What is a solid fuel boiler?

Note! This is a unit for heating the coolant in the heating circuit, which generates thermal energy by burning fuels such as coal, wood, peat, etc.

Solid fuel boilers have found their application in private homes and in production. They are are distinguished by high efficiency and have a high safety class.

More expensive models are equipped with automatic control systems, cheaper designs are controlled manually.

What parameters to pay attention to when choosing?

When choosing such a device, you need to pay attention to a number of important factors:

  • type of fuel loading.
    Distributed manual loading through the loading door or automatic using a special mechanism;
  • heat exchanger material.
    The latter are made of steel (strong, with good resistance to thermal shocks, heat up quickly, but cool down quickly) or cast iron (corrosion resistant, retain heat excellently, but have an impressive weight and are vulnerable to temperature changes);
  • type of fuel used.
    These are firewood with not the highest efficiency, coal with the longest burning time, pellets and briquettes from various materials with certain pros and cons.
    Many boilers run on mixed fuels, these models are the most versatile;
  • fuel combustion method.
    There are boilers with natural (they work on the principle of a conventional furnace) and additional draft (equipped with a fan that additionally supplies air to the furnace).
    There are also pyrolysis devices equipped with a complex combustion mechanism, in which the fuel in the primary chamber burns in a low oxygen environment and at the same time releases a combustible gas that ignites in the secondary chamber;
  • long burning boilers.
    This is a separate category of devices where combustion proceeds longer and more evenly due to a number of engineering and technical solutions;
  • thermal power.
    The heater should be chosen with a margin of power, since in addition to heating, it will heat the water in the system.

When choosing a boiler you should not discount the volume of the loading chamber, the features of connecting the device to the chimney and the heating system circuit, the presence or absence of automation, auto-loading of fuel, the cooking zone.

Note! Additional options increase the cost of equipment, but provide greater comfort and ease of use of the boiler.
