INSTANT HOT-WATER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an instant hot-water supply device capable of heating a heat exchanger even if water is not passed therethrough.

SOLUTION: In this device, a supply hot-water heating circuit 12 is thermally connected to a circulation water heating circuit. The supply hot-water circuit 12 is heated by a heating means 16 when water is not passed therethrough. The device comprises a pressure reducing means 31 formed to release hydraulic pressure to the circulation water heating circuit 13 when a pressure is increased to a specified pressure or higher. Even when a heat capacity is increased and the amount of hot water generated is increased by the supply hot-water circuit and the circulation water heating circuit thermally connected to each other, hot water of appropriate temperature can be rapidly supplied.
