Invisible and Unobtrusive

Plaster-based wall heating systems spread both warmth and amazement. Embedded in thin plaster just a few millimetres thick, the heating tubes are invisibly integrated into the wall structure and emit an even heat. Plaster both equalises and distributes the heat across the entire wall surface.

Plaster-Based Wall Heating with Capillary Tube Mats

Plaster-based wall heating systems can be built very advantageously with BEKA capillary tube mats thanks to the narrow diameter of the BEKA capillary tubes, which are just 4.5 mm wide. Just 15 mm of plaster are sufficient to cover the capillary tubes. Additional reinforcement of the plaster surface is not required since the temperatures in the plaster layer are only about 35 °C and are also very uniform. Nevertheless, the wall surface heating already achieves a heating output of more than 90W/m2 with this low supply temperature. This is made possible thanks to the small distance between the capillary tubes and the surface as well as the rapid heating of the wall.

However, the installation of capillary tube mats as a wall surface heating system also requires a project-specific technical solution for integrating the 20 mm-wide distribution piping for the mats into the wall, since the plaster layer should be kept as thin as possible. The distribution pipes for the BEKA capillary tube mats are usually inserted in a wall slot. This also requires, however, that the structural effects are secured constructionally.

The BEKA capillary tube mat typically used for installation in wall surface heating systems is the P.VS20 model.

Advantages of Wall Heating in Plaster-Based Systems

  • Small additional wall construction
  • The wall simultaneously acts as an energy store
  • Suitable for various plaster materials

Plaster Wall Heating with BEKA Single Pipe Technology

As an alternative, plaster walls can also be thermally activated with BEKA single pipe technology.

This requires, however, a plaster thickness of about 30 mm, additional mechanical anchoring of the plaster layer on the bare wall and stress-relieving reinforcement in the plaster.

When BEKA single pipe technology is used as a wall heating system in plaster-based systems, the 10 mm-thick single pipes are completely embedded in the plaster up to the connection point.

Since the heating pipes for the BEKA single pipe technology are produced with diffusion-tight pipe walls, wall surface heating with BEKA single pipe technology is also excellent for thermally activating only small wall surfaces when modernising heating systems. The BEKA single pipe technology can easily be integrated into existing heating systems.


Heat Distribution with Wall Heating

Although capillary tubes are made of plastic, which in itself does not have particularly good heat conducting properties, the narrow wall thickness of the capillary tubes and the large number of heat conducting tubes more than compensate for this “disadvantage”.
