<p>PURPOSE:To enable a sufficient amount of fed-out hot water to be attained even under a low hot water temperature by a method wherein a hot water feeder is provided with a heating tank installed in a hot water storing tank and supplying hot water to a supplying part and with a cold water mixing means for mixing the hot water fed from the hot water storing tank with the cold water fed from a water supplying source and supplying the mixed water to the heating tank. CONSTITUTION:A hot water feeder is provided with a hot water storing tank 1 for use in storing preliminary heated hot water, a heating tank 2 installed in the hot water storing tank 1 and for supplying hot water to a supplying part 13, and a fed water mixing means 3 for use in mixing hot water fed from the hot water storing tank 1 with water fed from a water supplying source (a) and supplying it into the heating tank 2. A cylindrical heating heater 14 having a water flowing passage 14a is installed in the heating tank 2, an outer surface of a heating heater 14 is provided with a heating surface 14b so as to heat the flowing water passing through a heating passage 15 between the heating surface 14b and the heating tank 2 and then the hot water is got. The hot water supplied from the supplying part 13 is mixed with the hot water in the hot water storing tank 1 preliminary heated and water fed from the water supplying source (a), they are further heated in the heating tank 1 and supplied, so that in winter season, even if the water temperature of water fed from the water supplying source (a) is low, a sufficient amount of fed-out hot water and temperature can be attained.</p> |
