temperature of the media up to 95º, the service life is up to 50 years without the need for serious maintenance.

Choosing a place

Selecting an area for a boiler

Floor boilers are typically chosen for systems with natural circulation. He must meet one crucial requirement in order to be defeated: it must be at the lowest point on every circuit. The fact that air bubbles shouldn’t build up in it explains this. The heat exchanger will burn more quickly if not. In order for the air to rise and then be removed through an open expansion tank or a special reset valve, there should also be a pipe at the output that is positioned vertically after the transition.

This condition might not be met if a forced system is installed. When installing wall samples for a basement heater, it is possible to place them at the lowest point as well as the highest point in certain situations.

In addition, it’s important to make sure the double-circuit boiler is connected to the water system before binding it. It is essential, t.To. In addition to heating the coolant in the heating system, it also heats the water that runs for domestic purposes. A similar scheme can also be applied for a single circuit. However, installing a secondary heat exchanger is the only way to make this happen. Its function could be that of a metal cylinder that the system’s supply pipe is embedded through.

Solid fuel boiler nuances

Location selection for a solid fuel boiler

Such equipment cannot be simply switched from electric to gas or vice versa. Nothing will change if loading was done up until the fuel runs out entirely. Protection systems must therefore be provided with such strapping. They come in a variety of forms:

  • Using tap liquid. To implement this option, a special device is purchased. In appearance, he resembles a heating element. It is built into the heat exchanger, some manufacturers specifically provide an additional input for such solutions. After that, running water is supplied, and the outlet pipe is lowered into the sewer. The essence of the method is that when the circulation pump is stopped due to the lack of electrical energy or breakdown, the valve opens, which starts cold water, it, passing along the coil, picks up part of the temperature, after which it is dumped into the sewer. The process continues until the fuel is completely burned out. In some situations, this method will be ineffective, t. To. When the light is turned off, the pressure in the water supply also disappears.
  • Uninterruptable power source. Various options are available today. Most of them support the connection of external batteries. The duration of functioning will depend on the selected battery capacity. The pump to the network in this case is connected through the UPS. As soon as electric energy disappears, the device comes into business, which maintains the performance of the pump until the moment when the power supply to the house is restored or the batteries are not discharged until the batteries are discharged.
  • Small gravitational circuit. Implies the circulation of the carrier in a small circle that does not need the use of the pump. It is made in compliance with all slopes and pipe diameter.
  • Additional gravitational circuit. This option implies the presence of two full circuits. Moreover, when an emergency dangerous situation and forced circulation disappears, hot water under the influence of physical laws continues to flow into the second circle, giving the temperature to heating devices.

Safety elements

These are extra parts that are, for the most part, already present in contemporary boilers.

  • Automatic reset valve. In appearance, it can resemble a structure similar to a valve or a small barrel with a nipple in the upper part. In order to find out if it is in the design of the device, you need to look at the design features of the pipes for connecting, it usually is located there.
  • Gryazaulter. A special flask that allows you to remove unnecessary elements from the contours of heating that got there when filling the system. It is installed before entering the boiler. Periodically it is necessary to clean it.
  • Carrying filter. An ordinary tap is used. It is usually mounted at the entrance of the main highway to the equipment.

The sequence of installation works

Setting up a boiler for heating

  • Installation. If a solid fuel version of the boiler is used, it is necessary to make sure that there is a strong base under it, which will be resistant to high temperatures. For a gas floor and wall turbocharged version, a hole is made in the wall, through which a pipe is displayed for dumping the exhaust gases and the receipt of fresh air. For a chimney option and hard -fuel equipment, an additional pipe is required to the required height to create traction.
  • Connection with the chimney. For modern samples, a special pipe with two sleeves is provided, one goes inside the other. One is concluded by one, according to the other -. In other versions, a clay solution is used to seal the seam. It is undesirable to use cement, t. To. It cracks quickly.
  • Ensuring good air supply. For solid fuel, you can additionally put the supply valve, with which it will be possible to adjust the incoming air and the burning force.
  • Installation of pipes wiring. When the device is installed, it is easier to navigate how best to lay the highway.
  • In parallel, the systems are connected that will ensure security, as well as expansion tanks.
  • Installation of a circulation pump, if necessary.
  • Installation of additional temperature sensors.
  • Connection to a gas pipeline. It must be remembered that such a connection should be hard without using flexible hoses.

