Electrical storage heater

摘要

An electrical storage heater has a housing with storage bricks, a switch box and in the base below the bricks, a cold air inlet with warm air outlet. In the switch box is a controller (6) to switch the heating element (3) on and off, in series with a safety temperature limiter and the contacts of a temperature relay. There is a discharge controller(4) which switches a fan(18) off or on, according to the room temperature. In the circuit of the heater controller and that of the discharge controller are further temperature limiters in series, both being located in the cold inlet or warm air outlet.
