Abstract:
An auxiliary heating element acts on a steam trap connected to the return outlet of a radiator. A check valve placed between the trap and the radiator prevents dissipation of the steam generated by the auxiliary heating element into the radiator. A thermostat provides automatic control over the operation of the heating element and the radiator.
