The Uponor Minitec system is the ideal hydronic underfloor heating solution for renovation projects. Using a specialised PEX-A pipe measuring only 9.9 x 1.1mm, Minitec can be installed over an existing slab. The pipe work is laid within a thin adhesive sheet and is then covered with a self-levelling compound. Using the Minitec system as your hydronic under floor heating method means the existing floor is raised only by around 15mm (excluding floor coverings).
