A flow rate detector 10 which incorporates a float 14 provided with a permanent magnet 13 at an upper part and is provided with a lead switch 12 on the outside of a main body 11 thereof is provided in the pipe 5, and combustion is controlled by a combustion- controlling circuit 15 for a burner 3. At the time of starting, water is fed from the interior of the bathtub 4 in the direction of an arrow A by the hand, combustion is started by causing the circuit 15 to self-maintain, and is continued.