You cannot cut costs on parts while ignoring security measures. Numerous factors, chief among them the device itself, will determine precisely what wiring method applies to your situation.

Polypropylene heating boiler strain diagrams

These days, a lot of people are interested in topics like using polypropylene to strap heating boilers. Plans and picture examples will undoubtedly be helpful in completing this task. But are these financial outlays and laborious efforts worth it? Actually, you’ll need to start from the very beginning to provide an objective response to this question, explaining what a binding is, why it’s necessary, and what kind of material polypropylene is. You’ll be able to determine for yourself whether to accept such a job or, better yet, go for something else by providing answers to all of these questions.

The purpose of the strapping

A tie is referred to as a complex of heating components that directly maintain the heater’s continuous operation by supplying the batteries with heated coolant. It also increases the overall system’s reliability and ensures that heat is distributed evenly throughout the house.

In actuality, the boiler’s strapping is the result of precisely calculating each system element’s parameter while accounting for the precise location of each component. Not only should heating produce heat, but it should also work dependably. Therefore, this issue needs to be given special consideration if a large number of additional elements are planned.

It is important to note that strapping is not universal. The particulars of the heater and the components that will be a part of the system must be considered in each situation. However, there are several guidelines and tools that are constant. Regardless of the fuel type and the boiler itself, the system for strapping polypropylene should be:

  • a boiler of a single -circuit or double -circuit type;
  • Expansion tank – an ordinary container (for a natural system) or hydraulic with a membrane (for a forced system);
  • Polypropylene pipes and fittings to them;
  • radiators – can be made of steel, cast iron, aluminum or bimetall;
  • Bypasses – are used in more complex strapping systems, as they allow you to disconnect certain sections of the water supply from the contour.

There are two types of heating systems: forced and natural. In the first scenario, the coolant flows through the pipes in accordance with physical principles, and in the second, the strapping incorporates a circulation pump. As a result, installing the Maevsky crane and the pump will be required for a forced type in addition to all of the previously mentioned components.

This is required for the collector if the circuit indicates that coolant is supplied to each device for each highway. Water is supplied and returned via pipes using this kind of device. The system also integrates the control devices, such as the pressure gauge, thermostat, and hydraulic arrow, when it becomes necessary to regulate the qualitative and quantitative characteristics.

There are subtleties to the strapping that you should become acquainted with. If not, there is no assurance that the heating system will function as intended. Depending on the kind of boiler, one can either hire experts or complete the work on their own. In the event that one lacks self-assurance, it is advisable to promptly seek guidance from the experts.

Ways to strapping boilers

Both natural and required circulation have already been discussed above. It’s time to learn more about this topic in depth:

  1. Natural circulation. This is the simplest and most affordable heating system, which can be able to cope with it with your own hands. This type is also called gravitational, since here the water acts under the force of gravity, so there is no need to mount the pump. Such a strapping is suitable for 1-2 storey private houses. The strengths of the installation include the strengths of the installation, there is no dependence on electricity, the cheapness of the installation, it is always possible to eliminate problems with your own hands. But without minuses it was not done here. Firstly, it is necessary to accurately calculate the diameter of the pipes, otherwise the full heating cannot be achieved. Secondly, such a system is difficult to hide in the interior.
  2. Forced circulation. The main difference between such a binding is the presence of a pump. This allows you to significantly expand the functionality, and in addition, the owner has the ability to adjust the coolant. If desired, a separate temperature is set for each room. This strapping scheme is suitable for both floor and wall boilers. True, it costs quite expensive. It is worth knowing that the pump is working from electricity. That is, if light is lost in the house, then the heating will decrease. Although this issue can be resolved by installing an uninterrupted power source. But, again, these are additional investments.

The more sophisticated the home’s heating system (warm water floors, for instance), the more modern strapping you’ll need. Thus, these kinds of issues need to be considered right from the start.

