摘要： PROBLEM TO BE SOLVED: To provide a bath system in which the environment of using a bathroom, e.g. bathing environment, can be made comfortable. SOLUTION: The reheating/circulating circuit 26 of a forced circulation reheating bath heater can be switched between a direct heating circuit 7 circulating through a bathtub 4 and an indirect heating circuit 8 circulating through a heat discharging means 5 by means of a switching control unit 6. At the time of reheat operation, bathing/nonbathing is determined from abrupt variation of water level detected by a bathtub water level sensor 32. In case of nonbathing, three-way changeover valves 61, 62 are switched such that supply pipelines 26a, 7a are interconnected and return pipelines 26b, 7b are interconnected to raise the temperature of hot water in the bathtub directly. In case of bathing, the three-way changeover valves are switched such that supply pipelines 26a, 8a are interconnected and return pipelines 26b, 8b are interconnected to return hot water in an expansion tank 83 to a heat exchanger 27 and to supply reheated hot water to the heat discharging means. The heat discharging means discharges heat of hot water thus supplied to heat the bottom wall 42 of the bathtub thus raising the temperature of hot water in the bathtub indirectly.

摘要： PROBLEM TO BE SOLVED: To enable a heat of a bathtub water left to be natural heat sink after bathing is finished to be recovered and recycled. SOLUTION: A heat recovery system comprises a bath circulating circuit 19 for coupling the bathtub 12 to a bath heat exchanger 15 for heating the bathtub water, a heat exchanger 20 installed in a hot water storage tank 3 and connected to the circuit 19, a bypass route 21 provided to bypass the exchanger 20, and a first and second channel switching valves 22 and 23 for switching a circulation of the bathtub water through either the exchanger 20 or the route 21. Thus, when a temperature of the bathtub water is higher than a temperature of the hot water in the tank 3, the bathtub water is circulated through the exchanger 20 in the tank 3 to recover the heat of the bathtub water to the tank 3.

摘要： PROBLEM TO BE SOLVED: To obtain a shower device having a comfortable bathroom heating or hot water sprinkling means and to simplify a facility by branching a part of a warm water supplied to a bathroom warm air heater by a warm water supply branch means, and supplying it to the shower device having the sprinkling means. SOLUTION: A bathroom warm air heater 1 is installed on an upper wall in a bathroom 9, and a warm water supply forward circulating passage 12a and a warm water supply return circulating passage 12b are guided from a heat source equipment 11 disposed outside of the bathroom 9 into the bathroom 9. A three-way valve 3 for branching to supply the warm water to a shower device 2 having at least a hot water sprinkling means is disposed in the heater 1. The valve 3 is switched, and the heater 1 sprays the hot water obtained by heat exchanging the warm water supplied from the equipment 11 with a heat exchanger 5 into the bathroom 9, thereby air conditioning to heat in the bathroom 9. Then, the warm water supplied by branching to the device 2 is dropped and hence hot water sprinkling can be conducted.
