PROBLEM TO BE SOLVED: To cope with both heat-storing systems of the latent heat-storing system and a sensible heat-storing system with a single form by controlling next conduction start time by the difference between the target temperature of a heat-storing body at the usage end time of a specific chamber and that of the heat-storing body at this time. SOLUTION: When late-night power is turned on, shift time dT of conduction start time starts to be counted by a throw control part, and a heater conduction control element is turned on when time T passes for starting conduction. When time To passes after the late-night power is turned off, temperature (t) of the heat-storing body in a specific chamber is measured and is compared with a target temperature t0 of the heat-storing body at the usage end time t0. In this case, by regarding that the amount of heat being accumulated by the heat- storing body has exceeded a required amount of heat for heating, next conduction start time T1 is delayed from the conduction start time T at this time by dT for starting conduction. Also, at t=t0, the amount of beat being accumulated in the heat-storing body is judged to be appropriate for the required amount of heat for heating. |