Polypropylene strapping schemes

Nowadays, polypropylene is frequently utilized in heating systems because it is readily available and simple to install. This kind of material interacts well with all kinds of coolant because it is not afraid of corrosion. Such pipes have an extended internal purity, meaning they will last for more than a dozen years, which is also facilitated by the smoothness of the internal walls. Polypropylene works well in both closed and open systems.

Unfortunately, this material has a high coefficient of thermal expansion, so when installing these pipes, that needs to be considered. Experts advise just purchasing multilayer reinforced pipes, the structure of which is designed to handle this kind of issue, as a solution to this problem. The polypropylene pipe with the PN25 marking is the best choice. Regarding the binding itself, this could be the case based on the current boiler.

  1. A gas boiler. In this case, the strapping must be performed with a hydraulic shotgun and collector. Most modern devices already have a built -in pump, so it is rational to use them in forced systems. Here, a polypropylene strainer is performed according to the scheme where circulation equipment will be located for each circuit behind the collector. This approach ensures high safety of operation, since the built -in pump will pump pressure only on a small segment of the pipeline – from the water heater to the distributor. But then pumps are already entered into the work, which are designed for the main load. A gas boiler with polypropylene pipes can do without long metal pipes, but only if the coolant has a temperature not higher than 75-80 degrees. With a cast -iron heat exchanger, an additional heat accumulator is an obligatory element in the circuit. It allows you to smooth out the temperature differences of water that are harmful to cast iron. If the boiler is double -circuit, then another filters of thin and deep cleaning are necessarily installed. The place of their installation is at the entrance to the water heater, where cold water gets.

  1. Solid fuel boiler. This device is characterized by inertia when the fuel is stopped. That is, while there is at least some fuel in the furnace and it burns, the coolant will continue to heat up. And here there is a snag – this process negatively affects polypropylene. Therefore, when strapping such a boiler, it is necessary to immediately mount the pipes from metal to the device, and after 1-1.5 meters to switch to polypropylene pipes. Experts also note that a prerequisite here is a backup supply of cold water. It will serve as emergency cooling for the heat exchanger, but it is also taken to the sewer. In the case of forced circulation, a source of uninterrupted nutrition is built into the system. Although this is not a compulsory rule, the fact is that the pump cannot work without electricity, which means that if the light suddenly turns off, then there will be no heat in the house. It is also recommended to create a small gravitational contour or equip the batteries with bypasses. This will allow, if necessary, to disconnect the areas from the overall system. This approach provides convenient repairs. A prerequisite for a solid -fuel boiler is a casing with which it is covered. It provides heat preservation so that it does not go away from the walls over the entire firebox. But at the same time, the collector and polypropylene pipes should be far from the boiler itself.

  1. Liquid -fuel and electric boilers. Here the strapping scheme is similar to the previous option. Pipes should be located as far from the boiler. By the way, polypropylene is perfectly “triggered” with electric devices, as they have automation, namely, it does not allow water to warm up to critical temperatures. Here, too, a hydraulic accumulator is installed and excessive pressure reset valves, as they will provide protection against hydraulic strokes.

Fitings and pipe from polypropylene are connected by a threaded method. But hot or cold welding is also allowed. Despite the fact that it is much more convenient to screw up, such a connection will cost many times more than welding, since here for each connection you will need a separate element. BUT! If the work is carried out at the connection of polypropylene with metal pipes, then you can not do without threaded fittings. Hot welding is carried out with a soldering iron or "iron". At the same time, polypropylene itself needs to be heated to 260 degrees, and only after that the softened parts are connected together. When working with reinforced pipes, do not forget about the cleaning of the foil, otherwise the joint will turn out not reliable. And in other cases, such a procedure is not required. For cold welding, a special glue is used, which is easy enough to buy in a specialized store.

It is imperative that sealing be considered when connecting the system. It is advised to use panit or high-temperature sealant for these uses. Every joint undergoes a strapping process.

Additionally, it’s important to know that if you intend to use antifreeze in your polypropylene pipe heating system, you must refuse this type of material. Water is the best choice in this case because antifreeze contains a significant number of chemical compounds that are harmful to plastic.

It’s not that hard to make a boiler with a cauldron by hand. The primary factor will be the type of boiler equipment and the cost of all required components.

