A hot water heating device according to the present disclosure includes a heat source machine, a hot water storage tank, a heating terminal, a circulating pump which circulates hot water between the hot water storage tank and the heating terminal, a mixing device which mixes the hot water to be conveyed from the hot water storage tank to the heating terminal with the hot water whose heat has been dissipated at the heating terminal, a temperature detector provided at a downstream side of the mixing device for detecting a temperature of the hot water circulating between the hot water storage tank and the heating terminal, and a control device. When the temperature detector detects a predetermined temperature or above, the control device stops driving of the circulating pump. This enables improvement in heat exchange efficiency as well as improvement in safety. |
