Abstract (en)
[origin: EP2980504A1] A water heater includes: a heat medium circuit 4 in which a lower portion and an upper portion of a tank 11 storing heat medium therein are annularly connected to each other through a heat medium pipe; a heating device 30; a pump (14, 31); and a hot water supply circuit 16. The water heater includes a hot water supply heat exchanger 13 which exchanges heat between the heat medium flowing through the heat medium circuit 4 and the water flowing through the hot water supply circuit 16. Since the heat medium circuit 4 is a closed circuit, it is possible to use water including much hard component. It is possible to heat the heat medium and to heat water supplied to the hot water supply terminal by the single heat medium circuit 4. Therefore, it is possible to reduce the water heater in size and cost.
