1. A water heating system comprising:
a refrigerant circuit that comprises a compressor and in which a refrigerant flows; and
a water circuit in which water flows, wherein
the refrigerant circuit shares with the water circuit a water heat exchanger that heats the water using the refrigerant discharged from the compressor,
the water heat exchanger comprises a heat-exchanging unit in which the refrigerant exchanges heat with the water at a water outlet portion, and
the refrigerant circuit further comprises a heat radiator that is disposed between the compressor and the heat-exchanging unit and that radiates heat of the refrigerant discharged from the compressor, to water that flows on an upstream side of the water outlet portion.
