PURPOSE:To simplify the system and reduce the cost by constituting a reservoir tank with a sealed resilient tank, and charging the reservoir tank with the function of an accumulator by making use of the resiliency. CONSTITUTION:A pump 2 draws water from a water collecting tank 3 through a check valve 6, and pressurize and supplies the water to a reservoir tank 1 from a delivery pipe 7. Since the reservoir tank 1 is made of plastic etc. and has a resiliency, it absorbs the pressure change due to the starting and stopping of the pump 2. In this manner, the water can be supplied at a stabilized pressure, and changes in the hot water temperature and the delivery rate of hot water can be reduced. |
