Can I use the ordinary aluminium foil I use in the kitchen?
Kitchen foil placed behind the radiator can save a small amount of energy by reflecting infra-red heat. However it is very difficult to fit, it has a limited life and can be unsightly as it curls at the edges and easily becomes detached from the wall. Unlike HEATKEEPER Energy Saving Radiator Panels, kitchen foil has no insulating benefit and it does not improve the heat distribution in the room.
