How to correctly make the strapping of a solid fuel boiler

Having the proper heating system is essential to keeping your house warm and comfortable during the winter. Since they provide effective warmth and frequently result in cost savings when compared to alternative heating methods, solid fuel boilers have long been a popular option for heating homes. However, for maximum efficiency and safety, make sure your solid fuel boiler is piped correctly.

A solid fuel boiler must be piped properly, which requires a number of crucial actions and considerations. To get the best results, attention to detail is essential, from choosing the appropriate piping materials to making sure that sizing and layout are correct. The fundamentals of proper piping must be understood whether you’re upgrading your current system or installing a new boiler.

Choosing the right piping materials is one of the first steps in plumbing a solid fuel boiler. The pipes need to be resilient to both the corrosive effects of burning solid fuels and high temperatures. Boiler piping is frequently made of copper, stainless steel, and steel. It’s important to carefully consider your options because each material has pros and cons of its own.

An additional crucial component of boiler piping is appropriate pipe sizing. Smaller-than-expected pipes can impede the flow of steam or hot water, decreasing efficiency and possibly damaging the boiler. On the other hand, excessively large pipes may cause energy loss and heat loss. For best results, the right pipe size must be determined using variables like boiler output, distance, and flow rate.

The layout of the piping system is critical to its effectiveness, in addition to choosing the appropriate materials and sizing the pipes. In order to guarantee effective heat transfer and low heat loss, the pipes must be arranged. In colder climates, proper insulation is also necessary to keep heat from escaping and to guard against freezing.

All things considered, installing a solid fuel boiler correctly necessitates rigorous planning, close attention to detail, and compliance with safety regulations. Your home can be kept warm and comfortable for many years to come with a dependable and efficient boiler if you make the proper material selections, size the pipes appropriately, and create an effective layout.

Options for piping a solid fuel boiler

Type of coolant circulation.
Type of heating system.
Simultaneous use of radiator heating and underfloor heating system.

The parameters and thermal properties of the heating system are impacted by the strapping selection, so choosing an appropriate plan should not be rushed.

Differentiating between the following schemes is customary based on the type of coolant circulation:

Strapping of a solid fuel heating boiler with forced circulation – the system requires the use of a circulation pump that pressurizes the water circuit. The advantage of this scheme is the uniform heating of all areas of heating, regardless of the distance from the boiler.

The disadvantage – the need for careful observance of angles and slopes of pipes, as well as, the possibility of application exclusively in radiator heating.

It is common practice to split a few more schemes based on a comparable feature in addition to the distribution of systems based on the coolant circulation type:

Open system – circulation is carried out naturally or with the help of a circulation pump. In this case, there is no pressure in the water circuit. Scheme of piping of a solid fuel boiler with an open system, complete with an expansion tank of an open type.
Closed system – connection of solid fuel boiler to a closed heating system, is carried out with the use of expansion tank membrane type, which maintains stable pressure parameters in the water circuit.

Several more widely used heating schemes can be distinguished based on their device or connection principle:

Strapping solid fuel boiler in a single-pipe system – in this case, the supply of coolant is carried out sequentially. The heated liquid flows from radiator to radiator, gradually cooling down. To the last battery is connected to the return pipe, through which the cooled coolant returns to the boiler. The advantage of a single-pipe solution is to reduce the cost of installation work and aesthetic appearance (pipes can be hidden in the wall or floor). The disadvantage, is the uneven heating of the water circuit.

Piping from the solid fuel boiler on the house by the two-pipe method, requires large material costs for the purchase of building materials.

Solid fuel boilers can be piped using contemporary systems that employ collector groups and hydrostrelka. If connecting water circuits using the principle of high and low temperature heating is the goal, then such solutions are employed. The warm flooring heating system has Hydrostrelka installed.

Consider the following factors when selecting a solid fuel boiler heating system:

Cost of piping.
Thermal characteristics of the room.

See a heating engineer for competent advice when calculating and choosing a suitable piping scheme.

