<P>PROBLEM TO BE SOLVED: To provide bath equipment in which a hot water/water circulation passage is formed between a heat source machine generating hot water/water and a bathtub, or between the heat source machine and a heat consumption terminal, and a circulation pump disposed in the circulation passage, can be operated under a condition suitable for the installation environment of the bath equipment. <P>SOLUTION: A rotating speed variable-type pump is employed as the circulation pump, the rotating speed of the circulation pump is increased from a lower limit set value, a searching means is provided to search the rotating speed of the circulation pump to keep the flow rate of hot water/water flowing in the circulation passage to a prescribed value or more, as a lower limit flow rate rotating speed in the rotating speed increasing process, and further a setting means is provided to set the rotating speed of the circulation pump in a normal operation to be the lower limit flow rate rotating speed or more searched with the searching means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
