Title:
HOT WATER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2022166676
Kind Code:
A
Abstract:
To provide a hot water supply system capable of reducing a change of a hot water delivery temperature when a tank hot water delivery mode is switched to an auxiliary water heater hot water delivery mode to switch a temperature sensor for detecting the hot water delivery temperature.SOLUTION: A hot water supply system includes hot water supply control means 16 that executes a tank hot water delivery mode of controlling a hot water delivery temperature by using a hot water supply outlet temperature sensor 29 when hot water is delivered from a hot water storage tank 10 and an auxiliary water heater hot water delivery mode of controlling the hot water delivery temperature by using an auxiliary water heater temperature sensor 40 by switching to hot water delivery from an auxiliary water heater 3 when the hot water storage tank 10 runs short of hot water. When executing hot water delivery by switching the tank hot water delivery mode to the auxiliary water heater hot water delivery mode, the hot water supply control means 16 calculates a correction value between the temperature sensors from a difference of the detection temperatures between the auxiliary water heater temperature sensor 40 and the hot water supply outlet temperature sensor 29, determines either one of the auxiliary water heater temperature sensor 40 or the hot water supply outlet temperature sensor 29 as a correction target temperature sensor, and corrects the detection temperature obtained by the correction target temperature sensor on the basis of the correction value between the temperature sensors.SELECTED DRAWING: Figure 1
