The search for alternative ways of obtaining heat energy and their technical realization in order to minimize production costs is conducted. It has been shown that for low energy and household needs, it is advisable and economically advantageous to use solar, wind energy or conventional solid fuel boilers, and for enterprises with higher energy needs such methods of heat supply are currently ineffective. The analysis of the methods of heat supply for large industrial or domestic premises, such as workshops of poultry farms, livestock farms, warehouses, greenhouses, swimming pools, sports complexes, recreation facilities, dryers, elevators, etc., in which long-term maintenance of a fixed temperature or water heating is required. It is established that conventional solid fuel boilers cannot be used to heat large objects due to the lack of capacity and high fuel moisture requirements. It is proposed to use solid fuel boilers of the new generation, so-called heat generators, for the production of which advanced technologies and know-how are used. The peculiarity of heat generators is the ability to use fuel with humidity up to 50 %, achieving high power by obtaining high temperatures for which not only the fuel but also the combustion products are burned. There is no need to install chimneys for these boilers, since clean, transparent gas is emitted outside, the practical and cost-effective use of which may be the subject of the further research. That is why such boilers are environmentally friendly. The cost-effectiveness and payback period for the use of thermal generators for several types of solid fuel have been calculated. It has been shown that, as compared to gas use, maximum efficiency of 78.5 % and cost savings of 6 times are achieved when used as aviary fuel that cannot be applied to conventional boilers due to high humidity. The relatively short payback period of the thermal generators within 1.3–2 years makes their investment attractiveness for large-scale implementation.
