Underfloor Heating – The Classic Surface Heating and Cooling System
Thin-Bed Underfloor Heating – When it’s About Achieving Energy Efficiency and a Rapid Response
Underfloor heating is widely used and accepted for providing surface heating and cooling. However, unnecessarily high supply temperatures and slow response speeds owing to the thickness of the heating screed are frequent points of criticism with conventional construction methods.
This is where thin-bed underfloor heating is able to make the most of its advantages. With this technology, the heating pipes are located just under the surface and close to one another. BEKA capillary tube mats and the BEKA single pipe technology are the suitable components to use here.
Thin-Bed Underfloor Heating with BEKA Capillary Mats
The structural design of thin-bed underfloor heating systems is described in standard technical specifications for surface heating and cooling systems. If the substrate is sufficiently loadbearing, the thin-bed underfloor heating system can even be installed directly on the existing floor. This is particularly advantageous in retrofitting projects with a view to optimising costs and reducing construction time.
The thin capillary tubes in the BEKA capillary tube mats, which have an outer diameter of just 4.5 mm, only have to be covered within the structure by a self-levelling compound with a total thickness of 10 mm (that is approved by manufacturers of underfloor heating systems). The new surface finish for the floor can then be laid on this layer. The typical BEKA capillary tube mat used here is the P.VS20.
Advantages of Thin-Bed Underfloor Heating
- Low supply temperatures
- High energy efficiency
- Rapid thermal response
Thin-Bed Underfloor Heating with BEKA Single Pipe Technology
The heating tubes in the BEKA single pipe system for thin-bed underfloor heating only have an outer diameter of 10 mm. They can be installed in studded panels or clamp profiles. The underfloor heating manufacturer-approved self-levelling compound that is poured over the heating tubes only has to have a minimum thickness of 17 mm. PE-RT 5-layer composite tubing is used, which is diffusion-tight according to DIN 4726 ISO 24033/22391/21003. With a view to protecting the system against corrosion in line with conventional technology, this defined quality enables its easy installation in existing heating systems. It is precisely this material quality that makes thin-bed underfloor heating with BEKA single pipe technology highly interesting for smaller-scale modernisation projects.
If, for example, you only want to retrofit small areas of up to 20 m² or individual rooms such as bathrooms or kitchens with underfloor heating, and nevertheless want to take advantage of thin-bed underfloor heating with a low structural depth, we would recommend the system solutions provided by, for example, FLEXIRO.
Rapid response to temperature changes, very uniform surface temperatures, high specific heating capacities even with supply temperatures of only 30 °C – these are the impressive strengths of thin-bed underfloor heating
