<p>PURPOSE: To enable the continuation of a followup boiling operation of a bath and a heating operation even when a water heating temperature sensor breaks down and moreover, preventing of at least a user from suffering scald or the like in the water heating operation. CONSTITUTION: This storage type hot water supply system has a hot water storage boiler body 10 which is provided with a burner 12 for heating and a hot water storage tank 14 while heat exchange coils 15 and 16 for heating and follow-up boiling of a bath are arranged in the hot water storage tank 14, a water feed pipe 20, a hot water delivery pipe 40, a bypass pipe 30 for mixing water directly connected to the hot water delivery pipe 40 branched off in the course of the water feed pipe 20, a mixing adjustor 50 which is located at a converging point between the bypass pipe 30 and the hot water delivery pipe 40 and adjusts the mixing ratio to produce hot water at a set water heating temperature, a hot water supply pipe 60 and a water heating temperature sensor 61. A controller 70 is provided to give a command to open the path fully on the side of the bypass pipe 30 of the mixing adjustor 50 as safety operation in stead of stopping the operation of the burner 12 of the hot water storage boiler body 10 as safety operation when the water heating temperature sensor 61 breaks down.</p> |
