PURPOSE:To feed a high-temperature hot water at a stable temperature, by a method wherein a combustion stopping time of a burner in a hot water warmer, connected to a water warmer utilizing solar heat, is regulated corresponding to temperature of hot water from the water warmer harneshing solar heat. CONSTITUTION:A hot water pipe 6 from a water warmer A harneshing solar heat is connected to a fin tube 2, of which a heat exchanger D in a water warmer E consists, and a water inlet port of a water pipe 3, and a hot water feed amount detecting switch 7 and a feed hot water temperature detecting switch 8 are located at the hot water feed pipe 6. Output signals from the switches are sent to an operational circuit C to operate a combustion time of a burner device B, which is necessary to the rise of temperature of hot water from a faucet up to a usable hot water temperature, and a fuel pump 12 is made to suspend operation. |