34-year-old Konstantin Evdokimenko, g. Krasnoyarsk

When we made heating at home, my neighbor helped me, since he is engaged in the strapping of heating systems. We installed a natural circulation scheme, due to which we managed to save on the acquisition of a circulating pump. My comrade explained that polypropylene pipes are perfectly coping with the heating load, and I would say that they are quite acceptable. But what I want to say. It turns out that the expansion tank in such a scheme constantly contacts the environment, which is why it is saturated with oxygen. But it turns out that this negatively affects heating. Therefore, the neighbor created me an air circuit where all the air gathered and divert. I also want to say that in the future the natural system can be converted into forced, by inserting the circulating pump. But for this issue I will already turn to professionals.

G. Tomsk; Alexander Sanuzev, age 26

I work in a company for installing boiler equipment and installation of heating systems – my job. Today forced circulation is becoming very popular. Of course, it is expensive. But, we always offer our customers to reduce it, due to polypropylene pipes and the principle of primary and secondary rings. As for the pipes, such material is reliable, which means that after 5-10 years, when you have to change the boiler, the system can be left not touched. And this will save money. Well, about the rings, I want to say the following – this approach helps to reduce the number of devices on the network. For example, several rings with a boiler of 50 kW are complemented. This allows you to evenly distribute the coolant into radiators.

42-year-old Nikolai Kopanev, g. Gdov

After reading the article, I want to leave my opinion. The fact is that I sell, just polypropylene pipes and would like to say a few words about them. Such pipes have their own variety, and each type copes with heating and even in systems similar to such purpose. There are three main markings – PN 10, PN 20 and PN25. The first species is thin -walled products, so they are good only in a single -circuit scheme. In this case, the pressure should not exceed 1 MPa, and the temperature of the coolant should not be higher than 45 degrees. The second type is reinforced, so they are used in DHW branches, where there is a double -circuit boiler. The permissible nominal pressure in the system up to 2 MPa with a temperature of not higher than 80 degrees. And the last type reinforced, made using aluminum foil. Designed for systems with a pressure indicator up to 2.5 MPa, are able to withstand the temperature up to +95 degrees. Therefore, depending on what heating is planned in the house and you need to select a specific type of pipes. At the same time, I would not recommend saving, as there is always a risk of breaking through.

How is a strapping of a solid fuel boiler done

The quality of a solid fuel boiler’s strapping determines how well it will function going forward and how long it will last. Wood and coal heat generators are different from all others in this regard, so handling the problem differently is necessary.

Thus, when installing a heating system, it is important to think about how to connect a solid fuel boiler, even if you have to do it by hand. This material contains the answer to this query as well as a list of all possible ways to connect the unit to other heat-sized equipment.

The use of polypropylene strapping for solid fuel boilers offers a viable option for those looking to create a warm and energy-efficient home. Choosing polypropylene piping will help homeowners prolong the life and efficiency of their heating systems. Polypropylene is resistant to corrosion and scale buildup, making it a more dependable and low-maintenance alternative to conventional metal pipes. Its thermal qualities help to increase energy efficiency, and its flexibility makes installation simpler and more affordable. Homeowners can achieve effective heat distribution throughout their properties with polypropylene piping, which will result in reduced energy costs and increased comfort.

What is the difference between solid fuel boilers

Apart from generating thermal energy through the combustion of diverse solid fuels, these heat sources differ from other heat generators in several other ways. Since these variations are directly caused by burning wood, they should be accepted as inevitable and taken into consideration whenever the boiler is connected to the water heating system. These characteristics are:

  1. High inertia. At the moment, there are no ways to sharply extinguish the flared solid fuel in the burning chamber.
  2. Condensate formation in the fuel. The peculiarity is manifested during the flow of a coolant with a low temperature (below 50 ° C).

Note: Only one kind of solid fuel unit—pellet boilers—is devoid of the inertiality phenomenon. They have a burner where they dose wood granules; practically instantly, the flame goes out when the supply is cut off.

