An underfloor heating installation leak is highly unlikely. Any potential damage to an underfloor heating system normally occurs during the installation process, where the underfloor heating pipe gets accidentally cut or damaged. UFH Wales use the toughest pe-rt al pe-rt pipe and test our systems before, during and after the installation. Only fully pressure-tested systems are commissioned. However, in the unlikely event that someone accidentally damages the pipe, for example by drilling through the floor, the damaged pipe can be repaired.
