Buyer impressed by ‘how a lot sooner the room warms up’ with radiator fan

The Smartair Boost Radiator Fan is currently 10% off at Yimbly

With colder weather quickly approaching, and energy costs set to rise once again, many of us are looking for ways to keep warm without overspending on energy bills. While newer properties are designed to be as energy efficient as possible, older homes can be extremely difficult to keep warm.

That’s where devices that can help to boost warmth, like the Smartair Boost Radiator Fan which has been engineered to channel rising warmth back into the room, preventing it from disappearing through cold external walls and windows, can come in handy. Another popular option for colder homes are foil radiator reflector panels (£43.99 on Amazon for a 25m roll) – created to bounce heat from behind the radiator back into the living space, stopping it from vanishing through outer walls.

Going back to the Smartair Boost Radiator Fan, shoppers can save 10% off at Yimbly, an online shop owned by this site’s parent company Reach plc, with code AUTUMN10, reducing the cost from £49.99 to £45. According to Smartair, the energy-efficient Radiator Fan system enhances warm air circulation, heating living areas more quickly and effectively, reports Wales Online.

Describing how the technology works, the manufacturer explains: “Four energy-efficient, axiel fans drive your radiator’s heat through sealed air-conducting funnels into your room where you want and need it. use either manual mode for control or automatic mode for maximum efficiency: easily change between the two modes with the flip of a switch. Use either manual mode for control or automatic mode for maximum efficiency.”

The device costs less than a penny per hour to operate, according to Smartair, and can run on mains power or via the built-in power bank for up to fourteen continuous hours of use. It can also help speed up clothes drying by directing warm air straight onto your clothes airer, with no installation needed – simply position it on the radiator without requiring a plumber or electrician.

The unit includes an intelligent auto-shut-off safety feature – should the radiator become too hot and hit 70C, the device switches itself off until the radiator drops back to 65C. Smartair claims it’s compatible with virtually any radiator type, including double convector tubular, double tubular, single, cast iron style models, and with the supplied stability feet, it even works on single convector radiators.

Alternative radiator fan options are also on the market, such as the Speed Comfort Discrete Radiator Fan at QVC, available as a double pack for £79.96. These Speed Comfort fans have earned praise from customers, with one buyer describing it as ‘a fantastic bit of kit,’ and giving it a five-star rating in their review.

They wrote: “Small, discrete and perfect. What a difference it has made to the cold room I used to hate. There is a slight hum when it kicks in (rad has to get hot before it does it’s magic). What a godsend. I’m now deciding if to get another one for my bedroom as I do get cold. You also need a convenient plug socket near by but most rads are close to one. It has strong magnets that hold it in place on the underside of the rad. Great purchase.”

The Smartair Boost Radiator Fan boasts more than 3,000 reviews on Amazon, with customers raving about how effectively it spreads heat throughout the room. One five-star reviewer wrote: “I bought this Smart Boost to help distribute heat from my radiator more efficiently, and after using it for a bit, I’m genuinely impressed with the difference it makes.

“The biggest plus is how much faster the room warms up. Instead of heat just rising straight up from the radiator, this unit pushes warm air outward, which helps the temperature feel more even and comfortable much sooner. I also really like that it turns on automatically once the radiator reaches a certain temperature – no need to manually switch it on or off.

“Noise is minimal. I was worried it might be distracting, but once it’s running, it’s barely noticeable, even in a quiet room. I can’t comment on battery life since I keep mine permanently plugged in, but for my setup that hasn’t been an issue at all.”

Another shopper chimed in: “This is very good and useful set of fans. We have a large conservatory and had difficulty getting it warm. With this device you can set it on auto to come on when the heating does and now the conservatory can be used even on freezing mornings.

“I chose the six fan option which is good but I think for a large conservatory next time I will choose the eight fan version. You get used to the fan noise as it’s no different to any other sort of room fan. Because it’s portable with a built in battery it means you can move it to another room that might need a boost without having to have a plug nearby. Very useful and would buy again.”

Some customers weren’t impressed with the battery life, and complained the fans were too loud for their taste, with one buyer commenting: “If you are buying this because it is rechargeable and you don’t have a socket nearby, save your money. The battery life is nowhere near sufficient for a standard day of heating. However, if you have a mains socket close by and don’t mind a noisy fan, the running costs are impressively low.”

Meanwhile, another customer hailed the fan as perfect for rooms with high ceilings, saying: “It comes on automatically when it reaches temperature, it has made a noticeable difference warming the room quicker than leaving the radiator to do it itself. I live in an old building with high ceilings and find the heat is redirected straight through the fan rather than going straight to the ceiling.”
