Oil filled radiators provide a most efficient and cost effective electrical heating solution for longer term use. They are ideal for larger areas such as living rooms or any area needing constant temperature and are set on castors for portability.
They operate by heating oil sealed within the unit, this heat transfers to the outer metal surfaces to heat the surrounding air. The heated air rises to be replaced by cooler air leading to a slow warm air circulation in what is known as a convection cycle. This gives an even, comfortable temperature around the room.
For oil filled radiators immediate heat does not feature but once temperature is reached the oil retains the heat and is powered down. An internal thermal control only calls for power after the oil temperature eventually drops. This provides an efficient, steady, silent operation, ideal for longer term use. Many models have a timer and ECO functions for increased user control.
Once switched off the radiator's retained heat releases slowly to give a gradual temperature reduction to the room.
