This Is How It Works: Do-it-yourself Wall Heating with Ready-to-install Drywall Panels

Installation instructions

The FLEXIRO dry construction wall heating is a system kit designed for the simple, quick and clean conversion of existing wall surfaces into panel heating and integration into the existing heating system.

The ready-to-install plasterboard panels with integrated 10 mm heating pipe, plug-in connections and connection to the existing heating system via RTL boxes make the installation of water-bearing wall heating a rewarding project for do-it-yourselfers and installers. The following illustrations show the main installation steps of our drywall system in a test installation of approximately 3 m². Detailed installation instructions are supplied with the kits.

To conclude

Despite the simple design of the wall heating system and the ease of installation, we must point out that, as the manufacturer, we can only guarantee correct delivery from the factory and not installation and connection by third parties. Please also observe the current standards and regulations for heating systems.

FLEXIRO wishes you every success with the realisation!



For the FLEXIRO wall heating dry construction, a standard gypsum plasterboard 12 mm thick is used. For damp rooms, dry construction recommends an impregnated gypsum plasterboard GKBI. Please ask for a customised offer.

Yes, the FLEXIRO wall heating can be mounted on an exterior wall. However, the exterior wall should have a maximum U-value of 0.30 W/m2K. If insulation is installed behind the wall heating to minimise heat loss to the outside, a building physics check of the construction may be required to prevent condensation in the wall when the wall heating is not in operation. During operating, the wall heating will dry-heat the affected wall rather than causing moisture damage to the construction.

After installing the drywall panels, you can visualise the arrangement of the heating pipes in heating mode with a thermal imaging camera. The pipes have a distance of 100 mm. In this way, pictures can also be hung later. Alternatively, if the walls are not tiled, you can spray them slightly damp when the heating is on. Where a heating pipe runs, the moisture will dry off more quickly.
