Solid fuel boilers for heating a private house: the secrets of choosing and characteristics of individual models
Solid fuel boilers for heating a private house can operate on coal, wood, briquettes, peat or coke. Autonomous equipment does not depend on the electricity supply or the central gas line. Combined devices are popular that can operate from a primary and secondary source.

Solid fuel boilers for heating a private house: design features
Solid fuel units are made of durable steel or cast iron. These materials affect the service life and cooling rate of the structure. Steel models are resistant to temperature extremes and pressure. Cast iron is characterized by resistance to corrosion.
A long burning cast iron solid fuel heating boiler is suitable for houses with permanent residence. Its advantages include durability, unpretentious care and long-term cooling.
Steel appliances are characterized by easy loading, reasonable price and high aesthetics. The boilers are equipped with one or two circuits. Two rings allow not only heating the house, but also supplying hot water. Depending on the fuel combustion time, the equipment is divided into traditional and pyrolysis equipment.
Some models will charge fuel once a week. Pyrolysis structures are environmentally friendly, economical in fuel consumption and energy independence.

Chimney for a solid fuel boiler: the nuances of the arrangement
Certain requirements must be read before installation chimney for boilerbut on solid fuel. The installation conditions must be observed to organize a constant combustion process, as well as for the effective operation of the device. Most often, the chimneys of coal boilers are made of ceramics. They are able to withstand high temperatures and do not leave deposits on the smooth surface. The structure of this material is resistant to corrosion and condensation.
During the installation of the structure, parts of the duct, expanded clay concrete shell and a heat-insulating layer are used. Metal chimneys are made of durable steel, which is resistant to high temperatures and corrosion. Such an element consists of several layers. There is a layer of thermal insulation between the inner and outer shells. These chimneys are compatible with all types of boilers.
The following requirements are imposed on the arrangement of chimneys:
- the diameter of the chimney must correspond to the dimensions of the gas outlet;
- the structure must be installed in a strictly vertical position;
- in the presence of turning sections, special holes are provided for cleaning the chimney;
- a certain distance must be observed between the chimney and flammable structures;
- the head of the device is equipped with a spark arrester and a deflector.
Attention! The steel chimney must be equipped with a linear deformation compensator, which is needed to maintain the tightness of the bushing connections.
Strapping schemes
Choosing solid fuel boilers for heating a private house, it is worth considering the strapping scheme. Do not connect the unit directly to the heating circuit. As this contributes to the formation of condensation and the formation of deposits.
To organize the optimal operation of the equipment, you should use the following methods:
- installation of an expansion tank;
- installation of a safety group with an adjustable valve;
- installation between the unit and the tank-heat storage circuit;
- installation of a hydraulic circuit separator.
There are several strapping schemes that differ in the number of circuits or their complexity. What matters is the piping layout, as well as the ways of circulating the coolant.
Important! The boiler itself is piped only with metal pipes.
Models of solid fuel heating boilers for long burning
You can buy excellent domestic solid fuel boilers for heating a private house. By comparing the advantages and disadvantages of individual models, as well as their characteristics, you can choose the best option.
The advantages of boilers of the Pellet and Zota Mix model range include:
- high efficiency rate;
- combined steel models operate on any type of fuel;
- the ash container and the combustion chamber are located inside the water jacket;
- a chimney damper, air suction and a mechanical traction regulator installed in the furnace door provide complete combustion with low draft;
- the surface of the body is treated with an anti-corrosion compound;
- availability when performing repair work.
These models have certain drawbacks. A supply of fuel is required, as well as a place to store it. The structure is installed in a separate room. It is important to prepare special water for the boiler.
When choosing a solid fuel boiler with a water circuit, it is worth considering the AKTV devices, which are manufactured by Sibteploenergomash. Their advantages include:
- affordable price;
- compact size;
- ash drawer;
- the ability to connect to the heating piping;
- devices can operate on electricity and gas.
The disadvantages include primitive automation and outdated design.
Also worth considering pyrolysis solid fuel units Bourgeois from the TPP company.
It is worth highlighting the following advantages of this equipment:
- one bookmark is required to operate the equipment for 8 hours;
- low fuel consumption;
- the generator is suitable for forced and natural circulation systems;
- environmental friendliness of the unit.
Among the minuses, it is worth noting the complexity of installation, the need for manual bookmarking and significant weight.
Helpful information! For heating greenhouses, garages or country houses you can build structures with your own hands.
Price overview
An important parameter is the price. Solid fuel boilers for long burning, depending on the manufacturer and technical characteristics, may have different prices.
Helpful hints
When choosing a solid fuel structure, it is worth considering certain parameters:
- building area;
- distance to floors;
- climatic features of a particular region;
- the amount of heat loss.
Also, before buying equipment, you must select the type of fuel. This can be coke, peat briquettes, wood or coal.
It is worth considering the acquisition of a long-burning solid fuel double-circuit boiler, which will heat water in addition to heating. With a weak draft and a poor-quality chimney, it is worth choosing models with a fan. After clarifying all the important characteristics, you can proceed to the selection of a suitable design.
