    Radiator Reflector Foil

    Greetings. I just received some energy saving tips from my supplier. The guy said I should get some Radiator Reflector Foil, to stop heat escaping behind the Radiator. This is the first time I'm hearing about this. Does anyone know if it really works? Thanks.

    can do it with tin foil

    it has been around for years,it reflects the heat back into the room so keeping heat circulating,well worth investing in a roll that will do 3 or 4 rads

    Tin Foil should do the job, however if you get in touch with your local council they might be able to help (energy saving costs etc)

    I can't get my head around how a piece of foil can reflect heat - light yes but heat?
    Foil is thin metal so will conduct heat not actually reflect it

    That said if it was me (I have storage heaters which are pre insulated) I'd look at using a thin fire resistant foam/insulation in between the wall and foil because without insulation the radiator heats up the wall as well as the room and whilst it's nice to have warm walls most of the heat is wasted.

    But that's me - others might have other answers

    We had it behind radiators when I was a kid . It was foam backed and it didn't stick . Just kept falling off . Assume they may have corrected that design fault by now . It works best for older houses with poorer insulation.

    Thank you all for your replies. Gonna invest in a roll.

    Remember in school when they told you about radiation and all that. Heat and light are both types of radiation, just different frequencies/wavelengths. Heat (eg. infra-red) is outside our visible spectrum

    Re the OP. The foam backed stuff is better, as alu-foil on it's own will conduct some of the heat to the wall. The foam will insulate against this happening. Worth checking Aldi/Lidl as it was a bit cheaper than B&Q etc. Still, not that expensive though.

    I saw some on Amazon for £5.

    Some heat is in the form of electromagnetic radiation (light) and would be reflected. However, Wikipedia seems to agree that it is negligible compared to convective heat which you think would be transmitted through the foil (unless it has some insulating coating).

    Tin foil is the absolute worst thing you could use as it will conduct the heat into the wall

    The proper stuff has a layer which doesn't absorb heat

    I used a windscreen protector from tesco for £2. it seemed to work as it had a silver reflector on both sides. the room felt warmer

    Depends which way round you put it
    fairly sure it is shiny side away from where you need the heat

    Does nothing at all! Not worth a penny....

    I use radflek on all my radiators, except bathrooms. It works. Feeling behind the foil when the radiators have been on they are still stone cold. I can thoroughly recommend although they aren't cheap.

    I was advised the same recently. we redecorated the house, got some resistors in ast year and chucked most of them out, d'oh! oO

    We have radiator boxes in both living and dining rooms.
    I bought a roll of the radiator backing stuff you mention (its plastic, similar the the windscreen things mentioned above, but thinner).
    I put a piece down the back (with 2 slots in for the radiator brackets), and lined the bulk of the solid parts of the radiator box, also made a scoop so the airflow through the rad would be guided out of the top vents of the box.
    Seemed to make a considerable difference as the box no longer got warm and you could feel the heat coming out as you walked past it.

    I found changing to a column radiator in the hall made the biggest difference, but they're expensive.
