<p>PURPOSE: To specify a range of increasing in temperature to enable hot water of high temperature to be fed by a method wherein in the case that hot water heated to a high temperature at a heat exchanger is supplied to a bath tub and a temperature range for increasing a temperature of hot water stored in the bath tub is set, an equation for calculating an amount of hot water to be added is specified. CONSTITUTION: In a hot water feeder having a function for adding hot water of high temperature, a standard value of a temperature rangeΔT is stored in a ROM of a controller 18. Then, when a user performs a plurality of times of depressions of a switch 14 of a remote controller 19 for use in adding hot water of high temperature, the temperature rangeΣT becomes high in response to the time of depressions. When a starting command is issued, an amount of hot water Q and a hot water temperature T in a bath tub 41 are confirmed, a water solenoid valve 13 is opened, hot water heated up to a high temperature by a heat exchanger 3 flows into a bath tub hot water feeding pipe 5 and reaches the bath tub 41. In this case, an amount of hot waterΔQ to be added is calculated by an equation ofΔQ=(Q.ΔT)/(TH-T-ΔT), whereΔT is an initial set temperature range, Q, T are an amount of hot water and a temperature of hot water in the bath tub when confirmed, and TH is a temperature of supplying hot water of high temperature to be added.</p> |
