Abstract
An electric storage heater assembly which includes a core and a resistance heater for the core. A charging switch is in series with the resistance heater and an electric comparator for operating the switch has two inputs connected to first and second controls which are responsive to the instantaneous temperature of the core and the final temperature of the core for the preceding charging period. The first comparator input is also connected to auxiliary controls which sense indoor and outdoor temperatures and provide signals which are summed with the signal which represents the core temperature.
