PURPOSE:To provide a bath system equipped with hot water heating capable of injecting circulation water into each water passage in a short time upon preparation operation. CONSTITUTION:A cistern 1, a circulation pump 2, and a heat exchanger 3 are parallely disposed, and first and second circulation water passages 4, 5 are connected between the heat exchanger 3 and the stream 1. Upon injecting the circulation water into the first and second circulation water passages 4, 5, control means 6 electrifies the circulation pump 2 to fill the second circulation water passage 5 with the circulation water, and thereafter it electrifies a solenoid opening/closing valve 41 to also fill the second circulation water passage 5 with the circulation water. |
