Moinsen, I will soon have to eliminate water damage on my Knaus Azur. Because I have to expand some of the interior equipment anyway, I came up with the idea to realize an underfloor heating in my own building. My idea is to install a double floor and “to tap” the existing Truma-Vent pipes and in part to conduct the warm air into the cavity. The lattice should then be designed in such a way that it is also a kind of guide system. Question: H at that someone has ever been built like this, can give suggestions and tips?
