<p>PURPOSE:To permit an user to select the instantaneous maximum usable capacity of the hot-water supplier properly by a constitution wherein a heating device is made separable from a hot-water reserving tank and the heating device can be combined with the other hot-water reserving tank. CONSTITUTION:The hot-water reserving tank 1 is covered by a heat insulating material to restrict heat emission therefrom and equipped with openings, such as a water feeding port 1a, a hot-water supplying port 1b and a return pipe connecting port 1c, an upper hot-water temperature sensor 2a, a lower hot-water temperature sensor 2b and an anti-corrosive electrode 3. Such hot-water reserving tank 1 is formed integrally to constitute the hot-water reserving tank section A. The heating device B is constituted by accommodating a combustor 5, a heat exchanger 6, a control unit 8 and the like integrally and is arranged below said hot-water reserving tank section A detachably. Pipes 11, 12 function as the circulating pipes of reserved hot water and are constituted so as to be detachable by a plumber or the like. For this purpose, the hot-water reserving tank may be exchanged easily and the proper hot-water supplier, in accordance with the instantaneous maximum usable capacity desired by the user, may be selected by changing only the hot-water reserving tank section without exchanging the heating device section.</p> |
