Hot water storage type heat pump unit

摘要

A hot water storage type heat source device is composed of a heating section 11 for heating water with electric power from a peak cut power source 10 whose power supply may be stopped on account of a power supply side, a boiling control section 12 for receiving electric power supplied from a commercial power source 30 other than the peak cut power source 10 and controlling the heating section 11, and a hot water storage section 2 for storing hot water heated by the heating section 11. Even when electric power supply from the peak cut power source 10 is stopped and thereby the heating section 11 is stopped, the boiling control section 12 operates with electric power from the commercial power source 30.