Scheme of piping without heat accumulator

One of the most important considerations when selecting a solid fuel heating boiler pipework method is the existence of a heat accumulator. The heating system is constructed using the small and large circles of the heating system if a buffer tank is not available. The following guidelines are followed when installing a small circle:

Immediately after the boiler, a safety group is installed on the heating system supply.
Literally, after 1.5 m of the pipeline, install a tee-piece. A pipe is used to connect the supply and return of the heating system.
A wedge-shaped valve is installed on the connecting pipe, to control the intensity of the coolant circulation through the small heating circle.
On the return is installed three-way mixing valve, connected to the pipe connecting the supply and return.

This scheme’s operating principle is as follows:

After switching on the boiler, the heated coolant circulates through the small heating circle. A three-way valve prevents cold, not warmed water from entering the heat exchanger. A big difference in temperature between the supply and return leads to the boiler "crying". A large amount of condensate is formed, which negatively affects the heat exchanger.
The heating medium gradually warms up and after heating above 60°C, the three-way valve is opened. From this moment, the big circle of the heating system starts to work.
The small circle of the heating system, continues to function as a sub-mixture node, preventing boiling of the coolant, and reducing the gap between the temperature on the supply and return.

Bundling with indirect heating boiler

The solid fuel boiler pipe scheme with a buffer tank is a little different from the earlier choice. The buffer tank, also known as the indirect heating boiler, is actually just a regular thermos where water is heated and kept for specific uses.

This straightforward strapping solid fuel boiler, which is constructed as follows, replaces a small heating circle and has a tank heat accumulator.

The tank is installed between the boiler and the heating system.
The supply pipe is connected to the upper part of the boiler and the return pipe to the lower part.
Two circulation pumps are installed on the return flow. The capacity of the pumping equipment should be different. Settings are set so that the movement of coolant in the buffer tank, carried out from top to bottom. This can be achieved by putting a circulation pump of higher capacity before the storage tank, and less, after it.

There are numerous crucial purposes served by the piping connecting an indirect heating boiler to a solid fuel boiler.

Reduces the temperature difference between the supply and return of the heating system.
It allows to accumulate the received heat and add hot water to the heating system, after burning wood in the boiler.

In Western countries, the standard connection for a solid fuel boiler is an indirect heating boiler strapped to it. The program is not very well-liked among domestic consumers since it is rather expensive to buy and install the required hardware.

Tt boiler strapping together with an electric boiler

The basic plumbing layout, which combines the tt unit with the installation and simultaneous use of electric boilers, is highly well-liked. This solution has the benefit of allowing the use of an inexpensive solid fuel boiler. Additionally, an automatic switch to electricity is made if there is no way to add more fuel to the furnace after the wood or coal has burned.

The following is how the piping is done:

Two boilers are connected in parallel.
A circulation pump is installed in the electric boiler. For a solid fuel unit, pumping equipment will need to be installed.
To prevent the occurrence of a duplicate flow of coolant, when two circulation pumps are switched on at the same time, a special valve blocking the flow is installed. In this case, the check valve in the heating system is necessary to ensure that the simultaneous operation of two boilers, there is no stagnation of coolant in the boiler circuit. Two fittings will need to be installed. One valve is installed on the supply pipe from the electric boiler, the second, on the return, going to the solid fuel boiler.
Two temperature sensors will ensure the operation of the system. A room sensor is connected to the electric boiler. When the temperature in the rooms drops below the set minimum, the heating medium is automatically heated by electricity. In order to prevent heat loss, the pump for tt boiler is also equipped with a temperature sensor, which switches off the circulation of the coolant when the furnace chamber cools down.

To ensure efficient heating and insulation for your home, it"s crucial to have a well-designed piping system for your solid fuel boiler. The correct piping setup not only optimizes the performance of the boiler but also enhances the overall heating efficiency of your house. Start by carefully planning the layout of the pipes, considering factors like the location of radiators, the distance from the boiler, and the insulation of the pipes themselves. Proper sizing of the pipes is essential to maintain adequate water flow and prevent energy loss. Additionally, make sure to use high-quality materials that can withstand the heat produced by the boiler and resist corrosion over time. Regular maintenance and inspections are key to ensuring the longevity and effectiveness of your piping system, so don"t overlook these crucial steps in keeping your home warm and comfortable.

