The worst service, the arrogance of the staff. 2 days after installation, we flooded the neighbors and their equipment flew. They argued with foam at the mouth that it was our fault, although we did not climb there at all, they did everything themselves, we did not even touch it. So much money was invested in this underfloor heating and eventually broke down a day later. They refused to do it for us, we had to call another company. I am very sorry for the future customers of this company.
