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

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.

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

Great item and very good.value, the metal edge bends a bit too easily so needs to be handled carefully, if your radiator has the metal grill too that hides the gap it may need to be removed.so the fan sits correctly, as I found it wouldn't sit without a concern it may fall off. The magnet didn't reach the metal. Despite this im going to order another as this one works very well on bathroom radiator. Nothing to assemble, easy to charge vattery, looks good and not to big.

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.

Very good item

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.

Lieferung: Die Air Booster kamen pünktlich an und die Verpackung war unbeschädigt. Allerdings war bei einem der Stecker ein Zinken abgebrochen. Beschreibung: Es wurde leider nicht darauf hingewiesen, dass das Produkt UK-Stecker besitzt und damit für den EU-Markt ungeeignet ist. Bedienung und Support: Keine direkte Bedienungsanleitung vorhanden. Das Gerät aber auch nur zwei Kippschalter, man kann also nicht viel falsch machen. Für Hilfen und Erklärungen wird auf eine Internetseite verwiesen. Dabei handelt es sich um die Haupt-Webseite eines Internet-Shops. In diesem Shop sind zu den Geräten weder FAQs noch Hilfen zu finden. Leistung: Trotz spürbarem Lufstrom konnten auch zwei Geräte in Dauerbetrieb nicht einen 24m² Raum innerhlb von 5 Stunden auch nur um 0,5°C erwärmen (getestet mit digitalem Tisch-Termometer im Zentrum des Raumes). Ein Gerät befand sich dabei zum vergleich der Akkulaufzeit im Low-Modus, das andere Gerät im High-Modus. Lärm: Low-Modus: Vergleichbar mit einem Ventilator. High-Modus: Vergleichbar mit dem Betreib einer laufenden Spülmaschiene. Insgesamt: Definitiv aushaltbar. Wer sich in einem Arbeitszimmer konzentrieren muss oder in einem Wohnzimmer einen Film oder eine Serie schauen möchte, könnte sich allerdings gestört fühlen. Akkulaufzeit: Beide Booster wurden mit 80% Ladung gliefert. Nach 5 Stunden besaß das Gerät mit Low-Modus noch 32% Restladung. Das Gerät welches im High-Modus lief noch 14%. Fazit: Kaputt geliefert. Lückenhafte Artikelbeschreibung, fehlender Support, ungenügende Leistung.
