Abstract (en)

A hot-water heating apparatus includes a heater incorporating a heat pump cycle and a heating cycle in which hot water is circulated through the heater and a heating terminal unit, the hot water being obtained by heating water by the heater. The heating apparatus further includes a circulation pump circulating the hot water in the heating cycle, a circulation quantity detector configured to detect a quantity of the hot water circulated in the heating cycle, and a controller. A determiner determines a quantity level of the hot water circulated in the heating cycle and sends a result of the determined quantity level to a control terminal slave via a network.
