Whats more expensive the Bacofoil or he reflective tiles lol!
Just get some old polystrene from old packaging and cheap foil from somwhere like Home bargains cut to size glue and stick, jobs a good'n:thumbsup:

Surely this deal should be HOT HOT HOT........

No ?????.........- i'll get me coat..........
#5
These Tiles are quality and blend in behind the radiators nicely.

I've already noticed that the tiles remain cold when the heating is on where as before the wall would soak uo the heat. Now the hot heat is returned back in to the room.

B&Q seem to be selling all energy saving product cheaply at the moment
#6
thanks OP was looking for some of these...
#7
How is possible to fix these to a wall if the radiator is on the wall?
#8
how easy are these to install? stick them on? or cement? do you need to take off the radiator generally ?
#9
Just curious as to how you attach them to the wall ?
#10

I would also like to know the answer to this question... I thought it would essentially just be giant stickyback sheets of foil?!
#11
From what I've just read I think the idea is that you cut it to size, and cut vertical slots so it sits on the wall mounting brackets.
banned#12
I did mine with double sided tape. Stick the tape on the back, pull off the covering layer of the tape, gently push it behind the radiator (between the supports), then stick a long ruler behind the radiator to stick it to the wall all the way down.
#13
Isn't the one from screwfix better value for money? Since you get 2.5m squared, whereas the b&q version only gives you 1m squared. So you get an extra 1.5m squared for only just over £1 more?! Although the screfix one requires you to paste it to wall, but would allow you to cut to size better, since on a roll?!
#14
Screwfix sell this on a roll, which all though may be cheaper (TBC) is a damn sight more difficult to fix to a wall without removing the rad.

Fixing advice;

These 'tiles' will be easier to use than the roll if only because they don't want to keep curling up! You could try using D/S tape along the top edge to fix the tile - normally the heat might dry out the stickyness of the tape, but as it is behind the reflective surface you might just get away with it! Get someone with small hands to do this job as they'll have more room to manouvre down the back of the rad. If the tape fails use a glue gun. Don't worry about fixing the tile on all it's edges as it's behind a rad and is not likely to knocked off.

Naturally the best time to put this stuff on is when the rads are off the wall. Good luck...
#15
is this not better value?
#16
Isn't this pointless if all your radiators are on interior walls like mine, ie any heat loss will be to another part of your house.

don't you have a radiator anywhere in your house under a window?
#18
I thought radiators were mainly located below windows. Most of mine are, and are therefore on an exterior wall.:?

That's what I was thinking. Even on exterior walls I can't believe 30% goes through to the outside - the bricks would act like storage heaters.

Even so, the idea is that this throws the heat back into the room so you feel it when you are in the room, rather than heating up an interior wall which lets heat out once the room temperature has dropped again (eg. at night, when out at work, etc).

I use the car windscreen sun reflectors (shiny foil type) from the 99p shop or look out for thicker/better ones sometimes given free with coca cola purchases...............

2.5m squared is 6.25 square meters, so more than 6 times the amount for your extra pound!

Is this on special offer or just normal price?

Compete waste of money.The great proportion of heat produced by domestic radiator is from convection, not radiation.

I suppose if you want to waste money, this is a cheap option; but I would suggest that not wasting money on scientifically dubious 'solutions' to problems that don't exist is probably a better idea :roll:

Feel free to continue on in ignorance if that's your preferred option. The more people keep wasting money on stuff that doesn't work, the better it will be for the economy.

"30% of radiator heat lost through walls"
That is a ridiculous figure. As has been pointed out, most of the heat from a radiator comes out of the top by convection. If you don't believe me, block the top of a double radiator (easier to do than a single) and see how effective it is.

Bit tetchy Jeezeypeeps, how do you know from my comment whether or not I agree with you?
Anyway, convection - hot air.................

As a scientist, maybe you can enlighten us as to the actual proportion of heat given off as radiation/convection. Personally I've always found convection heaters to be pretty useless since the hot air just floats up to the ceiling, so maybe the radiated heat is the more important element.

In any case, if you reflect the heat from the wall back into the radiator it's going to take less energy to produce your convection, so your argument is irrelevant. I agree you’re right to be skeptical about the claims made for these reflectors but with fuel prices on the up they might be worth considering.

I doubt those figures actually mean that 30% of the heat is lost through the walls directly behind the radiators , i think they maybe referring to heat lost through all the walls in the room which is a little more believable. However cavity wall insulation should help to reduce this considerably and i would have thought the amount of heat lost through the wall directly behind the radiator providing the wall is insulated would be negligable.
However every little helps i guess but i wont be buying these as i have invested in low energy bulbs throughout the house , changed my laundry loads to 30 degree washes (except for white loads which remain at 60) and have an 'a' rated tumble dryer which uses a heat pump and costs half the amount of running a standard 'c' rated equivalent , all of which should help in reducing those bills , oh and saving the planet too ;)

Yes, that sounds right - but in that case they are making a misleading claim because it has very little to do with radiator foil.

Yep.

Radiators generally do not radiate. They are white which you should all know is a very poor radiator (compare black stone to white stone on beach on sunny day).

Heat rises and therefore radiators create convection currents.

It is not radiation that is losing heat out of walls. They will conduct a very small amount out but there's not alot you can do about that other than cavity wall insulation.

100% of heat energy is lost from a heated room, probably 70% through the ceiling and 30% through the walls, that energy has to go somewhere. If you heated a room up and left it with the door closed for a week the heat would have escaped wouldn't it? The room wouldn't still be hot.
#37
I'm with the skeptics here. Radiators are actually 'convectors'.

see http://www.diyfixit.co.uk/diy/centralheating/radiators/radiators.html

As such they require that gap behind them and blocking that (even a bit) probably does more harm that good.
#38
bigcheese1

White radiators hardly radiate at all.

Does anyone think using tin foil (or similar substance) will actually slow down the temperature loss through it?

Think of it this way, heat one side of a bit of tin foil with a blowtorch, how long until the heat reaches the other side? Almost instantly, it's a good conductor, so it's not doing anything to slow down the heat loss through it.

Now take a brick and heat one side with a blow torch, how long until the other side gets hot? A long time, because it's a poor conductor, it's slowing down the heat lost through it. (credit to whoever posted this example a few months ago)

Hillarious, even though these have been argued as completely pointless through scientific reason - they are still voted HOT!!!

White paint has a high emissivity: it is reflective in the visible but not in the IR

It doesn't make much difference what colour you paint your radiator unless you paint it with metalic paint. About 1/3 of the heat is radiated.
