Abstract

The oil level in a compressor is lowered upon activation of the compressor. A heat pump-type heating device of the present invention includes: a refrigerant circuit in which a compressor, a heat-source-side heat exchanger, a motor-operated valve, and a target-side heat exchanger are provided; and an outdoor fan which is provided for the heat-source-side heat exchanger. The target-side heat exchanger is capable of heating, by a refrigerant, fluid supplied from outside. The rotation number of the outdoor fan upon activation of the compressor when a difference between a temperature of the fluid supplied to the target-side heat exchanger and an outside temperature is equal to or larger than a predetermined temperature difference is smaller than the rotation number when the difference is smaller than the predetermined temperature difference.
