3 Things To Remember When Decorating With IR Heating

When decorating around a heater, you may find a problem occurs that can upset the look of your home. Issues can happen with any kind of heater and we are here to help you tackle them.

Black Marks

When black marks appear above a heater, it is called Thermal Tracking or ghosting.

Despite what you may think, this is not actually caused by the heater itself.

The issue is actually the result of airborne particles that clump together and heat up before condensing on the cold surface above the heater. These particles can be from anything like fumes, ovens, candles or even car exhaust fumes from the street.

In cases where the walls are damp, as well as having the black marks, the particles can also be caused by mould forming in the paintwork or wallpaper.

Overall, this problem tends to worsen in draughty houses or damp atmospheres.

In trying to fix this, you should consult a builder or decorator. Here are a few things to try in the meantime:

  • Clean the walls regularly to improve the look. Note: this will not remove the causing factor
  • The wall should be thoroughly cleaned and insulated before a non-water-based paint is used
  • Prevent any source of draughts from entering the house
  • Use extractor fans in any bathroom and de-humidifiers in other rooms to reduce the levels of condensation

Peeling Wallpaper

Wallpaper may peel from behind a heater for many different reasons. Again, the unit itself will not be the underlying problem but can expose an issue you already have.

When wallpaper is damp, it can peel very quickly from its seam as this is where its adherence is the weakest. The main reason it will be damp is condensation. Drying clothes on radiators is a common cause of damp wallpaper which will crack around the heater’s perimeter.

Another cause of wallpaper peeling is poor surface preparation. This is because the paste is unable to make a proper bond with the surface underneath to stick properly. Not to mention if the paste is water-based or of an insufficient strength, the décor will be destroyed under the heat.

Peeling can also occur if you have papered-over wallpaper cracks. The paper underneath can still breathe and form air pockets or blisters underneath which will subsequently cause the paper to lift from the wall.

Again, we suggest consulting a builder or decorator to help you fix this problem. However, we suggest doing the following:

  • Avoid mounting a heater over any wallpaper seams
  • Use PVA adhesive to repair any small patches of wallpaper lifting
  • Move the heater to a different location to reduce or eliminate the problem


Electric heaters are not a source of water. Therefore, rooms that are damp cannot be this way because of our IR units.

If you add internal insulation in your home, this can increase the levels of damp and condensation within the space. You can combat this by applying external wall insulation.

Infrared heaters have a drying effect on the objects around them which will discourage any condensation and keep moisture in the air.

The moist air will still try to create condensation on cold surface unless you remove it, so you can use extractor fans or de-humidifiers to avoid any condensation. If you allow it to develop, mould can also form.

You can fix this issue by asking a builder to determine the source of damp within your home. Here are a few tips from us:

  • Remove damp air with an extractor fan, loft vents or a de-humidifier
