Abstract
When hot water supply and room heating are requested simultaneously, a hot water supply operation, by which energy saving is achieved without impairing the comfortability in a room, is performed. A heat-pump apparatus of a variable operation capacity type, a primary water circuit, a hot water tank, a room heater, and a controller are provided. The controller sets a hot water supply operation completion target time in the case of a requests for a simultaneous hot water supply and room heating operation, based on a temperature difference between the outdoor air temperature and the indoor temperature, and determines the rotation speed of the compressor in the hot water supply operation completion target time set.