The risk associated with inertiality is that the water heater may overheat and boil its coolant. High pressure from the formation of steam tears the unit body and a portion of the supply pipeline. Consequently, the furnace room is overflowing with water, producing copious amounts of steam, and the solid fuel boiler is no longer fit for use.

An analogous circumstance could transpire if the heat generator is incorrectly strapped. Actually, the maximum efficiency of a wood boiler occurs during its normal operating mode; this is when the unit operates at its peak efficiency. Вогда термостат реагирует на достиѶение теплоносителем температуры 85 °С и прикрывает воздушную заслонку, горение и тление в топке еще продольается. Before it stops growing, the water’s temperature must rise by an additional 2-4 °C, or even more.

A security group is always involved in the strapping of a solid fuel boiler in order to prevent excess pressure and the ensuing accident; this will be covered in more detail below.

Condensate that forms on the fuel’s inner walls as a result of the coolant’s unheated water shirt passing through it is an additional unfavorable aspect of the aggregate’s operation on wood. This condensate is not at all God’s dew because it is an aggressive fluid that causes the burning chamber’s steel walls to corrode rapidly. After combining with ash, the condensate becomes sticky and difficult to remove from the surface. The installation of a mixing unit within a solid fuel boiler’s outline solves the issue.

This plaque lowers a solid fuel boiler’s efficiency by acting as a heat insulator.

It’s premature to let out a sigh of relief on your own. Another issue they may encounter is the potential for temperature shock to destroy cast iron. Imagine that the electricity and circulation pump in a private home were turned off for twenty to thirty minutes, causing the water to drain from a solid fuel boiler. Because of the same inertia, the water in the heat exchanger heats up during this time and manages to cool in the radiators.

The pump activates, electricity appears, and coolant from a closed heating system is sent to a heated boiler through the pump. A temperature shock happens from the heat exchanger’s abrupt temperature difference, a cast-iron section cracks, and water spills to the floor. It is extremely difficult to fix, and replacing the section isn’t always an option. Thus, in this case, the admixture knot will avert an accident—which will be covered in more detail later.

The purpose of describing emergency scenarios and their outcomes is not to terrify solid fuel boiler owners or persuade them to purchase needless components of austerity plans. Practical experience, which is the foundation of the description, must always be considered. The likelihood of such outcomes is incredibly low when the thermal unit is connected correctly—nearly the same as with heat generators powered by other fuel types.

How to connect a solid fuel boiler

Two key components are included in the standard diagram for connecting a solid fuel boiler so that it can operate dependably in a residential heating system. As seen in the figure, this security group and mixing node is built around a three-way valve with a thermogol and a temperature sensor.

Note: Since the expansion tank can be found in different locations within different heating systems, it is not shown here.

The unit should always be connected correctly as shown in the scheme, which goes with any fuel boiler—even pellet boilers. There are many different general heating schemes that you can find anywhere. Some of them include a heat accumulator, an indirect heating boiler, or a hydraulic shot; in all cases, this node is not shown but is required. The following is further explained in the video:

The security group, which is directly installed at the solid fuel boiler supplier’s output, is responsible for automatically dumping the network’s pressure when it rises above a predetermined threshold, which is typically 3 bar. This activates the safety valve, and in addition, the element has a manometer and an automated air vent. While the second helps to regulate the pressure, the first creates air that ends up in the coolant.

Take note! Installing locking reinforcement at the pipeline segment between the boiler and the security group is prohibited.

How the scheme works

Starting with the kindle, a mixing node that shields the heat generator from condensate and temperature variations operates in accordance with the following algorithm:

  1. Firewood only flare up, the pump is turned on, the valve from the heating system is closed. The coolant circulates a small circle through the bypass.
  2. With an increase in the temperature in the reverse pipeline to 50-55 ° C, where there is an end -of -line overhead overhead type sensor, the thermal head on its command begins to press the stem of the three -way valve.
  3. The valve slowly opens and cold water gradually enters the boiler, mixing from the hot from the bypas.
  4. As all radiators warm up, the total temperature grows and then the valve overlaps the bypass completely, passing the entire coolant through the heat exchanger of the unit.

