PURPOSE:To make a bubble bath possible and obtain a hot-heat effect to quicken the circulation of the blood by feeding hot water into a bathtub equipped with bubble generating means by a hot water feed device having a heat exchanger for hot water feed and a circulating pump disposed on the way of a pipeline through which a filter provided in parallel with a branch pipe communicates to and is connected with a heat exchanger for additional heating. CONSTITUTION:Hot water is fed into a bathtub B equipped with bubble generating means 25 by a hot water feed device 1 having a heat exchanger 2 for hot water feed, a hot water storage tank 31 wherein hot water heated by the heat exchanger 2 for hot water feed is stored, and a circulating pump 4 being a forced circulation means disposed on the way of a pipeline through which a filter 5 provided in parallel with a branch pipe 22 communicates to and is connected with a heat exchanger 6 for additional heating. Since such a constitution allows to effect heat-exchanging by operating the heat exchanger 2 for hot water feed and the heat exchanger 6 for additional heating when hot water is fed into the bathtub B, a heat-exchanging efficiency is not reduced even in the case of an increase in the quantity of hot water. Furthermore, since the branch pipe 22 being a hot water passage is additionally provided between the filter 5 and the heat exchanger 6 for additional heating, this makes it possible to feed and circulate a large amount of hot water, and simultaneously, since the circulating pump 4 is usable for a bubble generating means, the sufficient jet stream of hot water can be obtained to provide a bubble bath. |
