PURPOSE:To re-burn bath water after the feed of hot water to a bath tub and to shorten a bath water heating time, by a method wherein, in an automatic bath hot water feeding heating apparatus, during motion of the feed of hot water to a bath tub, circulating water in a hot water circulating flow passage is heated and controlled to a set temperature. CONSTITUTION:A two-can three-water type automatic bath hot water feeding heating apparatus is provided with a hot water feeder 13, feeding hot water in a bath tub 21, a heater 14 having a hot water circulating flow passage 12 circulating hot water through a radiator 28 for heating, and a heating coil 35 for heating bath water 37 in the bath tub 21 by means of hot water in a flow passage 1. Further, a control circuit 41 is provided for controlling a hot water feeder 13 to automatically fed hot water in the bath tub 21, and actuating the heater 14 to heat and control circulating water to a set temperature. Thus, when through control of the feed of hot water to the bath tube 21 the control circuit 41 detects it to actuate the hot water feeder 13, hot water having a given temperature is fed in a given amount to the bath tub 21 from the hot water feeder 13. Simultaneously, in linkage with the motion of the hot water feed, the heater 14 is actuated, and circulating water for heating is heated and controlled to a set temperature. |
