<p>A heat pump heater (100) includes a heat pump (101), a heat transfer circuit (107), a heat utilization device (109), a flow regulator (108), and a controller (110). A heat medium heated by the heat pump circulates in the heat transfer circuit. The water circulation rate can be changed by an inverter pump (108). The controller (110) controls the heat pump (101) to allow the heat utilization device (109) to produce a required heating output, and controls the flow regulator (108) to prevent a return temperature from rising with a rise in a supply temperature.</p> |