What pipe to do strapping a solid fuel boiler

The type of pipe that can be used for boiler piping is not strictly governed by regulations. Regarding the practical experience of operation, there is just one recommendation.

The portion of a tiny heating circle created by using copper or steel pipes. This prevents the pipes from spoiling and maintaining their tightness under the influence of high temperatures in the event of coolant boiling or an emergency. The remaining pipeline’s material can be selected at will.

The most popular strapping choices are:

Metal-plastic – strapping with metal-plastic pipes, is characterized by simplicity and speed of installation. If you have the necessary tools, all the work is easy to do on your own. It is worth installing metal-plastic pipes only if the system provides for the presence of a buffer tank that reduces the likelihood of overheating of the coolant.
Copper – piping copper pipe, will provide maximum heat output of the heating system. The material can withstand temperatures up to 300 ° C, does not oxidize. The disadvantages are considered to be the high temperature of heating the surface of the pipe, as well as requirements related to the prohibition of fittings made of aluminum.

Proper piping solid fuel boiler polypropylene, requires that the supply and return section near the boiler, made of metal. After that, with the help of adapters, connect polypropylene. Use seamless material designed for heating systems (pipes for DHW are prohibited to use).

Metal pipes work better for strapping solid fuel boilers because the coolant frequently reaches the boiling point of the liquid when heated. However, using analogs is permitted because this option isn’t always feasible. One of the best and most dependable ways to tie the system is to use polypropylene with fiberglass in heating systems that use solid fuel boilers.

How and with what to insulate pipes

Merilon or any other insulator intended for this use is used to insulate pipes. PET with a big diameter is used for extra protection if the pipeline is buried, as in the case of a free-standing boiler room.

PET pipe guards against harm from machines. Insulation reduces heat loss and acts as a kind of protection against condensation and burns from unintentional contact with the pipes. Use binding wire or clamps to secure the insulation.

Necessary units and assemblies for piping of tt boiler

The chosen plan, the existence or nonexistence of a buffer tank, and other equipment will determine the full list of fittings needed to connect the boiler to the system. In a typical connection, the ensuing bonds are necessary:

Thermostatic or thermo-mixing valve – is necessary to stabilize the heating medium and prevent overheating and boiling of the latter.
Expansion tank – provided in any heating scheme. Membrane expansion tank is installed in closed systems with forced circulation of the coolant. In gravity schemes, an open tank is installed at the highest point of the water circuit.
Circulation pump – is installed in closed and open systems with forced circulation of liquid in the water circuit. Some solutions, such as the use of a buffer tank, two parallel connected boilers, requires the installation of two modules of circulation equipment at once.
Check valve – coordinates the direction of the heat flow of the fluid. It is used when connecting a membrane tank. Prevents duplicate flow when electric and solid fuel boilers are connected at the same time.
Collector – used for simultaneous connection of warm floors and radiators. Without a manifold, you can not do without a manifold when making a radiant heating system, when each heater leads to a separate pipeline. A manifold in the heating system is required for most modern heating schemes.
Air vent – an automatic valve included in the standard equipment of the safety group. In automatic mode, bleeds air from the heating system.
System make-up valve – controls the pressure and the total volume of the heating medium in the system. When it drops below the minimum value, it opens and supplements the water circuit with liquid.
System pressure sensor – also part of the safety group. Indicates the nominal pressure in the heating system, often the first to indicate overheating of the coolant. By checking the readings of the thermometer and pressure sensor (manometer), it is convenient to set the necessary operating mode and adjust the automatic draught regulator.

Coarse filter – installed on the return, just before the circulation pump. It is recommended that the filter is mounted before the buffer tank, expansion tank and other sensitive elements of the heating system.
Hydraulic arrow – hydraulic arrow in the heating system, needed for boilers using the principle of long burning and modulating power settings. Practically – this device replaces a buffer tank and has a common principle of operation.
Mixing unit or sub-mixing unit – mixes hot and cool water from the heating cohort to prevent boiling and reduce the difference between the supply and return of the coolant.
