Wall heating - the construction


The wall heating is increasingly used. Reason enough to deal with it in more detail and weigh up advantages and disadvantages. In the following guide you will learn everything about the construction of a wall heating and just to the advantages and disadvantages.

The different heating principles

The wall heating is a heating principle that has been used for many centuries already in large tiled stoves. Even further back is a corresponding use of the Romans, who heated walls and floors. The advantage of these heaters is that they are due to a different heating principle. The following heating techniques are basically differentiated:

  • convection heaters
  • radiant heating

Functional principle convection heating

Conventional heaters with radiators work as convection heaters. The air is heated. The circulating air then heats the entire room. However, heat is rising upwards, which also happens with the warm room air. From a room temperature of 18 degrees Celsius, each degree of additional heating costs six percent more energy.

Operating principle radiant heating

On the other hand, a radiant heater does not heat the air in the room, but rather bodies and objects that it encounters. This can be used as direct heating or for heating storage elements, which in turn emit heat. Especially in old buildings, the wall heating can clearly demonstrate its advantages, if some important points are considered.

In principle, the wall heating is a further development of the underfloor heating. Only that the side acting radiant heat is perceived as pleasant. The wall heating has so compared to the underfloor heating this significant advantage.

However, the arrangement in the wall and the heating principle itself lead to another possible disadvantage: window surfaces significantly reduce the possible area of ​​wall heating. Before a wall heating asked furniture are heated, but not the room. So these aspects have to be clarified. In particular, large window surfaces cause that must be avoided on interior walls. However, these are mainly delivered with furniture.

The construction of a wall heater

Basically, the structure is so simple that even home improvement can build a wall heating itself. A distinction is made between prefabricated elements that are used in dry construction and heating coils, which, like the underfloor heating in the screed, is integrated wet into the plaster.

The finished parts can be integrated in conventional drywall panels or in precast concrete parts. Under the wall heating must be a thermal insulation, so that the heat is not emitted to the outside. The plaster should contain as little as possible cement (less than 1 percent), as it hardens particularly strong and thus can be detached from the wall over a large area. Therefore, primarily lime, silicate, gypsum or clay plasters are used.
