Abstract
The article is dealing with studying an electric vacuum heater and a low-pressure steam electric heater developed on its basis. A low-pressure steam electric heater can be the basis of a new generation autonomous heating system. Prototypes of a low-pressure steam electric heater with an automatic control system for its operation modes have been developed. The prototype power is 600, 800, 1000 W. Reliability of the electric vacuum heater has been tested empirically. A low-pressure steam electric heater combines the efficiency of an electric coil and the comfort of heat from a traditional central heating radiator without the drawbacks of oil-filled electric radiators and is a reliable, fireproof electric heater.
