x-net® controls

Heating comfort at the press of a button.

Clever control for panel heating and cooling. This means the desired heating comfort can be set individually for every room. Clever control also means: Save cleverly. x-net control is available in two product lines, to precisely suit the particular requirements.

x-net® connect

Two problems – one solution.

Kermi does away with uncontrolled heat dissipation – with the x-net connect systems, heat is specifically guided past the screed in the area of the underfloor heating manifold to render an efficient and controlled heating operation possible. That way, major heat losses in this area can be prevented.

x-link® plus

The perfect connection between design radiator and underfloor heating.

The connection fitting with a white or chrome cover perfectly fits the 50 mm connection to the compact bathroom radiator.
