<p>A hot water supply device where heat energy remaining in warm water used fir a specific purpose, such as, for example, remaining bath water, can be used to heat water by using a simple structure. The hot water supply device causes water flowing out of the lower part of a hot water storage tank, heated by a gas cooler, to collect heat energy of remaining warm water in a bath tub. This eliminates the need for refrigerant, flowing in a refrigerant circuit of a heat pump unit, to collect the heat energy of the remaining bath water. Thus, the heat energy of the remaining bath water can be used to heat water by a simple structure of only piping for water flow.</p> |
