The standard solution, so to speak, is the boiler.

The heating system of a country house consists of three parts. The first part is a generator or heat source. The second component — pipelines and heating devices. The third — elements of control and management of the system. In the practice of building suburban facilities, there are examples of when one, the general source of heat heats up several houses. As a rule, this is a boiler room, which is called a «stoker», or heating center. But such an approach to resolving the issue of heating is dictated by some external circumstances, and not just the desire of the developer. The standard solution, so to speak, is the boiler. Boiler — as an autonomous heat source in the house.
