Easy DIY Retrofitting Wall Heating Using Prefabricated Plasterboard Panels
Replace old radiators with energy-efficient wall-mounted radiant heating
With our DIY kit, a water-bearing wall heating system can be retrofitted into plasterboard walls quickly, cleanly and cost-effectively. Low system temperatures result in energy savings compared with heating using radiators. For thermal activation, a 10 mm PE-RT pipe is embedded in 12.5 mm flat plasterboard panels. The individual wall heating elements are connected to form heating circuits using push-fit connectors and linked to the existing heating system via an RTL control unit.
This allows wall heating to be retrofitted without having to replace the entire heating system. Installation can be planned and carried out room by room. Existing radiators are removed and the exposed wall surfaces are transformed into a cosy, evenly heated wall-mounted radiant heating system.

The wall heating elements can also be installed horizontally. This may be necessary if there is limited space on the wall due to windows, for example. In such cases, a combination of vertical and horizontal elements is possible. Also wall and ceiling heating elements can also be combined. Ensure that the heating circuits are of a uniform length and that the permissible bending radius of the supply lines is observed.
In principle, installations that deviate from the standard drywall kits are possible, e.g. if there is not enough space for the standard number of drywall panels and the next smaller heating kit is too small. In such cases, it is advisable to ask our technical support team for an assessment of the planned project. We will check the feasibility of the project and put together a customised quotation.
In our experience, the 12.5 mm plasterboard is also strong enough for use in pitched roof applications. Thicker boards are not required even in damp rooms or in the wall heating version with copper pipe. As always, the manufacturer's specifications should be consulted when planning specific applications. Further information on the thermal activation of pitched roofs.
