Radiant Wall Heating for Plastering Methods

Plaster wall heating regularly amazes room users. Where does the heat that is perceived as natural come from? The heating pipes are invisibly integrated into the wall structure in a layer of plaster just a few millimeters thick and emit an extremely even heat. The plaster takes over the heat distribution over the entire wall surface. In many projects, wall heating is installed as a supplement to ceiling heating or underfloor heating in order to guarantee the required heating output.

Wall heating plaster with capillary tube mats

Due to the small diameter of the BEKA capillary tube mats of only 4.5 mm, wall heating can be implemented in the plaster system without applying a thick layer. A plaster thickness of just 15 mm is sufficient to cover the capillary tubes. An additional reinforcement of the plaster surface is not required, as the temperatures in the plaster layer usually do not exceed 35° C and the heat distribution is very even. Nevertheless,the plaster finish of the radiant wall surface heating already achieves a heating output of more than 90 W / m2 with a low flow temperature. This is made possible by the small distance between the capillary tubes and the surface. A dynamic control behavior is another advantage.

However, the installation of a capillary tube mat as wall surface heating also requires a project-related technical solution for arranging the 20 mm thick trunk pipework of the mat on the wall, because the plaster layer should be kept as thin as possible. The main pipes of the capillary tube mat are usually laid in a wall slot provided for this purpose, which makes structural assessment of the static effects necessary.

Reasons for the plastering procedure

  • Little additional wall construction
  • Good thermal conductivity, high efficiency
  • The wall is also an energy store
  • Gypsum plaster, clay plaster and lime plaster possible

Wall heating plaster with single pipe technology

Alternatively, wall surfaces can also be thermally activated with the BEKA 10 mm single pipe technology using the plastering process.

However, the recommended plaster thickness is around 30 mm and requires additional mechanical anchoring of the plaster layer on the raw wall as well as reinforcement in the plaster. When using the single pipe technology as wall heating in the plaster system, the 10 mm thick single pipes lie completely in the plaster and are routed through the plaster up to the connection point.

Since the 10 mm PE-RT heating pipes are manufactured with a diffusion-tight pipe wall, this version of radiant wall heating is particularly suitable for the subsequent thermal activation of small wall surfaces in the course of a heating modernization. The single pipe technology has the advantage that it can be easily integrated into existing heating systems.

Installation of wall heating plaster

The low wall thickness of the capillary tubes and the large number of heat-conducting tubes overcompensate for the low thermal conductivity of the polypropylene used. The result: high heating and cooling performance.
