Installing Underfloor Heating in Old Buildings – UZIN Renoplan® Makes It Possible. Underfloor heating installation and floor fitting

The UZIN Renoplan® system provides an excellent solution for installing underfloor heating over an existing screed. Specialist underfloor heating companies can groove channels into the existing screeds to accommodate heating pipes. The UZIN Renoplan® system allows floor coverings to be installed over this type of under-floor heating system without compromising the stability and functionality of the screed. By combining UZIN PE 360 PLUS ready-to-use dispersion primer, UZIN NC 182 repair mortar, UZIN RR 201 reinforcement fleece and UZIN NC 196 fibre reinforced smoothing compound.

For the successful installation of floors over underfloor heating, the grooved channels and heating pipes must be clean.

Installing underfloor heating in the renovation of old buildings requires a coordinated approach to product solutions. UZIN offers the Renoplan® system, which provides everything needed for efficient floor installation over existing screeds with underfloor heating.

UZIN PE 360 PLUS is used as a primer to ensure strong adhesion for the subsequent layers. UZIN NC 182 repair mortar integrates heating pipes into the existing screed, resulting in a low build-up height.

UZIN NC 196 is a fibre-reinforced smoothing compound that creates a low-stress surface for the final floor installation. This enables the seamless installation of various floor coverings, including sheet vinyl, LVT, rubber, carpet, and wood.

By utilising UZIN products, challenging underfloor heating can be quick and easy.

The UZIN Renoplan® System offers an efficient, sustainable solution for installing underfloor heating in existing screeds.

Can I install underfloor heating in an existing screed without raising the floor too much?

Certain underfloor heating systems allow for channels to be grooved into an existing screed, enabling the placement of heating pipes without the need for a thick additional layer of screed. With the UZIN Renoplan system, these grooved channels are filled, after which a smoothing compound such as UZIN NC 196 is applied, along with UZIN RR 201 fleece. This creates a highly durable, low-profile underfloor heating system that is ideal for situations where height is limited.

How are heating pipes installed in an existing screed?

A specialist underfloor heating company begins by cutting precise grooves into the existing screed. They then lay the heating pipes into these channels. Next, they use products from the UZIN Renoplan® system to securely embed the pipes, reinforce weak areas, and smooth the surface, making it ready for the final floor installation.

How are UNDERFLOOR HEATING pipes safely covered in a grooved screed?

The installed underfloor heating pipes are first placed into the channels and then embedded with UZIN NC 182 repair mortar. This quick-drying, low-stress mortar is specifically designed for filling grooves and cavities. It creates a stable, well-bonded layer around the pipes, forming a secure base for the subsequent application of UZIN Renoplan® products. Incorporating UZIN RR 201 reinforcement fleece and UZIN NC 196 fibre-reinforced smoothing compound provides extra protection for underfloor heating pipes.

How can I reduce the risk of cracks over underfloor heating before laying the floor?

A fibreglass-reinforced fleece, such as UZIN RR 201, is applied over the prepared surface to help distribute stresses more evenly. When used with appropriate UZIN smoothing compounds such as UZIN NC 196, this reinforcement absorbs movement from the heated screed, reducing the risk of cracks appearing in the floor covering.

Which floor coverings can I install over underfloor heating?

Once the UZIN system has fully cured and the underfloor heating is properly commissioned, you can install a variety of floor coverings, including wood, vinyl, LVT, laminate, or carpet. It's essential that the selected covering is approved for use with underfloor heating and adheres to UZIN's product and installation guidelines.

Which products should I use to install floors when renovating older buildings with underfloor heating?

When refurbishing areas with underfloor heating in existing screeds, it's important to use the UZIN Renoplan® underfloor heating system. Start by cleaning the substrate and applying a UZIN PE 360 PLUS primer. Next, fill any grooves and embed the pipes using UZIN NC 182 repair mortar. To reinforce, apply UZIN RR 201 fleece, then smooth the surface with a fibre-reinforced compound like UZIN NC 196. Finally, install the floor covering using a UZIN adhesive, such as UZIN KE 2000 S, approved for underfloor heating, and follow the specific product data sheets for the chosen floor covering.
