Panel heating and surface cooling

KERMI panel heating and cooling. x-net.  Heating and cooling - customised for every application.

Invisible heat source in the winter, pleasant cooling in the summer without a draught.

Powerful and durable, x-net ensures a pleasant room climate as underfloor heating or wall heating. Suitable x-net system solutions are available for both new construction and renovation. The versatile installation options are suitable both for wet laying in the screed and for dry laying on the screed. As a result, the available knob system, clip system, hook & loop system or tacker systems can be optimally used in the private as well as in the commercial and industrial sectors.

What systems are available?

Systems without insulating materials

If you need to ensure a particularly low construction of the panel heating, you will find the perfect solution in the without insulating systems. Optionally as a clip system, as a Velcro panel, as a knob element or as a thin layer system.

Systems with insulation

If the necessary installation height is available, underfloor heating with insulation is the first choice. Insulation reduces energy costs and increases comfort.

Wall heating systems

Wall heating systems bring heat into the room via the surfaces of walls. Their low flow temperatures make them ideal for low-temperature heating systems. With solutions for new builds and renovations.

Electrical solutions

Electric underfloor heating systems are particularly suitable where no central hot water heating system is available or only a very low installation height is possible. They are an ideal solution for renovations in particular.

Industrial panel heating

Panel heating systems for commercial and industrial buildings offer optimum utilisation of the premises without the need for radiators to take up space or disrupt the workflow. In addition, the effort and costs involved in cleaning and maintaining heat exchangers are eliminated.

x-net® room temperature control

Heating comfort at the touch of a button.

The clever control system for panel heating/cooling. This allows you to set the desired heating comfort for each room individually. And clever control also means clever savings. x-net control is available in two product lines, depending on the respective requirements.

x-link plus von KERMI. Die perfekte Verbindung zwischen Heizkörper und Fußbodenheizung.

x-link® plus

The perfect combination of design radiator and underfloor heating.

The connection fitting with cover rosette in white or chrome fits perfectly on the 50 mm connection of the radiator.

x-net Wohnungsstation pro mit Dämmung versorgt jede Wohnung mit warmem, sauberem Wasser und behaglichen Raumtemperaturen durch Flächenheizung

x-net® home station

For hygienic domestic water heating and efficient heat supply.

Can be operated with all heat sources - x-net home stations ensure hygienic domestic water heating using the flow-through principle and an efficient heat supply thanks to an integrated underfloor heating manifold and direct heating circuit.

KERMI x-net connect system – the thermal image clearly shows the differences.

x-net® connect

Two problems - one solution.

We put an end to uncontrolled heat dissipation - with the x-net connect systems, heat is channelled under the screed in the area in front of the underfloor heating manifold to enable efficient and controlled heating mode. This prevents large heat losses in this area

Understanding panel heating/cooling

How does underfloor heating actually work?

The way underfloor heating or wall heating works is as simple as it is ingenious: instead of installing radiators in the room, pipelines are laid in the floor or wall, through which hot or cold water later flows. The warm water transfers its heat to the floor via the heating pipe and heats the room more evenly than a radiator. This means you can even walk barefoot in winter if you wish.

And why can it also cool?

Panel heating systems can not only heat, but also cool. If cold water is channelled through the pipelines, it draws heat from the floor or wall, cooling the room evenly and without draughts. This natural and noiseless cooling function is much more pleasant compared to conventional air conditioning systems and also achieves considerable energy savings as it requires less electrical energy. Panel cooling creates a comfortable indoor climate, which is particularly beneficial in the summer months.

Wall and underfloor heating: can it be retrofitted?

Yes, retrofitting underfloor heating is possible. We offer specialised systems that make the replacement of conventional radiators with efficient panel heating much easier. Various underfloor heating systems are available for renovations, enabling quick and effortless installation:

If the structural conditions make it difficult to install underfloor heating, wall heating systems such as x-net C21 and x-net C22 are an ideal alternative. In terms of comfort and function, wall heating systems are identical to underfloor heating systems. The decisive advantage is that the heating pipes are laid in the more easily accessible walls instead of in the floor, which makes them particularly suitable for renovation projects.

The right system

Choosing the right underfloor heating depends on various factors. Decisive factors include which floor covering will be installed later and whether it is a new build or a renovation.

There are essentially two basic systems:

  • Systems for wet installation in screed
    e.g. x-net C11 No. e.g. x-net C11 knob system or x-net C12 tacker system
  • Systems for dry laying
    e.g. x-net C13 dry system e.g. x-net C13 dry system

Did you know?

Even the Romans appreciated the benefits of warm floors. Their so-called hypocaust systems worked according to a similar basic principle to modern underfloor heating systems: Warm air circulated under the floors, heating the rooms. A fascinating example of how good comfort is timeless!
