SpeedComfort Starter Set Single: Smart Heater Fan for heaters - Long-Life Heater Booster for underheaters and radiators - to Save Energy and Heating Costs

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.

Likes: Small and extremely quiet fans giving a faint breeze through the radiator from below. Options to mount magnetically (if you have a steel radiator). The device needs no set up, the fans come on when the sensor you put on the radiator gets warm and cut off as the radiator cools down. The fans use no power when not active.Dislikes: I found out that my radiator is aluminium, so the magnets don't stick and I've had to come up with a bodge to mount the fans under the radiator. The sensor is also magnetic; but a strap is supplied to help fix that to the radiator if needed.Not a dramatic increase in warmth but better than just relying on convection to warm the room.

I've moved into a property that isn't very warm, so I've been looking into ways to improve the heating. I looked into this item, and it seemed ideal. I bought a starter kit, but my radiator is quite large, so I bought an extender kit as well. The kit comes with a temperature sensor that is supposed to switch on the fans once the radiator is warm, and turn them off once the radiator cools. I've found that the fans do turn on once the radiator is warm, but then they stay on permanently, even when the radiator is cold. However, when they're on, it does help warm the room. The sound is fairly quiet, I don't notice it while watching tv. I did a quick test on power draw for a single unit, it pulled approx 0.7w. I've rated it 3 stars based on how expensive it is, and the fact that they don't turn off when they're supposed to. A basic desk fan on the floor pointed behind a radiator would do the same thing, for a LOT cheaper.

I bought this to combat a chilly bay windowed bedroom in my new house with a too small radiator which is in the wrong place. Until a new boiler and rads are fitted, this will do the job fine. Very easy to fit with ‘pop out’ magnets- takes 5 seconds, plug in and attach the heat sensor magnet to the back of the radiator. The fan kicks in when the radiator heats up and disperses the heat throughout the room more effectively. I know this works as the carpet and walls on my side of the room opposite the radiator always felt cold and now it feels warmer. Don’t expect a heating miracle, just a much more comfortable room!

Positives :-The fan was really well made with movable magnets that stuck to the the radiator easily.The fans were really quiet and only came on when the radiator was warm enough.Negatives:-Cost over £50 and didn’t make the slightest bit of difference to warming the room up ,so I sent it back .