This binding scheme is the most straightforward and dependable; you can safely install it yourself and guarantee the safe operation of a solid fuel boiler. In light of this, the following advice is advised, particularly when using polypropylene or other polymer pipes to strap a wood heater in a private residence:

  1. Make a pipe section from the boiler to the security group, and then lay the plastic.
  2. Thick-walled polypropylene poorly conducts heat, which is why the overhead sensor will openly lie, and a three-way crane-get delayed. For the correct operation of the node, the site between the pump and the heat generator where the copper flask is worth it should also be metallic.

The location where the circulation pump is being installed is another moment. He should ideally be standing on the return in front of a wood boiler, as shown in the diagram. Generally speaking, you can turn on the pump on the presentation; however, keep in mind the previously mentioned fact that steam might appear in the supply pipe during an emergency. The coolant circulation will cease as soon as steam enters the pump because it is unable to pump gases. As a result, the boiler’s potential explosion risk will increase because the return water flow will not be sufficient to cool it.

The method of reducing the strapping

Installing a three-way mixing valve with a simplified structure that eliminates the need to connect the thermal car and overhead temperature sensor can reduce the condensate protection scheme. It already has a thermostatic element installed, set to the mixture’s fixed temperature of 55 or 60 °C, as seen in the figure:

Herz’s unique three-way valve for solid fuel heating units-Teplomix

Note: There are numerous well-known brands of similar valves, such as Herz Armaturen, Danfoss, Regulus, and others, that support the fixed temperature of mixed water at the output and are made to install a solid fuel boiler in the boiler’s primary contour.

Installing such an item undoubtedly enables you to save money on a tt-kotla stray. However, at the same time, the coolant’s temperature deviation at the output can reach 1-2 °C, and the option to adjust it with a thermal cutter is gone. These shortcomings are usually negligible.

Binding option with buffer capacity

For this reason, having a buffer container is very desirable when using a boiler that burns solid fuels. The unit must operate in maximum mode in order to operate efficiently and generate heat at the passport’s efficiency level (between 75 and 85% of various types). Оогда прикрывается воздушная заслонка с целью замедлить горение, наблюдается недостаток кислорода и КПД сжигания дров снижается. In this scenario, atmospheric carbon monoxide (CO) emissions rise.

As a point of reference. The majority of European countries have banned solid-fuel boilers without buffer capacity due to emissions.

On the other hand, modern heat generators’ coolant reaches 85 °C when burning at maximum capacity, and a single firewood lay only takes four hours by four. For many private home owners, this is not ideal. The buffer container can be used as a tank accumulator by being inserted into the tt-boiler strapping. This is the solution to the problem. It appears as follows:it appears as follows:

By taking measurements of T1 and T2, you can set up the container’s layout to include a balancing valve.

When the firebox burns with maximum intensity, heat (or loads, to use the technical term) is accumulated in the buffer container and then transferred to the heating system after attenuation. Conversely, a second pump and a three-way mixing valve are also installed from the accumulator tank to regulate the temperature of the coolant supplied to the radiators. Since the furnace will provide a buffer capacity after attenuating, there is no longer any need to run to the boiler every four hours. The volume and heating temperature determine how long it will take.

As a point of reference. Based on real-world experience, the heat accumulator’s capacity can be calculated as follows: a private residence with 200 m² of area requires a tank with a minimum volume of 1 m³.

There are a few significant subtleties. A solid fuel boiler that can simultaneously heat and load buffer capacity is required for the safe operation of the strapping scheme. Thus, two times as much power is required as predicted. An additional consideration is choosing the pump performance so that the boiler circuit’s flow rate marginally surpasses the volume of water flowing in the heating contour.

Our expert in the video presents an intriguing alternative for connecting TT KOTLA without a pump using a homemade buffer reservoir (which doubles as an indirect heating boiler):

Joint connection of two boilers

Many private home owners install two or more heat sources that use various energy sources to improve the comfort of their heating. Currently, the most pertinent boiler combinations on:

  • natural gas and firewood;
  • fuel and electricity.

In light of this, the gas and solid fuel boilers need to be linked such that, upon burning the next piece of firewood, the second boiler takes over for the first. The same specifications apply when strapping an electric boiler using wood. When a buffer container is involved in the strapping circuit, as illustrated in the figure, it simultaneously functions as a hydraulic shotgun, making this very straightforward.

