Harris reports that "reductions in the overall energy consumption of the [test] room of up to 6% were recorded by installing [plain] foil behind a radiator, while the heat loss through the area of wall immediately behind the radiator fell to less than 30% of the original value".
High-quality radiator foil, like the options offered by Orange Packaging UK, reflects up to 95% of the heat back into the room, maximising warmth and energy efficiency.
A Radflek sheet placed between the radiator and the wall will reduce the amount of heat being wasted in heating the wall by reflecting at least 95% of that heat back into the room. This means less energy is needed to heat the room to the required temperature.
Insulating your water tank and radiators is a quick and easy way to save money on your bills. Insulating behind your radiators helps keep your home warmer and insulating a hot water tank helps keep the water hotter for longer.
Excellent product. Very Quick dispatch. You get about five metres of it and just cut it to size, slide it down the back of your radiator, and it now reflects the heat from radiators back into the room rather than seeping through your walls. We can now have the heating on less and save a lot of money over time.
Customer reviews
It retains heat effectively by reflecting it inwards, making rooms warmer faster and allowing them to reduce heating usage for longer. The product is considered good quality and ideal for its intended purpose. They find it simple to fit behind radiators and consider it a worthwhile purchase.
Likewise, a thin layer of insulation or reflective foil will lower the wall temperature. A layer of tile will act as a thermal mass and may reduce the peak temperature at the surface of the wall but will cause the wall to be warmer for a longer time.
Radflek is also the most efficient radiator reflector approved by Ofgem (The UK's energy industry regulator) for its Carbon Emissions Reduction Target scheme (CERT). A sheet of Radflek will save an average of 8.9 kg CO2 and up to 83 kWh of energy per year.
SRP's reflector directs nearly 100% of all energy from the tube into the space, and is the most efficient reflector in the industry.
The size of this product is 0.6m x 5m and 3mm thickness. It can meet the needs of most radiators, and the high-quality reflective insulation effect can maximize energy efficiency. Mesure your radiator and your foil. Cut the foil according to handles of the radiator.
Radiator reflectors will also reduce the energy needed to heat your home. Case studies have shown that a three-bedroom house with 5 external wall radiators can show more than 20% improvement in radiator efficiency by using radiator reflectors and save as much as £10 per square metre!
Placing foil behind radiators can reduce heat loss, making the radiator more effective and saving you money.
Radiator foil and radiator heat reflector foil are essential materials for improving energy efficiency in homes. Designed to reduce heat losses by reflecting heat back into the room, these foils are highly effective when placed behind radiators.
They took a lot of manpower to build, and it was difficult to create a balance of heat throughout the home. And you couldn't zone it like you can't hot water. Then hot water became more popular because it gives us more control over the temperature and allows you to heat your home more evenly.
A gas central heating radiator system can never be 100% efficient because the whole system uses pipes to pump the hot water around your home. Even brand new boilers are only able to be about 92% efficient, whereas electric radiators will turn 1 kWh of electricity into 1 unit of heat, making them 100% efficient.
The Cons Of Aluminum Radiators
Cost - In terms of the cost per radiator and how many you'll need to heat your home. A more traditional radiator will only need a single source to heat a room, multiple might be needed for larger spaces to get the most out of an aluminium model.
In summary, the answer is yes; when installed appropriately, foil positioned behind radiators functions effectively.
Radiator foils reflect radiant heat back into the room. They help to reduce energy loss and save you money on your annual fuel bill. Rooms may feel warmer after installing these foils so you could always turn down the thermostatic radiator valves. Only install this product behind radiators located on an OUTSIDE WALL.
If designed well with plenty of space for the warm air to travel through, a radiator cover shouldn't reduce the efficiency of a radiator and could even improve it if the cover has a reflective backing. However, a poorly designed radiator cover will trap heat and increase your energy bills.
The amount of heat reflected back will depend on the radiator reflector you use, but Radflek and SuperFOIL Radpack are regarded as the most efficient – these brands claim that 95% of this lost heat can be reflected back into the room. Radflek says a single sheet could save nearly 9kg of CO2 and up to 83kWh per year.
An often overlooked yet highly effective roof and wall insulation solution. If you are interested in saving money on your energy bills and making your home more comfortable, multi layer foil insulation is a great option.
