Abstract: PURPOSE: To detect correctly a water pressure in a bath tub even in the case of circulation of hot water without stopping an operation of a pump by a method wherein a flange for fastening an inner wall of a bath tub is provided with a water pressure feeding inlet for communicating a clearance with an inside part of the bath tub and further the flange for fastening an inner wall of a bath tub is provided with a sensing- pipe connection port communicated with the clearance. CONSTITUTION: Hot water stored in a bath tub 6 flows from a water pressure feeding inlet 29 into a pressure sensor 23 in a sensing pipe 22 through a water pressure feeding passage 29a, a clearance 28 and a sensing pipe connection port 21. In this case, since the pressure sensor 23 detects a pressure caused by an amount of hot water stored in the bath tub acting at its set position, an amount of hot water stored in the bath tub 6 can be calculated by applying the pressure value. Even in the case that the hot water stored in the bath tub is being circulated, the water pressure feeding inlet port 29 for feeding the water pressure is placed at a position spaced apart from a flowing line of the hot water and also a place where a pressure variation caused by its flowing speed is hardly applied, it is possible to detect an accurate water pressure.  With such an arrangement as above, it is possible to perform an accurate detection of an amount of hot water stored in the bath tub 6.
