The Radiator Booster Mk 3 is the latest generation of this ingenious concept. It is a clever idea that increases the efficiency of your central heating by using a small fan to suck the warm air from behind your radiator and blow it into the room. As the room heats up more quickly than by natural convection, your boiler can switch off earlier, saving you energy and money. Yet the Radiator Booster should cost as little as 30 pence per year to run.

Radiator Booster heats your room faster and saves you money

The ingenious Radiator Booster works in 2 ways:
1) Your central heating boiler can use up to 15 kilowatts of energy every hour. The clever fan arrangement within the Radiator Booster draws heat from your radiator, heating your room in up to half the time, allowing your boiler to shut down much sooner. If you could save just one hour a week of your boiler working, you would save 15 kilowatts of energy. With just this saving, the radiator Booster would pay for itself in just 10 weeks. But you could easily find the savings more than this, between 7 and 14 hours/week (over 100 kilowatts) during the colder months.
2) As your radiator heats up, the back surface normally radiates heat onto your wall, heating this up, which in turn is lost through the wall structure due to conduction. The Radiator Booster sucks most of this wasted heat and fires it into your room, significantly reducing the losses, saving you even more energy. It really is as simple as that!

How much energy does the radiator Booster really save?
This will depend on how you use the Radiator Booster, and for how long. But UK energy providers state that reducing your thermostat setting by one degree Celsius could save the average home £70/year or 10% of your heating bills. Most tests carried out with the Radiator Booster have achieved between a 1 and 3 degrees reduction, giving a saving of around £140 per annum (based upon Energy Saving Trust 2009 data).

Can the radiator Booster be used with Radiator Covers?
YES. Definitely. Provided you can fit the device in place under your cover, you will save up to 3 times as much energy. Covers prevent a radiator from "˜radiating "TM its heat, and instead rely solely on "˜convection "TM. Radiator Booster enhances that convection at least three fold, distributing huge amounts of trapped heat.

Can I leave it running 24/7?
YES. The new Radiator Booster Mk 3 has a built in thermostat that switches on at around 30 degrees Celsius and switches off when the radiator temperature drops below this point. You could turn it off when the radiator cools down but it is not necessary as the thermostat control will automatically control the use of the integral fan. If you prefer you could plug the power supply into a standard "˜event timer " unit to avoid remembering to turn it on/off.

My radiator is very long. Do I need to use two Radiator Boosters?
You can do, but it is not necessary. The simple movement of air created by Radiator Booster will normally lead to good convection in your room.

Where should I place the Radiator booster  on my radiator?
For best performance, place the Radiator Booster as far to the back as possible and centralised along the length of your radiator. However, if you place it to one end, it should still work adequately. On some radiator designs you will find that the Radiator Booster will drop down slightly behind the top of the radiator. This further enhances the performance.

Can I use the radiator Booster on oil filled radiators, electric storage radiators, or electric convection radiators?
NO. These types of radiator reach far higher surface temperatures than water filled radiators. These higher temperatures will distort and damage the housing and fans of the Radiator Booster.

Can I use ithe Radiator Booster in my bathroom, shower room, sauna room, outbuilding, etc?
NO! Radiator Booster must not be used in a damp or humid environment under any circumstances.

How much electricity does ithe Radiator Booster use, and is it safety approved?
The Radiator Booster has been tested and approved by an independent laboratory, and conforms to all aspects of CE Certification. Each fan is rated at 1.25 watt, 12v DC, and each unit is supplied complete with a full set of instructions. Should you operate a Radiator Booster for 500 hours, it will use approximately 0.625kW of electricity (costing less than 13p for most homes).

Will I need to put a Radiator Booster in every room?
We would recommend you place one in each room that you regularly use, but it shouldn't be necessary for other rooms. After all, you could unplug and move one very easily if necessary.

Do I need to clean the Radiator Booster?
Yes. As with any fan, dust will build up on various surfaces, which will impair the performance and reliability of the Radiator Booster. You will need to clean it periodically using a lint free cloth. Take care with the fan blades as they are very delicate and can break easily.

Can you hear the radiator Booster working?
YES. The small fans used in Radiator Booster, like any fans, make an audible humming noise. The fans used in Radiator Booster are similar to those used in home computers and operate at around the same audible level. During the summer many of us use large noisy desktop/ pedestal fans to help keep us cool, and in the winter noisy electric fan heaters to help keep us warm. Radiator Booster costs virtually nothing to run and is considerably quieter than either of these. The Radiator Booster also has an LED to tell you what it is doing - signalling red to confirm that the mains power is on, green to show the fan is active and flashing green to show that the radiator is cooling down.

Sometimes the Radiator Booster is quieter than other times. Why is this?
The fans can take some time to settle down and perform at their optimum, and they are also very sensitive to temperature. The sounds will vary from time to time, but this is normal and should cause no concern.
