Abstract

PURPOSE: To enable an instant feeding of hot water by operating a circulation pump of minimum capacity in a hot water feeding system using a main body of an instant water heater.
CONSTITUTION: A hot water feeding pipe 7 from a main body 1 of an instant water heater is provided with a return pipe 13. A circulation passage is constituted by the hot water feeding pipe 7 and the return pipe 13. A circulation pump 20 for circulating hot water in the hot water feeding pipe 7 of which temperature is less than a specified temperature while reheating it in a circulation passage, an electrical heater 21 and a thermostat 19 are disposed in the return pipe 13. With such an arrangement, the circulation pump 20 satisfying only a function of circulation normally required and having a small capacity can be selected, both initial cost and running cost can be reduced and at the same time noise or vibration can also be reduced.
