Underfloor heating milling system
Underfloor heating: The milling system
The milling system is the ideal solution for property owners who want to retrofit underfloor heating and want to avoid an expensive core renovation of the screed. Unlike other systems, the channels for the underfloor heating pipes are milled into the existing screed using a floor milling machine. Thanks to milling machines with powerful dust extraction systems, this is even possible in occupied properties without any problems. Once the heating pipes have been laid, the previously milled channels are immediately sealed with a leveling compound or adhesive. This means there is no need to replace the screed and the room height remains unchanged. Once the leveling compound or adhesive has dried, the new floor covering (e.g. tiles, laminate or parquet) can be laid. Read this article to find out what other advantages the milling system offers and exactly how the laying and installation process works.
Good to know: Although the installation of panel heating with a milling system is primarily suitable for existing properties and old buildings, it can of course also be installed in new buildings. Feel free to make an appointment and let us advise you without obligation.
Advantages of the milling system
- Quick and cost-effective retrofitting: As the heating elements in the milling system are integrated into the existing screed or concrete floor, installation takes less time compared to stud or stapler systems.
- No change to the screed height: As the underfloor heating pipes are milled into the existing floor and only covered with levelling compound or special adhesive, there is practically no change to the screed height.
- Optimum heat distribution: The low overlap of the heating pipes allows the heat to spread better. This has the effect of warming rooms more quickly and also helps to save heating costs. - Virtually dust-free installation: A lot of dust is usually stirred up during milling. To prevent this, modern milling machines are equipped with powerful vacuum cleaners that suck up the dust on the spot.
- No influence on the statics: In contrast to other panel heating systems that have to be laid in wet screed, there is no increase in the weight per unit area when the heating pipes are subsequently milled in.
Laying and installing the milling system
Milling in the underfloor heating takes relatively little time. If present, the first step is to completely remove the floor covering (e.g. tiles, carpet or laminate) (including any adhesive residue). If there is any unevenness or damage in the floor, this may need to be evened out before milling. The screed is then carefully cleaned.
Once everything is prepared, you can start milling the heating circuits. An experienced specialist slowly moves the milling machine across the floor, observing the distances previously specified in the installation plan. An integrated vacuum cleaner ensures that no dust gets into the air and settles on windows or furniture. Once the heating circuits have been milled, the pipes can be laid and connected to the heating circuit manifold. A pressure test is then carried out to ensure that the underfloor heating is tight and that no water is leaking. If this is successful, the milled holes can be sealed. After drying, the underfloor heating is ready for use and work such as laying the final floor covering can follow.

Questions and answers about the milling system
In principle, it is possible to retrofit underfloor heating in almost any floor. These include mastic asphalt screed (AS), anhydrite screed (AE), cement screed (CT), dry screed and even ceramic or natural stone tiles. Depending on the nature of the floor, however, different methods, tools and machines (dry or wet systems) are used. We would be happy to check the floor condition of your property. Simply contact us and arrange an appointment.
Yes, low-cost loans and state subsidies can be applied for from the KfW and BAFA for the retrofitting of a panel heating system in a milled system. Information on the exact conditions and the amount of funding can be found on the KfW and BAFA portals. We will be happy to inform you about the possibilities of a subsidy in a non-binding consultation.
In addition to a floor condition suitable for milling, the screed should have a minimum height of 35 to 40 mm. On request, we will be happy to check whether these requirements apply to your screed. Make an appointment online for a free consultation.
