How Does An Oil Filled Radiator Work?
Each unit contains a special heat-efficient oil inside, which is then warmed with electricity when plugged in and switched on. The heated oil circulates through the radiator coils and fins to generate warmth through the process of convection, which allows the transfer of heat through a liquid. Cold air that is heated by the warm fins then rises, drawing in the air below it, and this process repeats itself. Sealed within the radiator, the oil becomes warm but never burns, and therefore never needs replacing or refilling, allowing for efficient operation. Lacking fans to circulate the air, oil filled radiators are practically silent. Their heat-retaining abilities allow them to continue warming an area for some time even after they are switched off. Because of the oil’s high boiling point, it safely remains in liquid form even when the radiator is on full power, and this means the unit does not have to withstand high pressures. Since the oil will retain its heat for some time, these radi
