A water heating system includes: a refrigerant circuit that includes a compressor and in which a refrigerant flows; and a water circuit in which water flows. 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 includes a first heat-exchanging unit in which the refrigerant exchanges heat with the water at a water outlet portion. The refrigerant circuit further includes a heat radiator that is disposed between the compressor and the first heat-exchanging unit and that radiates heat of the refrigerant discharged from the compressor. The heat radiator is configured to radiate heat of the refrigerant to water that flows on an upstream side of the water outlet portion.

Water heating system

A controller performs a first operation in which a heat source device directly or indirectly heats water in a first channel of a heat exchanger and a second operation in which the heat source device directly or indirectly cools the water in the first channel of the heat exchanger after the first operation ends.
