Do insulated radiator panels save money? - I'm testing them now

silvercar · 12 January 2007 at 11:21AM

My house has solid walls (1930s build). the walls are generally cold to touch except behind the radiators where they are warm (marshmallow melting wall).

Sounds like I would gain by fitting these panels. Some of the radiators, particularly the ones curved into the bays have very little gap between the wall and the radiator - how large a gap do I need to make these sheets worthwhile?

Some of the main rooms have radiator covers in MDF or wood. (stupid idea in my opinion, the wood warms up nicely!) They have to stay as the wooden flooring underneath them has not been completed. Could I put these insulation panels on the inside of the radiator covers? You can actually feel a hot draft coming out of the radiators with these covers on, so they do direct some heat. Unfortunately, its the radiators that are not on an outside wall that have the covers.

I have panels behind every radiator , been there several years, and D.I.Y so paid back by now. Wouldn't be without them...a bit off topic...this site is good for detail and a huge thread on multifoils..

Thats a good link Ken and a massive thread as well. Starting to work my way through it, if you've read it would you give a conclusion?

I didn't know about multifoils, interesting.

Not banned in the sense of being harmful, just not as effective as claimed.
Multifoil insulation is foil..bubble wrap...foil and as sold by the DIY sheds at £4 per sq metre. The foil seems be sprayed on.

the link talks about roof insulation. is it worth putting behind radiators on solid walls?

Well silvercar, thats what the whole debate was about ............. I think

I have solid walls and I think it is, I may do some temp tests when I have time........

like 2020 then.

Why don't you try one radiator and do temp tests above and behind the rad?
If something is wrong with this simple test, would someone please pipe up

Like I need to ask :rolleyes:

From a very quick read, because I'm building a woodshed, I thought multifoil was multiple layers of foil and thin insulation? I'll have to go back and have a better read when I have time.

Kitchen foil (£1.89 for 25 metres, just over a ft wide) pasted with heavy duty wallpaper paste onto cardboard (free) or bubble wrap from a garden centre has to be the cheapest way.
Must not touch the radiator, and either pasted or taped to the wall. Don't think my rads have the space to take profiled radiator panels.

It was suggested to me that those £1 car sunscreens, ones with foil reflectors, work well behind radiators. Double sided tape, cut foil to fit and away you go. Does seem to have saved me money in the last few months.

Good one Anne....double use.
