Radiator Booster MK3, do they work?

Is this a prime example of a so-called eco and energy saving product that is misleading? How can a fan connected to the top of your radiator save you £140 per year? Doubtful! There’s a clue in the name ‘radiators’ they work by radiating heat – hot air rises, no moving parts needed, simple! According to the PR video made for this product it expels trapped air, now I’m confused, where is this air trapped? Hot air rises, that’s how radiators work, why do you need 1.5 watt fan to do this! Saying you could reduce your room temperature by 3°C by adding one of these Radiator Boosters is optimistic! How many Radiators boosters would you need?

We’re all for energy saving innovations, but will a radiator booster really do much more than make a noise, and create for more CO2 emissions in it’s manufacture and distribution than it will ever save! My advice would to make a draught excluder out of an old pair of tights and save yourself £25!  This is exactly why we don’t promote eco and so-called ‘energy saving’ products, just to make money!

    Force-cooling radiators could be used to increase system efficiency, when combined with a condensing boiler, by reducing the temperature of the water returned to the boiler, in the coldest weather. There are many UK homes where radiators originally specified for a non-condensing boiler (nominal 10 deg. C flow/return difference) are now combined with a condensing boiler, for which they would be regarded as under-sized. With good thermostatic controls (TRVs, etc) condensing will be achievable in mild weather on such a system, but on the coldest days the return temperature may exceed 55 deg. C and the potential 11% (gas, 6% for oil) efficiency benefit from condensing is lost (all the water from combustion condenses in the air just outside the house!). Under these conditions, Radiator Boosters might save more energy than they consume.

    Radiator Booster simply uses a FAN (30p/year running cost) to increase air-flow from a Radiator. NO magic science here, just moves the heat from the radiator into the room quicker. Electric bar fires were replaced many years ago with FAN HEATERS; The clue is in the word FAN!

    Heated air does indeed RISE but only slowly and straight to your room ceiling. Many people want heat around their bodies, NOT across the ceiling so they invest in a Radiator Booster which directs much of the heated air from a radiator ‘sideways’, helping to STIR the air in a room, reducing cold floors and hot ceilings.

    Finally, whilst a radiator ‘radiates’ heat into a room, the rear directs its heat onto the wall behind which is then partially lost through the wall structure using conduction. Radiator Booster attempts to save some of this heat by pulling it up from behind the radiator and directing it into the room.

    But please, if you are in any doubt, do not buy this product until a trusted friend or colleague recommends it. By that time they will be able to show you how much you could have saved.

    I read your review/blog with interset. I assume that you have not tried the product ? If you had you would feel the benefit within a few hours and understand that the Radiator Booster draws warm air away from the radiator and mixes it with cold air in the room. This creates an even warm temperature and eliminates cold spots. This is turn leads to the thermostat not needing to be set so high. Try it – they work. An average of 2 degrees is usually achievable.

    Any way if its not for you then don’t buy it, don’t feel warmer and don’t save money ! 100,000 are already in use, so the inventor must be doing something right.

    • Ross says:

      All this device is doing is turning a convection into a forced convection (like an fan heater) a 1.5 watt fan would have very little power to direct the heat any distance before the heat raises again – especially as it directing heat to the side of the radiators – rather than out into the room. At no stage is this product generating any heat, apart from its transformer and the electric motor. Therefore it is reliant on the perception of heat rather than actual heat gain, which a thermostat responds to.
