Installation supplying hot water for washing in domestic uses, uses heating of material that solidifies and melts at round the temperature required of hot water, and passes cold water directly through coils immersed in this material

摘要

The water heater passes cold water (1) through coils (4) inside the reservoir (5) of a heat exchanger. The heat exchanger is filled with a material that solidifies and melts at temperature corresponding to the temperature at which the heated water is to be delivered. A separate closed circuit (7) allows reheating of the heat transfer material.
