Radflek radiator reflector is a specially treated aluminium foil that is positioned between the back of the radiator and the wall. It is designed to reflect as much as 95% of the heat wasted through the wall at the rear of the radiator, back into the home. The best radiator reflectors on the market.

This means that your radiators don’t need to work as hard to heat rooms. Therefore, without reducing the physical temperature of the room, you can reduce the TRV setting on the radiator. This will lead to large savings on your heating bills. These savings mean that Radflek typically pays for itself within just one year!


Radflek Radiator Reflectors

Most of us use radiators as part of our heating systems. This is because they help us keep nice and warm without costing too much to heat. However, this doesn’t mean there isn’t any heat loss. For example, much of the heat radiated from the rear of the panel is simply lost through the wall.

Introducing Radflek – the revolutionary energy saving radiator reflector!

Radflek is a laminated aluminium foil that is simply positioned between the back of the radiator and the wall, which then reflects as much as 95% of the ‘wasted heat’ back into the room. This means that the radiators will not need to work as hard to warm rooms meaning that you will save money on your energy bills.

Radflek – the very best radiator reflectors – with Radstik.

Unlike DIY foils that will quickly oxidise and lose its reflectivity, Radflek has has a special coating that prevents this from occurring and  ensures its long term high reflectivity.

Improve the efficiency of your radiators

The Radflek foil is also incredibly easy to fit. All you need do is simply measure the distance between the brackets holding the panel to the wall, then cut the Radflek sheet to fit the gap between the brackets. Finally you use two Radklips to attach the Radflek to the brackets – and it simply sits there, out of sight.

We sell the radiator reflectors in a 3 sheet pack – These three sheets of foil should be enough to use on 6 normal sized radiators. We appreciate that some customers may have more than 6 radiators in their home though so we also offer bundled packs at discount!

So give Radflek a try – a true, install and forget, out of sight out of mind, solution with the potential to save you lots of money on your heating bills!

    Quick and easy to install. We have 7 medium sized rads which I think isn’t uncommon and we need 2 packs but it works well.

    Ok. I have 20 years of making my own (aluminium and cereal boxes). I thought that was ok, but then 2 years ago I read the Radlek blurb and it indicated I was not doing as well as I could. So I bought the largest pack. We have 14 radiators in a 4 bed house, of which 5 are on “outside walls”. The marketing emphasises the outside wall heat loss, but if the radiators heat any wall structure the loss may not be so great but it still goes into a wall. Anyway, all the radiators were done last year and whilst the winter was not cold, the rooms warmed up more quickly, so saving fuel. Our gas usage dropped from 20000kw/h to 16000 kw/h for no change in living style. If a half of that was down to a warmer winter the othe half (£65) was down to Radflek. From now on that becomes a 100% saving every year. If you have any doubts, go for it, BUT remember your origami skills, make a rough measurement of each radiator THEN work out how to combine the cutting to give the best usage, and cut the sheets accordingly. I still have one whole sheet left from the large pack. If you cut it wrongly just tape the wrong piece to another to match another template. Don’t work one room at a time work aim for a combination of radiators in differing parts of the home to give economy of cutting i.e. Small bathroom with large bay window. Very pleased and impressed.

    Product quotes it can do three radiators, but actually sheets are shorter than I expected, so only covered two. Advice would be to measure length of radiators. Can’t comment yet on if they work as too hot for heating at the moment!

    By far the cheapest Radflek radiator packs I have seen online. Bought myself 3 packs. Lets see how they get on this winter.

    unless my radiators are on full-whack I feel like most of the heating I pay for just goes out through the walls. This was such an easy way to stop my money being wasted!

    Ordered these to try to help my cold house last winter. They have now been in place for best part of a year and I genuinely do think they make a considerable difference. I assume other radiator reflectors work in the same way, but these are really easy to install and arrived next day. Give them a try would be my recommendation…. Cheap enough to take a punt!!

    Prompt delivery, cheapest I could find. Already had some in my house so new that they did a good job.

    Ordered before Christmas, made the living room noticeably warmer. Not too sure about payback but certainly increased comfort. Prompt delivery

    Thumbs up for ease of install. Not sure about the savings yet, but promising as I have certainly been able to turn down the TRV on the radiator.
