<p>PURPOSE:To improve the hot water supplying quickness, energy conservation due to variable hot water quantity, economies, reliability, degree of freedoms of installation, workability of the apparatus. CONSTITUTION:The hot water storage type electric warm water machine comprises a hot water storage tank 1, a circulating pump 2, a heating unit 3 having a heater 4, a heat source unit 6 having a hot water relieve valve 5, a forward tube 7 for connecting a lower part of the tank 1 to the pump 2, a return tube 8 for connecting the unit 3 to an upper part of the tank 1, wherein the relieve valve is provided at an inlet side of the pump. Heated high temperature water is stored from above the tank to provide hot water promptness and hot water amount variation. the tank and the unit are separated to improve degree of freedoms of installation, workability, and maintainability, and further a hot water relieve valve is provided at a low temperature side to improve economy and reliability of an apparatus. The valve 5 is operated by pressure thereby to improve comfortableness at the time of using hot water and reliability of the apparatus.</p> |
