PURPOSE:To improve the heat exhange efficiency of a hot water supply pipe in a heat exchanger and make possible to reduce the size of a device as a whole by connecting heat exchange piping to the heat accumulating tank of heating medium heated by the solar heat and inserting the hot water supply pipe through the heat exchanging part. CONSTITUTION:This hot water supply device A has, roughly divided, heat accumlating piping 6, heat exchange piping 5, heating medium circulating pipeing 8 and a heat accumulating tank 2. The heating medium circulating piping 8 forms a loop, is provided with a circulating pump 9, a jet pump 10 and an opening and closing valve 11 in succession and is so arranged that low temperature water in the heat accumulating tank 2 may be flowed directly into the circulating pump 9. On the other hand, the entrance 12 of the heat accumulating piping 6 is connected to the barrel 13 of the jet pump 10 and heating medium is flowed to the piping 6 side directly when a blow switch 18 is turned off and the opening and closing valve 11 is closed. By installing a heat exchanging part 4 on the way of the heat accumlating piping 6 and inserting a hot water supply pipe 3 connecting to cocks 17 through the heat exchanger, the intended purpose is attained. |
