Steam enters the radiator through a control valve, while a steam trap facilitates the exit of air and water towards the boiler, ensuring steam remains trapped inside. As steam fills the radiator, air escapes through the open trap. Once fully saturated, the trap’s thermostat expands, sealing the outlet and preserving steam inside. Upon condensation, the trap reopens to allow water to return to the boiler. Air is vented through master vents near the boiler, and condensate flows back to repeat the cycle.
Control valves may be manual or thermostatic, with the latter providing enhanced comfort and control, contributing to energy efficiency and reduced fuel bills. Thermostatically-controlled radiators require a vacuum breaker, which we supply as standard.
