Heatkeeper Insulation Radiator Panels will significantly reduce the heat loss through external walls and directing the heat from your radiators evenly back into the room. This is achieved by creating an air curtain that rises above the radiator minimising the loss of heat energy produced.
Up to 70% of the heat from your radiators is heating the wall behind; the aluminized surface reflects the infra-red heat, normally absorbed by the wall behind the heater units, back into the room. The moulded shape of the Heat Reflector also traps air between the heat reflector and the wall surface creating a thermal barrier which reduces conductive heat loss through the exterior wall.
The saw tooth profile of the Heat Reflector, increases air turbulence and circulation which immediately improves the room comfort levels and reduces your heating requirements and cutting your energy bills.
Once the Heatkeeper panels are fitted your radiators will start to warm your rooms a lot quicker, the core of your heating unit is hotter, water inside the heating system will return to the boiler at a higher temperature allowing you to reduce the overall boiler water temperature to achieve the same or improved comfort levels. The reduction of the boiler water temperature reduces the amount of fuel required to re-heat the water, and will help you save money.
The insulation panels are flexible and robust and easy to fit no specialist tools required - no need to remove radiators – just apply the double-sided tape provided.
Panels can be cut to size with scissors, and cut edges overlap horizontally and vertically to fit any size of radiator. Detailed fitting instructions are included in each pack.

The benefits of using Heatkeeper Radiator Insulation Reflectors
- Energy saving and reduction of fuel bills .
- The enhanced heat distribution, reduces radiator heat up time and eliminates cold spots.
- Discolouring above the radiator is reduced.
The HEATKEEPER Energy Saving Radiator Panel is suitable for the height of the most common household radiator and the overall dimensions are 580mm high x 450mm wide x 8mm deep.
These insulation panels are most effective where the gap between the wall and the radiator is greater than 20mm, where the gap is less than 15mm you may need to remove the heater to fit the panel.
The Heat Reflector panel is made of clear PVC with an aluminized surface.
The panel is moulded with a ribbed profile that creates an insulating space when affixed to a flat surface.The Heat Reflectors are strong and durable and will not be damaged by normal handling.
Heatkeeper Panels comply with all required BS Fire and Safety requirements applicable within the EU. Class 1 surface spread of flame when tested in accordance with BS476 (Part 7: 1971, section 2) These panels are accredited by Ofgem for EEC schemes.
Test Results
“Demonstrated a heat saving, and a beneficial effect on flow pattern, due to the presence of the panel, especially when radiation is taken into account. Overall savings in the range of 22% to 27% can be expected’’.
- UKAEA Laboratory, Harwell, Oxford.
‘’It can therefore be said that the variation in output and hence reduction in losses is 15% to 13%, based upon mean water minus room air temperature from 10 to 60 degrees celsius. This figure relates to the losses through all surfaces and not just the external wall”
- BSRIA (Building Services Research and Industry Association
‘’I am pleased to report a saving of 23.7% for September and October… this result has exceeded our expectations and would indicate that the Novitherm panel provides a new method of achieving substantial savings, even in circumstances where the building fabric meets or exceeds current best practice standards”
The Queen’s University Belfast
“ Results for the period of test indicated that the Novitherm panels gave an average saving of 14.4%” -
- Scottish Energy Agency on behalve of the PSA (Property Service Authourity)
Included in the Kit
- HEATKEEPER Energy Saving Radiator Panels come with full, easy-to-understand fitting instructions and strong, self-adhesive, double-sided tape for secure fitting to the wall behind the radiator.
