Wall heating in the old building without insulation


The wall heating offers many advantages over conventional radiators. Above all, energy can be saved. However, there are also some significant disadvantages. Especially in old buildings, these must be weighed. This applies even more if the old building is without insulation. Whether you can install a wall heater in an old building without insulation and where the disadvantages lie, you will find below.

Our heaters work according to these principles

A conventional heating works on the principle of convection. The air in the room is heated. The problem: starting at a room temperature of 18 degrees Celsius, more energy is needed for every degree of heat at least six percent more. But there is another principle of heating:

  • convection heaters
  • radiant heating

Radiant heating differs significantly. Here, the room air is not heated. Rather, illuminated bodies and objects are heated. If you are illuminated by a wall heating and feel that as a temperature of 21 degrees, is actually only 18 degrees geheit. The savings in energy costs are also corresponding.

The wall heating in the old building

Therefore, the wall heating offers almost for an old building in which convection heat escapes very quickly. But as a radiating surface large areas are needed. In addition, the wall must be insulated. Although a wall heating could also be mounted on an inner wall. However, then radiates cold from the outer wall. The problem with a non-insulated old building: heat is radiated outwards over the façade. So insulation must be mandatory.

Wall heating in non-insulated old building in dry construction

Alternatively, you can insulate the outside wall with drywall elements. Then you can also install a wall heater. However, humid air must be able to diffuse, so expert advice should be sought.

First insulate, then wall heating, since already the insulation saves money

The situation is different if you already know that the facade of your old building is to be insulated. However, it would be preferable in any case, first make the facade insulation, as you already saved a lot of money in a conventional heating, but not in a wall heating in a not yet insulated old building.

Tips & Tricks

The wall heating can also be installed by experienced DIYers themselves. How to install a wall heater yourself, you can read here in detail.
