FIELD: heating.
SUBSTANCE: heating system with natural circulation comprises pipeline-joined heat generator connected with a pipeline of heated working medium discharge to an expansion tank and at least one heating device connected at one side with a pipeline of heated working medium supply and at the other side - with a pipeline of cooled working medium discharge connected with a heat generator. At the same time the expansion tank is connected to a pipeline of heated working medium supply to a heating device and is equipped with a pipe and float installed in it and tightly joined with a pipeline of heated working medium discharge from the heat generator with a capability of vertical displacement, besides, the outlet opening of the pipe is installed above the working medium level.
EFFECT: higher efficiency ratio of a heating system with natural circulation of coolant due to supply of a more heated coolant into a heating device.
