Method for accumulating heat in container includes storing heat in first fluid in sealed container, transferring heat by condensing vapor phase of fluid on exchanger, and supplying heat to container

摘要

The hot water tank comprises a sealed container (1) in which heat is stored in water (2a,2b) at its vapor pressure. Heat is transferred by condensing (3) the vapor phase on the external surface (4a) of an exchanger located in this phase. Heat is supplied to the container by a heating resistor (5a). An Independent claim is also included for heat accumulating apparatus.
