SpeedComfort Radiator Fan Mono Set - 1 radiator fan - Energy efficient – 2x faster heating - Up to 22% energy savings – Easy to install – Whisper quiet - Dutch product

Easy to fit, although would be great if there was instructions rather than a few pictures on the packaging. However very simply fitting with magnet design. We have a designer steel radiator which struggles to connect heat like an aluminium radiator. This has made such an improvement to the warmth and general comfort of the room, heats up quicker and tackled the cold spots. They are expensive for what they are but cost nothing to run and quick simple solution that works. Noise is minimal, as slight fan noise but no louder than the central heating anyway.

OK, let me start by saying I was doubtful about this product buy having read the reviews I thought I would give it a try. I am pleased to say that it does in fact appear to work. Let's be clear this will not make your room / home any hotter it just makes your radiator more efficient. Rather than relying on convection alone these fans give them a little boost and push her warm air around all be it very gently. Fitting is easy if a little tight on my radiator and the supplied 'sensor' appears a little skewed but still works. Noise wise I can hear the fan..... but only if I listen for it. They are very quiet and consume very little electricity.

The box came with just the plug, unit and standard clips only - fortunately this was fine for me, but should be really clear that all the extra adapters are not included. Instructions are on the side of the box itself. It's basically like having a fan heater! We have a small box room, 2.7m2 with a small single panel radiator. After failed attempts to fit as it came out of the box, I then realised for a single panel the clips need to be detached from the unit and reoriented. After this it stuck like a charm! Plugged it in to main and attached the magnetic heat sensor to the rear and off it went! It's very quite and able to work from home in that room without noise getting picked up on the mic or anything. Room not only warmed up faster but stayed warm for longer - as this is driven by heat the radiator stayed warm even after heating system turned off and so this kept blowing! Also hides away very nicely, we are fortunate to have a plug right next to the heater. Only reason it's not 5 stars is the price - £50 is a bit much for a fan heater and in reality you do save money in the long run due to it's low power; but you are running your whole home heating system vs potentially a small room electric heater for 15£ and bills being higher when you use it.

Quality feels plasticy, flimsy and cheap Size was perfect for my radiator Price even with deals is way too expensive The fans are not loud. It is noticeable when the room is quiet. Not very powerful either. But the main letdown, it does not make any difference, it does not save any money. I do not feel warmer inside the room and checked my usage and do not see any benefit using this. I have seen many videos about this product online, probably all was sponsored and payed to the testers because this is just useless. Do not bother to buy it.

I was sceptical that it would work but it really does. Ours is an old house pre 1907 and has always been a pain to heat up. Big problem was the heat just didn't travel far from the radiator. The radiator was piping hot but still the room felt cold. With the fans clipped to the bottom of the double radiator the heat has evened out nicely. The whole room feels warmer. It will definite save on bills as the thermostat for the rads is now benefiting from the dispersed heat in the room, so, the boiler isn't kicking in anywhere near as often. Prior to fitting the fans the temp on the thermostats would take all day to reach temperature. This morning it only took a couple of hours. I'm still finding it hard to believe something so simple as 3 little fans would make such a big difference, but it does. Also the sensor you clip to the rad works well. Once the rads cool down sufficiently it turns of the fans. It was so easy to fit too. It's whisper quiet. The little pup hasn't even noticed it is on.

Unit is tidy and easy to install but I expected a bit more blow from to fans. On the plus side there quite and unobtrusive

I don't think these fans will save me on energy but what it has done is circulate the heat from the radiator around the bedroom and brought the difference between the bedroom and the rest of the house from 4 degrees to just 1.5 degrees

Brilliant, it is a brilliant product. I have got that out of the way ! I have new non magnetic radiators and this is not able to magnetically attach underneath, which is a real shame as it would be completely out of sight. So I have this on top held down with a thick clear tape. So, obviously that looks terrible. However, I am now able to get my bedroom to a good temp and keep it there so I will put up with it. I have 2 of the other type designed to sit on top and they are not quiet and are bot designed for my new radiators so they are held in place with the same tape. This product is cheaper and quieter and much less obtrusive. I just wish they were USB powered and not another adaptor, they are computer fans that can run on 5v !!!!!!!
