Abstract

PURPOSE:To prevent the temperature of hot water at an upper part of a hot water storing tank from being lowered even at the time of a defrosting operation and prevent the temperature of hot water supplied from being lowered, by transferring heat between the hot water storing tank and a hot water supplying heat exchanger through water contained in a lower part of the tank. CONSTITUTION:The hot water supplying heat exchanger 5 and the hot water storing tank 4 are connected to each other by a circulating passage 6 in which a circulating pump 7 is intermediately provided, thereby constituting a heater 8 wherein heat generated at the heat exchanger 5 is given to circulating water to heat water contained in the tank 4. At the time of a defrosting operation in a hot water supplying operation, hot water to be fed from the tank 4 flows out through an outflow port 6a provided at a lower part of the tank 4, is deprived of heat at the heat exchanger 5 to become low-temperature water, which is returned to the lower part of the tank 4 through an inflow port 6b, and this cycle is repeated. Accordingly, although the temperature of hot water at the lower part of the tank 4 is lowered, the temperature at the upper part of the tank 4 is substantially constant without being lowered, so that the temperature of hot water supplied through hot water supplying cocks 13... can be maintained at a high temperature.
