Abstract (en)

[origin: EP2778555A1] A control device of the present invention controls an opening degree of a three-way valve so that a temperature of water on an upstream side of a heating portion increases by a predetermined temperature until the temperature of the water on the upstream side of the heating portion reaches a target temperature after a heat pump operates. Alternatively, the control device controls an opening degree of a vane so that a temperature of water on a downstream side of the heating portion increases by a predetermined temperature until the temperature of the water on the downstream side of the heating portion reaches a target temperature after a heat pump operates.
