HOT WATER EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide hot water equipment for re-heating and heat-keeping bath water by efficiently utilizing hot water storage heat in hot water storage type hot water equipment.

SOLUTION: The hot water equipment comprises a hot water storage tank 7; a heater 8 for heating water from the upper portion of the hot water storage tank 7; a first communication path 9 for allowing the lower section of the hot water tank 7 to communicate with the upper section; a boil-up pump 10 for supplying water to the first communication path 9; a second communication path 14 for allowing the upper side of the hot water storage tank 7 to communicate with the lower section; a re-heating pump 15 for supplying hot water at the upper portion of the hot water storage tank 7 to the second communication path 14; a water heat exchanger 16 for exchanging heat with hot water flowing through the second communication path 14; a heating control means 12 for controlling the boil-up pump 10 and the heater 8; and bath water circulation circuits 23, 24 for circulating bath water by a bath water circulating pump 18 for exchanging heat with the water heat exchanger 16.
