Abstract (en)

[origin: EP3199884A1] A hot-water supply and heating system capable of adequately increasing the temperature of hot water that flows into a hot water storage tank during a heat accumulating operation, in a configuration in which a single water pump is used for both the heat accumulating operation and an indoor-heating operation, is provided. The hot-water supply and heating system includes: a heat accumulating water path that connects a first water outlet 25 of a hot water storage tank 2, a water pump 11, a water heater 100, and a first water inlet 26 of the hot water storage tank 2 in this order; an indoor-heating water path that connects a second water inlet 28, the water pump 11, the water heater 100, and a second water outlet 27 from which water to be supplied to an indoor-heating device comes out in this order; and a switching valve 6 configured to switch between the heat accumulating water path and the indoor-heating water path. An overlap portion in which the heat accumulating water path overlaps the indoor-heating water path is provided. A pressure loss of the heat accumulating water path is higher than a pressure loss of the indoor-heating water path.
