Does putting reflective foil behind radiators work?

Silver foil placed down the back of a radiator will reflect heat back into a room rather than letting it uselessly escape through the walls of a house. However, the Energy Saving Trust says that foil behind radiators is not worth doing if you already have cavity wall insulation.

How much difference do radiator reflectors make?

Radflek Radiator Reflectors can reflect almost 95% of the heat from the radiator’s back into your home, thus cutting down the heat loss that usually takes place through the walls. Imagine losing 45% of the heat produced by the radiator! That accounts for an additional several hundred bucks in the electricity bill.

Do radiator covers stop heat coming out?

Do radiator covers block heat? No, a cover does not block the heat from your radiator. A radiator heats a room through by warm air rising from the radiator to the ceiling, which is then moved around the room and heating it.

Can you use aluminum foil to reflect heat?

Something that is silver such as aluminum foil has a rather low emissivity. Not only is this a good reflector to your eye of visible light, it is a good reflector of heat. Tin foil reflects heat, maybe even better than it reflects light. Being a very good reflector of heat, it has a low emissivity.

Are radiator heat reflectors worth it?

Caitlin Bent from Energy Saving Trust, says: Reflective radiator panels can help to keep your home warmer by reflecting heat back into the room, which would otherwise be lost through the walls. This is because they prevent heat escaping to the outside – so more heat is kept within your home.

Does aluminum foil reflect heat?

Tin foil reflects heat, maybe even better than it reflects light. Being a very good reflector of heat, it has a low emissivity. The object is something heat cannot pass through being either absorbed or reflected in this case.

Can you put things on radiator covers?

Because most covers have elevated tops, the covers’ tops are significantly cooler, and this allows select items to be placed there. Even heat-sensitive items like plants can be placed on a well-insulated radiator cover.

What side of aluminum foil reflects heat?

The shiny side reflects more heat than the dull side. So think about why are you using the foil? If to protect your food from heat — shiny side out. If to keep the heat in — then shiny side in.
