FIELD: heating.
SUBSTANCE: claimed invention relates to design of devices for combustion of fuel natural gas in order to obtain heat energy in form of hot water for heating and water for hot water supply. Claimed design can be used in industrial and civil construction for heating and hot water supply, in independent mobile and stationary objects at generation of heat energy due to combustion of fuel gas. Technical result is achieved by using automatic blowing of inlet of pressure sensor in pressure pipe by water jet, supplied through additionally installed blowing nozzle, and automatic discharge of contaminated and contaminated water through discharge valve into settler, located outside the boiler circuit, with automatic simultaneous recovery of losses of dumped water due to supply of pure water.
EFFECT: task for solution of which is aimed at the declared design is improvement of reliability and prevention of emergency situations related to heating pipes freezing.
