PURPOSE:To enable a non-azeotropic mixture medium to be used as working medium without inducing any decreasing in thermal accumulated temperature by a method wherein an upstream side of a condenser of a heat pump is positioned at an upper side of a flow path and a downstream side of the condenser is positioned at a lower side of it, hot water is introduced from a bottom part of the condenser into a flow path and then overflow from the upper part of the flow path into a hot water storing tank. CONSTITUTION:A hot water feeder is provided with a flow path 8 divided by an interior of a hot water accumulator tank 7 in which a circumference of a condenser 4 of a heat pump 1 acting as a heat source is enclosed by a partition wall 9. The flow path 8 is provided with an overflow port 11 for communicating with an interior of the hot water storing tank 7 at an upper end, and a water feeding pipe 12 is connected to a water feeding port 10 at a lower end. As a hot water of low temperature is flowed into the flow path 8 from the water feeding port 10 at the bottom part of the flow path, it exchanges heat with the downstream side of the condenser 4 of the heat pump 1, i.e. a final condensation temperature and then the water moves upwardly within the flow path 8 while being gradually heated, exchanges heat with a hot condensation side at the upper part of the flow path and reaches the desired temperature, thereafter it is overflown into the hot water storing tank 7. That is, as the condensation is proceeded, temperature of the fluid to be heat exchanged is also increased as the condensation temperature of the working medium of which temperature is varied, so that the temperature of stored heat is not decreased. |
