PURPOSE:To increase the number of circulating uses of hot-water in a bathtub and permit the improvement of water saving rate as well as the saving of the heat energy by a method wherein the water in the bathtub is sterilized and filtered while high- temperature refrigerant gas from a heat pump is circulated for heating the hot-water in a hot-water supplying tank and the same in the bathtub. CONSTITUTION:When a pump 22 is driven, hot-water in a bathtub 1 is introduced into a filter 21 to remove foreign matters and is injected into the bathtub 1 through a water sending pipe 23. An activating tank 25 effects the exchange of ion of the hot-water of the bathtub, which has passed through the filter tank 21, to return the quality of the hot-water to be original quality of water, while effective constituents included in actuating stones, are eluded into the hot-water in the bathtub to increase bathing effect. Further, an ozone generator 51 is provided in a sterilizing means 5 and ozone from the ozone generator 51 is injected into the bathtub 1 through the water sending pipe 23 together with jet stream. A heating coil 8 is provided in the activating tank 25 in a circulating tank 2 to heat the hot-water of the bathtub. Refriger ant gas is supplied to the heating coil 8 from a heat pump 3 to heat the hot-water of the bathtub through heat exchange. |
