Product details

Radiator Booster

• Heats your room faster - saving energy and reducing your heating bills
• Running costs of around 30 p per year
• This is the Mark3 latest version
• Works with any conventional water filled radiator
• Sucks warm air from behind the radiator and fires it into your room
• Reduces heat loss through your walls
• Heats your room quicker - central heating shuts down sooner
• Sits either on top of or behind your radiator
• Supplied with a 1.9 m mains power lead

The Radiator Booster is manufactured from rigid, recyclable plastic and blends easily into any room. At its heart is an efficient fan to gently move the warm air
around the room, which mixes the entire air in an average room every 90 minutes. With intelligent electronics, the Radiator Booster only circulates the air when the radiator exceeds 30 degrees Celsius, so ensuring no energy is ever wasted.
When the Radiator Booster technology was independently tested by Which Magazine (April 2011), they concluded the following:
"Our test lab found that with the radiator booster fitted, the room heated up more quickly, the thermostat needed to come on less often and energy consumption dropped"Please note that the Radiator Booster is not designed to work with oil filled, electric storage or electric convection radiators, it is designed for use with standard domestic water filled radiators as part of a central heating system. The Radiator Booster should not be used in shower rooms, bathrooms or other areas exposed to damp or humidity.

Rated 4 out of 5 by from It's good, but it's not Carling! It works! Mind you, it depends what you want it for. I can't believe that it saves you money unless it is placed in the same room as the system thermostat, then it might. What it IS good for is ensuring a room, or a hall way in our case, is thoroughly warmed from a poorly placed radiator. Previous comments on the small size of the fan and the quality of the materials used are justly made considering the advertised price. Far too expensive, however it does the job and has noticably warmed up our hall way. I am considering purchasing another for our conservatory, but only if the price comes down significantly

Rated 5 out of 5 by from Brilliant bit of kit I bought one of these a few weeks ago and installed it in the living room. This is a north facing room with a full width and somewhat elderly double glazed window, and has always needed an additional blast from an electric fire as well as the water filled radiator to bring the temperature to a comfortable level. With the radiator booster sat on top of the rad, the room is now nice and warm without the electric fire on. A simple and clever enhancement of the radiator technology.

Rated 5 out of 5 by from Why it so good I have 2 radiator boosters, had one of the early models which is still running well. Definitely heats up the room quicker and feels warmer all over. The cost to run is about 50p per year so effectively nothing. I think people need to understand that this is NOT a fan heater but a way to mix the cold spots in a rom with the warm air from the radiator giving a warmer all over feel . Its not the prettiest product but definitely effective.

Rated 3 out of 5 by from Good points Bad points I have two of these and have had for a couple of years now. They are not cheap for what they do, however they do help circulate the air if a radiator is in a position that some heat is lost. They one thing that lets them down is they are quite noisy. I am unsure if they can be quietened or not, but the constant noise is quite irritating.

Rated 5 out of 5 by from Understand how it works Enough to make a cat laugh ! Some users of this product have a very poor understanding of how radiators work and accordingly can't get a grip on the radiator fan usage.Because a poster thinks he can make his own up for far less than they are sold at doesn't denigrate how the product works, if they can make their own I'd encourage them to do so. The description of this product is correct, a small (ish) plasticated tube with slots in the bottom which has a telescopic smaller tube which pushes inside it (on earlier models) which allows a degree of tailoring to the radiator size ( 14" up to 26" approx). It has a small computer sized fan in the end. It doesn't matter if it's on a larger radiator it still works to good effect, and the effect is ...increased and better convection behind the radiator. The small computer sized fan in the end works on milliamps which is good for low cost running (it's that reasonable less than £10 a year for me), but bearing in mind it's only 60mm dia the volume moved is like a hamster wheezing ! but hears the rub...it doesn't need to be any more volume ! The increased flow from behind the radiator increases and encourages the natural convection greatly, and the reason it helps your bills come down is that because the room temperatures goes up more quickly with the increased flow, the thermostat for the central heating reaches it's operating range quicker and maintains the temperature easier using less power. Fan equipped radiators work in the same manner but cost loads more to buy than this, and their fans are much more costly to run. On the radiator booster once the in fan thermostat has tripped at about 30 deg to turn them on the fan will continue pushing out the hotter air from behind or within (if a two panel radiator) a radiator even if the central heating turns off until it stabilises at room temp. It's not pushing out cold air, it's moving air that may only be slightly warmer than the room temperature, that's how convection works and would happen even if the fan was not working. The noise level from the small fan in use is about the same as a computer fan (no surprise there, it is one !) but the Rad fan case may need moving or "tailoring" with self adhesive draught excluder foam to prevent it vibrating against the rad, not as big a deal as some posters make. If the fan gets noisy in use clean the fan blades with a cotton bud, sometimes the dust build up on them causes it to resonate, in my book normal maintenance. In use they allow rooms which have natural convection problems to achieve and maintain a warmer environment at less cost and they impressed me enough to buy three of them which are still in use and so far have lasted 5 years with no problems. Oh...and as a final comment Which magazine ( a neutral non biased professional consumer organisation) who have a substantial research budget set up to examine products describe it as one of the few products which work to enhance room heating at reduced cost. Now who would you like to believe, them or badly opinionated members of the public ?

Rated 1 out of 5 by from Don't waste your money Bought to help heat conservatory with idea of blowing warm air from radiator around the room to help get rid of the ambient coldness you get in winter from windows. Very disappointed - arrived in old packaging that had been torn at the end, the plastic end caps on the preformed plastic shell were a light pink as opposed to white like the main unit, and as per other reviews the fan at one end of the unit is not even as strong as a PC fan. Even at the sale price of £20 this is over priced junk. It made no difference at all, blowing heat about 3" away from the unit at one end only.

I have a single radiator to which I'd like to attach a fan blower (Radfan)to distribute the heat off the radiator more effectively. But, models illustrated only show double radiators. Is there one made suitable for a single radiator? Thanks

Asked by: Allan
Unfortunately we are unable to comment on items we don't stock, but I can confirm our model would be suitable as it is designed to fit either on the top of the double panel style or on the fins behind a single panel style radiator.

Why can't I just put it on top of a radiator that is two panels with small gap? It sounds ideal for what I need, what difference does it make, surely the radiator with a grill is two panels that are covered with the grill top? Can I buy a grill ?

Asked by: Sally
Installation advice can be found on the manual in the downloads tab, if you do not install the unit in any other way it may not be as effective.
