A subatmospheric heating system refers to the field of heat power, namely energy-saving technologies and is designed for autonomous heating of residential, public, industrial buildings and greenhouses, livestock farms, etc.

For highly efficient transfer of heat flow from the heat energy source, a vacuum-steam method of heat transfer is used in an environment with adjustable depth of dilution with separate condensate return and vacuuming devices, with the possibility of mounting the heat point in either the basement, floor and roof variants. The reliability of the system is ensured by its safe and uninterrupted operation, and in the case of an unsatisfactory level of airtightness of the system (to eliminate leakages).

The energy efficiency of a subatmospheric heating system is achieved by a high rate of heat transfer and a minimum consumption of electricity by periodically operating pumps, while the efficiency of the system is 88% with energy savings of up to 40%
