How Do Heatkeeper Panels work?
Reflective Surface
The highly reflective surface of the Heatkeeper panel reflects heat back into your room, helping reduce wasted heat.
Insulating the Wall
The moulded shape of the Heatkeeper Radiator Reflector panel creates an air space between the radiator and the wall surface creating a thermal barrier.
Better Heat Circulation
The saw-tooth profile of the Heatkeeper Radiator Reflector Panels is designed to stimulate convection currents which improve heat circulation, helping to eliminate cold spots in the room.
A simple upgrade behind your radiators
Heatkeeper panels can be cut to suit your radiator layout and fitted using the supplied adhesive tape or the Easy-Fit hanging method. Follow our illustrated guide to choose the right fitting method for your home. View the fitting guide

Which Heatkeeper pack do I need?
Start by measuring the area you want to cover behind each radiator, allowing for brackets and other obstructions.
Standard panels
Each panel measures 580 mm high × 450 mm wide. Choose from packs of 5, 10, 15, 20, 25 or 30 panels to suit your radiators.
Mini panels
Each Mini panel measures 200 mm high × 450 mm wide. Supplied in an 8-pack, they’re an option where a standard-height panel would be too tall.
Choosing your quantity
Two standard panels placed side by side span 900 mm; three span 1,350 mm, before trimming or allowing for your fitting layout. Count the panels needed for each radiator, then add them together to choose your pack.
