Smart Air BOOST Radiator Fan - Portable Radiator Fan - Cordless, Rechargeable & Automatic - Heat Sensor - Improve Heat Distribution & Circulation - Compact Heat Booster - Reduce Energy Wastage

My radiators are directly below the windows in my home so my hot hair just goes straight out of the window vents so I bought this after my son had mentioned them. It does make some sound but less than most fans, I've not tried the thermostat control or anything yet but it's really nice to be able to direct the heat from the radiator into the room at last. It's quite energy efficient because you can warm the room faster but you do have to be careful to remember to turn it off as the radiators cool otherwise it starts blowing cold air around the room, I know that should be obvious but I didn't think about it until I was already feeling the cold. It seems to be of good quality, doesn't look bad and even though it's a touch small on my radiator it still sits there and does it's job well.

Really impressed so far. Yes the fans are a little noisy on full speed but that’s not unexpected. Made a real difference to heating my living room as radiator right under window and thick curtains. Noticed the difference within a few minutes Hrest in big radiators, have a couple of not so deep double radiators and need to look at how to secure the unit as the magnet is something of a non event in them, not tried the clips that come with them yet so will try tomorrow. The automation works well so far. One star off as really good but not perfect for double radiators that are less deep.

I wish i had found this product years ago, as my bedroom had been cold for yrs when putting the radiator on, this smartair does wonders, so glad i saw a Ad for it...heat blows out from the side of it into your room, inatead of upwards, now am nice and cosy in my bedroom, it does make a nosie from the fans when on, but the noise doesnt bother me, its not that loud, if your putting your heating on before bed to heat the room up, the noise wouldnt bother you

I bought one of these for use in our kitchen. We have a long kitchen with only one radiator positioned at one end: Without the fan the end by the radiator eventually gets warm, but the other end seldom does in winter. This fan comes on and goes off when it should, and when set to "high" actually does a really good job of quite quickly - I would say within half an hour - making the whole room warmer. But there are two issues with it: Firstly, the fans have to be set to high for it to be effective, as our kitchen is quite large. This means that it sound like a jumbo jet coming in to land for long periods of time. More an annoyance in a kitchen but would be a show stopper in a living room. Secondly, the battery is next to useless. It only seems to hold enough charge for about half a day's use on full power. This isn't such a big issue for me as the radiator is near a mains plug, but again would be a deal breaker if you're buying it just to use on battery power. In summary it does what I want it for, but it's noisy and would be next to useless without nearby mains power.

Excellent fan kit for circulating heat around the rooms great service Can make vibration noise through radiator suggest foam draught excluder

This heats the room up faster so you use less power. It does have an automatic temperature switch that when the radiator gets to a certain temperature it switches on. The only thing is it stays on until the heater goes below the switch on temperature before it switches off, that means it’s blowing cool air into the room until then. It’s easy to move from room to room and simple to use. I just switch it on and off as needed.

Work really well at moving air around the room and stops cold spots. I love the automation activation and on the lowest setting its not too noisy. It looks very smart on the radiator and matches the colour perfectly. Really well made. I've brought another on since for my mom's house, she also loves it.

Bought this for my bedroom. Despite having a wide radiator under my window, the room stays ice cold and we are not aware when the radiators come on. The fan came securely packaged with brackets, adaptor and instructions. Two brackets are included to secure the fan onto the radiator. Adaptor allows you to charge the fan. Although the wire is short, the fan is portable (good for me as my mains is far away from the radiator). Two switches present on right hand side. One for low-high setting, other switch between automatic- manual. Automatic setting- fan comes on when radiator temperature reaches 35 degrees celsius. On first impressions, the fan was easily fixed to my radiator. I chosen the automatic setting, and fan came on after 30 minutes. Switches off automatically after 15 minutes. However, 1 second of 'loud whirring' occurs after it switches off and reverts back to the original fan noise (unsure whether this is expected). Low mode- definitely quiet (makes it worthwhile when radiators come on in the morning and my sleep is not disturbed). I would say the fan needs charging after 3-4 days of working. To put into perspective, our heating comes on twice daily (6am-7am and 5pm-6pm). I have given three stars due to the following: -Charging takes at least 3 hours. -The fan sometimes does not come on and I have to override to manual mode. In summary- a great product which circulates hot air around your room (definitely the bedroom feels much warmer as I don't get mould around windows and don't require a blanket in addition to my duvet), but charging and thermostat need improvisation.

Vorig jaar reeds een exemplaar gekocht en was hier blij mee. (geleverd met een snoer met Europese stekker of Eurostekker) . Hierdoor kocht ik dit jaar er nog één, maar werd nu geleverd met een snoer met Engelse stekker !!! Dus adapter nodig.

Funciona bien. Todavía estamos probando si supone un ahorro en la calefacción. No es demasiado ruidoso.

Passt gut auf Heizung. Aber keine Deutsche Beschreibung kein Deutscher Stecker.

👍

Highly recommend, this gadget will save you money on your home heating costs.
