Schütz system heating pipes
The right product for each application.

Three types of heating pipes are available for use in underfloor heating and cooling systems: duo-flex PE-X plastic safety heating pipes made of cross-linked polyethylene, non-cross-linked duo-flex plastic safety heating pipes PE-RT, and tri-o-flex® metal safety heating pipes. The three types of pipes are distinguished by long life cycles, corrosion and incrustation resistance, chemical resistance and flexibility, and are especially easy to install.
