<p>PURPOSE:To reduce heat loss by a method wherein a proper heating temperature is obtained from feed water temperature so as to impress only the proper amount of heat to a heating source. CONSTITUTION:The temperature of water fed into a hot-water reserving tank is detected by a feed water temperature detecting means 10 while the necessary heating temperature is operated by an operating means 11 from the feed water temperature detected by the means 10. Hot-water temperature in the hot- water reserving tank is detected by a hot-water temperature sensor 12, and when the detected hot-water temperature has arrived at the neceasary boiling temperature, operated by the operator 11, heating effected by a heating source 14 is stopped by a control unit 13. Only the proper amount of heat is impressed to the heating source, therefore, the hot-water, at the temperature higher than the required temperature thereof, will never be left for a long period of time and the heat loss, due to the natural heat dissipation from the hot-water supplying machine itself, the heat dissipation of the high temperature water stayed in pipelines and the like, may be reduced.</p> |
