Abstract

PURPOSE:To prevent hot water from being instantaneously supplied previously and to obtain excellent feeling of use by connecting a mixing water pipe from a mixing valve at the lower part of a hot water storage tank to the lower part of a hot water supply pipe. CONSTITUTION:When a water valve 5 is opened, water is introduced into a mixing valve 7 where the quantity of water allowed to flow to a tank supply water pipe 9 and that allowed to flow to a mixed water pipe 10, are distributed. When the water stop valve 5 is opened, an electric control part 17 acts to open a tank water supply pipe valve 15 and a mixed water pipe valve 16, and water flows. Water which has flowed to a tank supply water pipe 9 enters the lower part of a hot water storage tank 2, and hot water is pushed out from the upper part of the hot water storage tank 2 to a hot water supply pipe 12. On the other hand, water which has flowed to a mixed water pipe 10 is introduced to the lower part of the hot water supply pipe 12 and is mixed with hot water which has flowed from the upper part of the hot water supply pipe 12, and is heated to a suitable temperature and supplied through a cock 12. Every time the water stop valve 5 is opened, water from the mixed water pipe 10 surely flows to the cock in advance because water has a distance shorter than hot water flowing from the upper part. When the stop valve 5 is closed, the tank water supply pipe valve 15 and the mixed water pipe valve 16 are closed, no water within the hot water storage tank 2 is extracted through a cock 11.