As you can see, two separate boilers can serve multiple heating distribution contours simultaneously—batteries, warm floors, and load an indirect heating boiler—thanks to the presence of an intermediate tank-accumulator. However, due to the high cost, not everyone installed the heat accumulator with TT KOTLOL. Here’s a straightforward plan that you can install with your own hands:

It should be noted that the plan is equitable for both electric and solid fuel-fueled gas heat generators.

Here, a wood heater serves as the primary heat source. Following the firewood laying, the house’s air temperature starts to drop, which triggers the room thermostat’s sensor to turn on the electric boiler heating right away. When the feed pipe’s temperature drops without fresh firewood being loaded, the solid fuel unit’s overhead mechanical thermostat cuts the pump. Should it be lit after a while, then the sequence of events will be reversed. The following joint connection method is explained in detail in the video:

Binding method by primary and secondary rings

To guarantee a large number of users, there is an additional method of sharing a solid-fuel boiler with an electric boiler. With the help of primary and secondary circulation rings, it is possible to separate flows hydraulically without the need for a hydraulic rifle. In addition, even though the circuit may seem complicated, the system can operate reliably with a minimum amount of electronics, and no controller is necessary:

The trick is that one main circulation ring of the supply pipeline and the reverse are connected to all consumers and boilers. The pressure drop is negligible when compared to the pressure of the main circuit pump because of the short distance (up to 300 mm) between the connections. Because of this, the flow of water in the primary ring is independent of the secondary rings’ pumps. The coolant’s temperature is the only variable.

It is theoretically possible to incorporate as many secondary rings and heat sources into the main circuit. The performance of the pumping units and the proper selection of pipe diameters are crucial. In the most "voracious" secondary circuit, the main ring pump’s actual performance should outperform its consumption.

In order to accomplish this, a hydraulic calculation must be made; only then will it be feasible to choose the pumps appropriately, so expert assistance is required. Furthermore, disconnecting thermostats must be installed in order to connect the operation of electric boilers and solid fuel boilers, as detailed in the following video:

Materials Needed Polypropylene piping, fittings (elbows, tees, connectors), fasteners (screws, nails), insulation (if necessary)
Tools Required Drill, screwdriver, wrench, pipe cutter, measuring tape, pencil, level, insulation cutter (if needed)

There are many benefits to strapping a solid fuel boiler with polypropylene piping for homeowners who want to increase the sustainability and efficiency of their heating systems. The longevity and corrosion resistance of polypropylene pipes are two of the main advantages. The longer lifespan of the heating system is ensured by the fact that polypropylene is not prone to rust or degradation from exposure to moisture and chemicals, unlike traditional metal pipes.

Polypropylene piping also has the important benefit of being flexible, which makes installation easier and makes it easier to navigate around obstacles in the house. Because of its flexibility, the heating system’s components connect more seamlessly and there is less chance of leaks due to the need for fewer fittings and joints. Polypropylene pipes are also lightweight, which facilitates handling and transportation during installation.

Moreover, polypropylene is a superior insulator, reducing heat loss and raising the heating system’s overall efficiency. Homeowners can optimize their energy usage and gradually reduce their heating costs by minimizing thermal bridging and heat transfer through the pipes. Furthermore, the smooth interior surface of polypropylene pipes reduces friction, enabling higher flow rates and enhanced heating system performance.

By lessening the heating system’s environmental impact, strapping solid fuel boilers with polypropylene piping not only makes sense, but it also contributes to sustainability objectives. Because polypropylene is recyclable, it can be used again rather than ending up in a landfill when its useful life is coming to an end. Additionally, utilizing polypropylene piping results in increased energy efficiency, which reduces carbon emissions and lessens the environmental impact of heating homes.

In conclusion, for homeowners looking to increase the effectiveness and performance of their heating systems, strapping a solid fuel boiler with polypropylene piping offers an affordable, long-lasting, and sustainable solution. Polypropylene piping offers a workable and long-term solution for efficiently heating homes while reducing energy consumption and environmental impact because of its resistance to corrosion, flexibility, insulating qualities, and environmental advantages.
