Radiator Booster - cut heating bills and make your home warmer (as seen on Dragon's Den)

A Radiator Booster is an innovative, lightweight product that uses a small fan to draw heat from a standard radiator, gently distributing it better into the room. It will warm a room faster, save lost energy, and reduce heating bills.

Simply place a Radiator Booster on top of a hot radiator, holes facing down, and plug it in. It'll heat a room in up to half the time, allowing the boiler to shut down sooner, saving heating time and cost - for a running cost of about 30p a year!

It's adjustable in size, has a built in thermostat and could save an average household between £70 and £140 per year.

In-built automatic thermostat - the internal fan only comes on when the radiator reaches 32 degrees celsius, eliminating the need to turn the unit on and off manually, making it very energy efficient

Telescopic adjustable size fits smaller and larger radiators - from 400mm up to 750 mm or indeed anywhere in between, matching most radiator sizes

Fitted with one, powerful, quiet fan (see below)

Estimated to save an average household between £70 to £140 on heating bills per year

Radiator Booster 3 metre extension lead available: here.

Directions
Place the Radiator Booster ontop of your radiator with the diamond shaped holes facing down. Plug in. Once the radiator has reached 32 degrees celsius, the booster's fan will kick in to suck warm air up, and push it out through one end.

A Radiator Booster can improve efficiency by as much as 50% - the clever fan arrangement distributes heat more evenly around the room, in addition to reducing heat loss through the wall behind your radiator, allowing your boiler to shut down much sooner.

Cold spots can be dramatically reduced and in many cases eliminated. Room warm up times are typically reduced by 50% and thermostats can usually be set 2 degrees lower. Overall a significant energy and cost saving.

If you could save just one hour a week of your boiler working, you would save 15 kilowatts of power. You could easily find the savings more than this, between 7 and 14 hours/week (over 100 kilowatts) during the colder months.

Please Note

32 degrees celsius is the radiator temperature NOT the room temperature. A typical radiator contains water at 70 to 90 degrees celsius when hot.

With radiators that have not been bled for some time it may take a little longer for the Radiator Booster to kick in. If that is the case, and your radiators need bleeding often, a radiator auto vent might be helpful.

Frequently Asked Questions:

Why doesn't my Radiator Booster come on when I switch it on?
There's a thermostat inside the Radiator Booster which means the fan only comes on when the radiator reaches 32 degrees celsius. This makes it very energy efficient. If the fan came on when the radiator was not warm, cold air would be pushed round the room... which would defeat the object! (NB 32 degrees celsius is the radiator temperature NOT the room temperature. A typical radiator contains water that will be heated to 70 to 90 degrees celsius when hot.)

How much energy does it 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 £49/year or 10% of your heating bills. Most tests carried out with Radiator Booster have achieved more than 2 degrees reduction.

Can it be used with Radiator Covers?
YES. 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’ its heat, relying solely on ‘convection’. Radiator Booster enhances that convection at least three fold, distributing huge amounts of trapped heat.

Can I leave it running 24/7?
YES. As the new Radiator Booster 2 has in built thermostat that switches on at around 32 degrees Celsius and switches off when the radiator temperature drops below this point. However, we would recommend that you turn the device off at the wall socket when not needed, as the power supply runs continuously and therefore continues to use electricity when switched on.

Could I plug it into a timer unit?
Yes. You can use it with a standard timer.

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

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

Can I use it 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 Radiator Booster.

Can I use it 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 it use, and is it safety approved?
The Radiator Booster has been tested and approved by an independent laboratory. Each fan is rated at less than 1 watt, and each unit is supplied complete with a full set of instructions. Should you operate a Radiator Booster for 500 hours, it should use approximately 1kWh of electricity (less than 13p for most homes).

Will I need to put one of these 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.

My nearest power socket is a long way from my radiator.
Each unit comes fitted with a 1.8metre power lead, which should suit most situations - you can always add an extension cable, or a extension lead.

Do I need to clean the device?
Yes. As with any fan, dust will build up on various surfaces, which will seriously impair the performance and reliability of the device. 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 it working?
YES. The small fan used in Radiator Booster, like any fan, make a 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 most 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.

Sometimes it 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.
