PURPOSE: To obtain a heating controller for an electric warm water oven which can delicately control a variation in a heating temperature to a bathing temperature in response to a variation in a using hot water quantity and save an electricity.
CONSTITUTION: Fuzzy control means 59 infers variation in an energizing time necessary to heat water to a bathing temperature on that day according to delicately empirical fuzzy rule for various conditions from a residual hot water quantity of past predetermined period by residual hot water quantity converting means 4. Calculating means 60 calculates an energizing time, a heating temperature and an energization starting time necessary to heat it to a bathing temperature from the maximum energizing time of a past predetermined period and the variation in the energizing time by the means 59. Heat generator control means 11 controls an energizing amount to a heat generator 2 by energizing means, and automatically controls heating of hot water in a hot water storage tank 1 to a bathing temperature. Thus, a delicately heating to the bathing temperature responsive to the variation in the using hot water quantity can be performed, and an optimum hot water quantity can be obtained.
