Title:
HOT-WATER SUPPLY APPARATUS COUPLED WITH SOLAR HEAT HOT WATER GENERATOR
Document Type and Number:
Japanese Patent JP3150238
Kind Code:
B2
Abstract:
PURPOSE: To obtain hot water of set temperature by connecting a hot-water outlet pipe of a solar heat hot water generator to a feed water pipe of an instantaneous hot-water heater to mix hot water of high temperature heated by the hot-water heater with hot water of low temperature from the hot water generator in a user to which hot water is supplied.
CONSTITUTION: A feed water pipe 21 and a hot-water supply pipe 22 are provided respectively at the inlet and outlet of a heat exchanger 11 of an instantaneous hot water heater 10, and a solar heat hot water generator 15 is provided in the pipe 21. Heating capacity of a gas burner 12 of the heater 10 can be varied by changing the degree of opening of a proportional gas valve 14. A hot water supply apparatus is controlled by an electronic controller 30. Sensors 32-34, 36 and solenoid valves 14, 35 are connected to the controller 30, and a remote control operation device 31 including a regulating knob 31a, for setting hot-water delivery set temperature and total hot-water delivery amount for a bathtub 25 and an indicator is connected to the controller 30. By this method, temperature of hot water, while the heater 10 is operating at low heating capacity, becomes higher than a set temperature; however, the hot water is mixed with hot water of low temperature, at the time when the heater 10 is not operating, in a user to which hot water is supplied, so that set temperature can be obtained.
