<p>PURPOSE:To perform optimum automatic heating-up control during the year by a method wherein the heating capacity is quantitatively controlled by correcting the heat quantity necessary for user in a unit period based upon the heat quantity in residual hot water in the previous unit period. CONSTITUTION:The titled control device is provided with a first calculating means (c), which calculates the required heating temperature based upon the water temperature detected by a water temperature detecting means (a) and the heat quantity necessary for user, a second calculating means (h), which calculates the daily heat quantity in residual hot water based upon the energizing hours measured by an energizing hour measuring means (g) and the required heating-up temperature calculated by the first calculating means (c) and a memorizing means to record the daily heat quantities in residual hot water calculated by the second calculating means (h) as a lot over a unit period. Heat quantity necessary for user in a unit period is corrected based upon the daily heat quantities of residual hot water, which are memorized in the memory means (i) as a lot over the previous unit period. For example, because, in the first unit period T1, the heat quantity of residual hot water for the fourth day is the minimum value Qmin1 and larger than the optimum marginal heat quantity of residual hot water Qg, the value of the expected heat quantity Qu1 necessary for the unit period T1 substracted by (Qmin1-Qg) is employed as the heat quantity Qu2 necessary for the following unit period T2.</p> |
