What are Heatkeeper Radiator Reflector Panels?

They are an inexpensive energy saving reflector panel that fit behind radiators, providing a fixed and permanent energy saving feature for your home.

How They Work?

Unlike the loose hanging flimsy versions, Heatkeepers radiator reflector panels work in three ways to save energy, money and improve the comfort and feel of your rooms.

Insulating the Wall

Radiator Panel Insulation Pockets

The moulded shape of the Heatkeeper Radiator Reflector panel creates an air space between the radiator and the wall surface creating a thermal barrier.

Reflective Surface

Heat Reflection from Heatkeeper Radiator Reflecttor Panels

The highly reflective surface of the Heatkeeper panel acts as a radiant agent and reflects heat back into the radiator, which returns the water to the boiler at a higher temperature, therefore the heating system requires less energy to reheat the water in the boiler.

Saw Tooth Profile

The saw- tooth profile of the Heatkeeper Radiator Reflector Panels are designed to stimulate convection currents which improve heat circulation, helping to eliminate cold spots in the room.

What are the energy saving benefits?

Depending on the insulation features of the property (e.g. wall/loft insulation, double glazing), independent scientific studies show that HEATKEEPER® Panels can save as much as 20% heating costs where panels have been fitted to all the radiators in the home and will pay for themselves within the first year of fitting.
