HOT WATER SUPPLY SYSTEM USING BATH HEAT

摘要

PROBLEM TO BE SOLVED: To efficiently recover heat energy in the hot water remaining in a bathtub to save energy, and boil the whole water in a storage tank in a limited time such as in a time late at night to prevent shortage of the hot water.

SOLUTION: The hot water supply system using bath heat comprises: a heating means 14 disposed in an upper part of a hot water storage tank 1; a hot water supply pump 15 flowing the water from a lower part to the upper part in the hot water storage tank 1; a heat exchanger 16 disposed in a circulation circuit of the water supply pump 15; a bath heat exchanger 17 having the relation of heat exchange with the heat exchanger 16; and the bathtub 18 communicating with the heat exchanger 17. Therefore, heat energy in the remaining water in the bathtub can be efficiently recovered to save the energy.
