The vacuum steam heating system relates to the field of heat power, and specifically to energy saving technologies and is intended for autonomous heating of residential, public, industrial buildings and greenhouses, livestock farms, etc. In order to achieve the high-efficiency transfer of a thermal flow from a source of thermal energy, a vacuum steam method of heat transfer is used in conjunction of a closed evaporation-condensation cycle having a high rate of molar heat transfer via steam, with separate subsystems of condensate return and vacuum-creation and rarification control within the system, with the possibility of installing a heat supply point in a basement variant, floor-mounted variant and roof variant. The system reliability is achieved via the safe and uninterrupted operation, including in the presence of unsatisfactory levels of the system air-tightness (prior to eliminating leaks). The system efficiency reaches 89%, with 38% energy-carrier conservation.

Disclosed is a water system that generates heated water and distilled water. The water system has a boiler configured to boil water to produce steam. The water system also has a condensing conduit to receive the steam, wherein thermal energy is removed to condense the steam into distilled water and to cool the distilled water. A heat exchanger is thermally coupled to the condensing conduit to remove a first portion of the thermal energy. The heat exchanger has a heating conduit configured to receive water and to heat the water using the first portion of the thermal energy to produce heated water. According to an embodiment of the disclosure, the water system also has a heat remover thermally coupled to the condensing conduit to remove a second portion of the thermal energy thereby cooling the distilled water in the condensing conduit.

Embodiments are disclosed of a radiator temperature control apparatus for controlling the heat output of a radiator. The radiator temperature control apparatus may include an airtight enclosure around the air outlet of the radiator air vent, an adjustable opening in the airtight enclosure controlled by an actuator, and a controller connected to the actuator. In operation, the controller can be configured to open the adjustable opening in the airtight enclosure allowing air in the radiator to be expelled through the adjustable opening, thereby allowing steam to enter the radiator, and heat the room. The controller can be configured to close the adjustable opening, stopping air from being expelled from the radiator, thereby stopping additional steam from entering the radiator.

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%
