HAT System: Renovate floor heating.

Renovating an old underfloor heating system means prevention. Between 1970 and 1990, underfloor heating systems made of simple plastic were often installed, which allow a strong oxygen diffusion. The resulting silting and age-related embrittlement lead to reduced heating performance over time. If you wait too long, leaks may even occur. With the HAT system, your floor heating system is sustainably renovated. Inexpensively and without construction site. In advance, our professional condition analysis provides you with a sound basis for decision-making.

Refurbish drinking water pipes

Tap water enjoys an excellent reputation in this country, and rightly so. What is delivered by the waterworks is of the highest quality and can be drunk without hesitation. This quality must be preserved over the last few meters, i.e. in the building. Because the pipes hidden in the masonry are not immune to aging. With ANROSAN, we sustainably renovate old drinking water pipes from the inside. The cement coating we use is unique worldwide.

Makes every floor a heater

Floor heating systems are very economical, pleasant and hygienic heating systems that are suitable for almost any building. Thanks to a revolutionary milling-in method, we can use the milling-in technology to mill floor heating systems directly into cementitious subfloors - dust-free and with low emissions. The single-milling technology also impresses with low operating costs and high energy efficiency.
