Retrofitting Underfloor Heating in Old Buildings – UZIN Renoplan® Makes It Possible. Substrate Renovation with Underfloor Heating
Retrofitting underfloor heating in old buildings can be a real challenge, especially with existing screed. How can an efficient underfloor heating system be installed in the screed without significantly altering the floor height? The UZIN Renoplan® system provides a simple and effective solution to this task. This system offers a sustainable solution that integrates perfectly into old buildings without compromising the room height.
How can underfloor heating be retrofitted into the screed? With the combination of UZIN PE 360 PLUS, UZIN NC 182, UZIN RR 201, and UZIN NC 570.
With the UZIN Renoplan® system, we offer an ideal solution for retrofitting underfloor heating. First, the existing screeds must be prepared by getting them ready for the heating pipes and, if necessary, milled. After the precise preparation of the substrate, the UZIN Renoplan® system ensures efficient integration of the heating systems without compromising the stability and functionality of the screed. For retrofitting underfloor heating in the screed, the combination of UZIN PE 360 PLUS ready-to-use dispersion primer,UZIN NC 182 stable leveling compound, and the self-leveling compoundUZIN NC 570 is particularly suitable. These products are perfectly coordinated.
Advantages of the System
- Minimal Installation Height: The slim thickness of the products allows for retrofitting underfloor heating without significantly affecting the floor height.
- Easy Installation: The straightforward handling of the products ensures a quick and uncomplicated renovation of the substrate, even in more complex old building renovations.
Over 250,000 satisfied craftsmen in more than 25 countries rely on UZIN systems.

The UZIN Renoplan® System – Step by Step to Successful Installation
For a flawless renovation of the substrate with underfloor heating, a clean screed with milling grooves and integrated heating pipes must be present.
Step 1: Vacuum Thoroughly
Remove dust, dirt, and loose particles with the WOLFF VACUCLEAN 2 industrial vacuum cleaner. This powerful vacuum helps to clean the substrate and ensures a strong bond for the subsequent layers.
Step 2: Prime the Surface
Apply UZIN PE 360 PLUS evenly and thoroughly to the prepared screed using the codex X-Spray or a nylon plush roller. Avoid puddling. The moisture-resistant dispersion primer reduces the absorbency of the substrate and ensures uniform adhesion of the leveling compounds.
Step 3: Attach edge insulation strips
Install UZIN Edge Insulation Strips B along rising building components to avoid sound bridges and ensure effective decoupling. This prevents noise from being transmitted through the walls or floor.
Step 4: Filling with stable filler
Use a stable leveling compound such asUZIN NC 118 or UZIN NC 182 to cover the milled pipes. These repair compounds are nearly stress-free and ensure perfect embedding of the heating pipes in the screed.
Step 5: Intermediate Priming with UZIN PE 360 PLUS
Repeat the priming step with UZIN PE 360 PLUS. This ensures optimal adhesion of the next layers and protects the substrate from moisture.
Step 6: Install UZIN RR 201
Apply the UZIN RR 201 fiberglass reinforcement fleece evenly with an overlap of 1 cm across the area. The fleece is crack-bridging and absorbs vibrations and expansions. It accommodates any arising forces and prevents cracks in the final layer.
Step 7: filling with UZIN NC 570 or UZIN NC 580
Level the area with a self-leveling compound such as UZIN NC 570 or UZIN NC 580. These products ensure an even surface. Note that UZIN RR 201 must be covered with at least 5 mm of the leveling compound.
Step 8: Laying the floor covering
After the leveling compound has completely dried, you can install the desired floor covering – whether it’s parquet, laminate, elastic, or textile flooring – on the prepared surface. The screed provides a secure foundation for the underfloor heating and ensures long-term and efficient heat distribution.
UZIN PE 360 PLUS – the Ideal Primer for Underfloor Heating
We offer the perfect solution for retrofitting underfloor heating in old buildings. The UZIN Renoplan® system with the moisture-resistant primer UZIN PE 360 PLUSensures excellent adhesion of the leveling compounds and reduces the absorbency of the screed.
Thanks to the fast drying and easy application, you can quickly continue with the next layer of work. UZIN PE 360 PLUS is suitable for all absorbent substrates. This provides the ideal basis for underfloor heating.
The Perfect Interaction of UZIN Products for Underfloor Heating Projects.
Renovating old substrates and retrofitting underfloor heating in old buildings require a coordinated product solution. UZIN offers its Renoplan® system solutions, providing everything necessary for efficient floor installation.
UZIN PE 360 PLUS serves as a primer for strong adhesion of the subsequent layers. In combination with UZIN NC 118 or UZIN NC 182, the screed is optimally prepared. The integration of heating pipes into the existing screed ensures a low build-up height, with minimal impact on the existing room height.
The leveling compounds UZIN NC 570 or UZIN NC 580 allow for a self-leveling and stress-free surface for the final floor installation. This enables the seamless installation of elastic and textile floor coverings as well as parquet.
Thanks to the synergy of UZIN products, challenges in floor renovation with underfloor heating are efficiently addressed.
