description PROBLEM TO BE SOLVED: To provide a hot water supply control method of a hot water circulation type heater capable of satisfying both contrary demands of high output and high efficiency while satisfying request on priority at that time. SOLUTION: This hot water supply control method achieves high output (S1, S2) by increasing a temperature of water of low temperature by opening a bath heat valve and allowing the water of high temperature to pass through a bath heater circulation passage, when hot dash is required. The bath heat valve is closed to switch the priority from high output to high efficiency (S3, S4), after keeping the high output for a set time T. When a detected temperature of the water of low temperature is lowered to 65°C, the bath heat valve is opened again to achieve high output (S5, S6). The bath heat valve is closed again when the number of low-temperature terminals having hot dash demand is reduced, or the set time has passed, to switch the priority to high efficiency (S7, S8, S9).
