Hydronic Underfloor Heating

Schlüter-BEKOTEC-THERM

- Low height wet underfloor heating system (20mm before floor covering)
- Minimal screed volumes equal low screed mass and reduced structural load
- Studded system panels reduce shearing tensions within the screed
- Short construction periods, aiding project progression
- Compatible with renewable energy sources
- System design service available

Low construction height

Schlüter-BEKOTEC-THERM can be specified with heights starting as low as 20mm before floor covering. This means that the system is suitable for both new-build and refurbishment projects.

Material and weight savings

The BEKOTEC-THERM system is considerably lighter than conventional heated screeds. A reduction of 37mm in screed thickness saves 3.7m3 of screed mortar (equivalent to a 7.4 ton saving over an area of 100m2).


The small screed mass and proximity of the heating pipes to the surface means that the system is quick to respond, and therefore more energy-efficient.

Low tension screed construction and crack-free finish

The system is based on the Schlüter-BEKOTEC family of lightweight modular screed systems. The studded pattern of the panels prevents buckling of the screed; this in turn avoids the build-up of tension. As a result, no screed joints are required in a floor assembly using the BEKOTEC system.

Paired with the Schlüter-DITRA 25 uncoupling membrane, the system prevents stresses from transferring to the covering. The overall result is a long-term crack-free finish.

Short construction periods

The four weeks that a traditional screed takes to dry and cure are reduced to just 1-2 days when using BEKOTEC. The DITRA 25 uncoupling membrane can be installed as soon as the screed is ready to bear weight, followed by the tile or stone covering. These factors result in quicker progression and less disruption to the project as a whole.


When it comes to putting the system into operation, warm-up heating can be started at 25⁰C and increased by 5⁰C per day until the desired system temperature is reached.

Compatible with renewable energy sources

Reduced screed mass means that the system can run at lower temperatures of around 30⁰C (vs. up to 50⁰C with traditional screeds). The lower supply temperatures mean that the system is a great match for renewable energy sources, such as ground and air source heat pumps.

System Assembly Options

Wet Underfloor Heating System with Dry Screed (Heights from 52mm)

With Panel BEKOTEC-EN/P

For use in new-build projects where low screed height qualities are a primary concern. Polystyrene panel is easily cut to length with a utility knife, making for rapid construction. Includes 20mm integrated insulation as part of overall height build-up.
Wet Underfloor Heating System with Flowing Screed (Heights from 52mm)

With Panel BEKOTEC-EN/PF

For use in new-build projects where achieving a level screed with minimal labour is an important factor. Polystyrene panel features foil coating to prevent absorption of the self-levelling screed, and is easily cut to length with a utility knife for rapid construction. Includes 20mm insulation as part of overall height build-up.
Wet Underfloor Heating System with Dry or Flowing Screed (Heights from 31mm)

With Panel BEKOTEC-EN F

Crossover system suitable for use in new-build and select renovation projects, in combination with either dry or flowing screed. Installed in partnership with an insulation layer of own choosing.
Wet Underfloor Heating System with Integrated Sound Reduction (Heights from 31mm)

With Panel BEKOTEC-EN FTS

Sound reduction properties make this system ideal for first and second floor use, as well as over sub-floor constructions of timber. Sound reduction capabilities of up to 25dB.
Wet Underfloor Heating System for Renovation Projects (Heights from 20mm)

With Panel BEKOTEC-EN FK

For use in small-scale renovation projects and extensions, as well as new-build projects where a particularly low height build-up is required.
Dry-Pack Screed

BEKOTEC-DPS

Easy to install dry-pack screed with extremely low tension, for interior and exterior use. Specifically developed for creating floating screeds (and bonded screeds) for Schlüter-BEKOTEC systems.

Self-Levelling Screed

BEKOTEC-SLS

Flowable self-levelling screed with extremely low tension, designed exclusively for use in interior spaces. Specifically developed for creating floating screeds for Schlüter-BEKOTEC floor assemblies.
