<p>PURPOSE:To enable hot water having a predetermined temperature and a desired amount of hot water to be accumulated in a hot water accumulation tank by a method wherein an interior of the hot water accumulation tank is divided into a plurality of areas, a remaining amount of hot water within each of the areas and its temperature can be detected and at the same time a desired amount of hot water and a hot water temperature are selectively reserved and compared with the detected amount of remaining hot water and its hot water temperature to operate to feed hot water in correspondence with the amount of lack of hot water and its hot water temperature. CONSTITUTION:Signals indicating a hot water amount and a hot water volume which are reserved and selected by a reservation switch 35 are inputted to a calculation part 31, compared with a remained amount of hot water and its temperature within a hot water accumulation tank 5 which are detected by a hot water temperature sensor 28. In case that there are a lack of amount of hot water and a hot water temperature, a signal corresponding to a lack of hot water is outputted to a hot water feeding control part 30, a hot water feeding operation instruction signal is outputted from the control part 30 to an indoor control part 41 and an outdoor control part 42 through an air conditioning/hot water feeding comparator 40 and at the same time a circulation pump is started to operate and a hot water feeding operation is started. When the amount of hot water in the hot water accumulation tank 5 and its temperature are reached to the predetermined amount of hot water and hot water temperature, they are displayed at a remaining amount of hot water displaying part 33 and at the same time a stop instruction is outputted from the calculation part 31 and the hot water feeding operation is stopped.</p> |
