Heating of cottage or suburban housing of any type predominantly tends to use equipment that does not depend on expensive energy sources. With the development of technology for the production of solid fuel boilers for heating private houses, which can now provide heat for a long time from one bookmark, they have become effective, economical and convenient when compared with other types of heating equipment.
The use of solid fuel boilers for heating private houses has become in demand again.

Benefits of using solid fuel boilers
The benefits of using a long-term heat-giving solid fuel heating boiler for a private house is valuable in that already at the installation stage it removes the most complex and expensive tasks. Just one connection to gas at home costs users much more than the cost of any solid fuel equipment. And if you consider that for this money you can buy a boiler that produces heat for half a day from one tab of solid inexpensive fuel, then such equipment fully pays for itself in one fuel season. The TT boiler allows you to relieve yourself of the burden of paying for the constantly rising gas price.
Scheme of work solid fuel boiler
A solid fuel boiler for heating a private house can be loaded with all available types of fuel: wood, peat, coal. Recently, the use of special pellets made from sawdust or straw is gaining popularity as solid fuel. Such an environmentally friendly, clean energy source is in itself capable of providing even higher efficiency of heat energy output. Maintenance of modern fuel equipment does not require time-consuming and frequent maintenance. It is enough to load it with fuel several times a day (it depends on the type of boiler).
Solid fuel boilers can operate on wood, coal or special fuel pellets (pellets)
Types of solid fuel boilers for heating private houses
This list is small, which allows anyone to easily determine which boiler is best suited in terms of purchase costs, maintenance and general feasibility. Solid fuel boilers for heating a private house are classic and pyrolysis.
The internal structure of a solid fuel boiler
Solid fuel boilers conventional
If we talk about this type of fuel equipment, then these are traditional boilers that have the simplest design.Fuel burns in a conventional manner, heating water, which carries heat throughout the home. The advantage is that the price of a solid fuel boiler for heating a private house will be low. Among the disadvantages are the following: loss of released energy, the need to often lay fuel.
The modern design of solid fuel boilers will allow them to fit into any living space
If earlier, when the technologies of efficient fuel boilers were not used for private use, it was the most used equipment. It can currently be purchased for country houses, where a short stay is planned during the cold season.
Firewood is an affordable and economical fuel
Pyrolysis boilers
The design of solid fuel boilers for heating a private house of the pyrolysis type has its own characteristics. The tank where the fuel is burned is divided into two parts. The chamber where solids are loaded is located in the upper half. The air supply is regulated in such a way that it is sufficient to support the combustion process. As a result, gas is released, which can also burn. He heads to the lower chamber. The efficiency of the firebox of a pyrolysis boiler increases by 80-90%, and the burning time of one tab can be up to 12 hours.
Construction of a pyrolysis solid fuel boiler
The compartment in which the gases are burned must withstand high temperatures. Therefore, it is manufactured using heat-resistant materials. After fuel combustion in pyrolysis colas, there is practically no ash and soot left. The complex design, the need to use special materials, install a smoke exhauster, electronic control systems determine that the price of solid fuel boilers for heating a private house is much more expensive than classical ones. But the benefits speak for themselves.
Stages of work of a solid fuel pyrolysis boiler
Despite the high cost, pyrolysis boilers do not alienate buyers. They know how to count money and can determine the benefits that will pay off all the costs in the short term. Therefore, the present and the future in the process of organizing heating of private houses, associated with pyrolysis boilers.

Disadvantages of using solid fuel boilers
The main one, and it can rather be called not a disadvantage, but an inconvenience, is the need to load with fuel from time to time. Depending on the type of boiler, such actions can have a different frequency - from two to six times a day. Also, the equipment requires regular maintenance associated with the removal of spent fuel. If this is not done, a solid fuel boiler for heating a private house will become less efficient or stop functioning.
The solid fuel boiler must be periodically filled with fuel - wood, coal, peat or special pellets
Heat is not supplied immediately after starting. It may also be difficult to light it up after a long period of inactivity. It is possible to regulate the heat supply, but it is less controllable than, say, gas boilers... It is also impossible to immediately stop the operation of the boiler. It stops heating after all the fuel loaded into it burns out. Firewood, coal or peat must be stored somewhere. It must be dry and close to the boiler. Solid fuels are a source of dust and debris. Despite this, all these are solvable problems that do not interfere with making the house warm and cozy.

Choosing a solid fuel boiler
In order to choose a convenient and efficient boiler once and for many years, it is necessary to calculate the power required for heating the premises. In a building where the correct insulation measures have been carried out, and the ceiling height does not exceed three meters, the heat transfer rate of the boiler is determined at the rate of 1 kW per 10 m² of the area.
The choice of a solid fuel boiler is influenced by the area of the heated room, the presence and type of wall insulation, individual climatic conditions
It is also necessary to take into account other factors: the required average temperature in the room during the coldest season, the number of windows, their location, the length of the outer walls, etc. Taking into account all the features will help you choose the most optimal solid fuel boiler for heating a private house, the price of which will meet the needs and capabilities of the system.

Installing a solid fuel boiler
Heating boiler it is recommended to install it in a separate room. This will isolate the equipment from children's access and will also increase the safety conditions at work. The place of direct installation is filled with a concrete screed. Considering the heavy weight of the boiler, which will press on a small surface area, the thickness of the support should be at least 0.7 meters. There must be no gap between the bottom of the boiler and the base. If it does appear, then it is necessary to fill this space with a heat-resistant sealant.
The best option for placing a solid fuel boiler is a separate room - a boiler room. Often boiler rooms are located in the basement (basement) floors of the building.
Conclusion
Solid fuel boilers for heating a private house is still a popular, affordable and reliable source of heat in private homes. It can be the main or auxiliary heater in the system. Modernized and improved solid fuel equipment is a strong competitor to gas boilers. In those settlements where there are no gas pipelines, there is simply no real equivalent alternative to them.
