<P>PROBLEM TO BE SOLVED: To provide a technique capable of stabilizing a temperature of hot water to be supplied to a hot water supply place when switching a heat accumulation hot water supply operation to a combustion hot water supply operation. <P>SOLUTION: A hot water storage type hot water supply system includes a hot water storage tank, an auxiliary heat source machine for heating water from the hot water storage tank when necessary, a heat source machine route for sending water from the hot water storage tank to a hot water supply place through the auxiliary heat source machine, a bypass route for sending water from the hot water storage tank to the hot water supply place without being passed through the auxiliary heat source machine, a bypass control valve arranged on the bypass route, and a flow rate acquisition means for acquiring a total flow rate of water allowed to flow through the heat source machine route and water allowed to flow through the bypass route. The hot water storage type hot water supply system can switch the heat accumulation hot water supply operation to the combustion hot water supply operation and vice versa. In the heat accumulation hot water supply operation of the hot water storage type hot water supply system, an opening degree of the bypass control valve is decreased in accordance with a decrease of the total flow rate acquired by the flow rate acquisition means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
