I am developing my attic (about 50 m2) and I am bored with my heating. I have oil heating with hot water circulation and I have two pipes (round trip) waiting in my eaves. So I just have to connect. The problem is this: two craftsmen recommended me to do my installation copper, but a large DIY area advised me to use the sheathed PER much easier to install for a novice like me. I want you to know that my pipes will be on the ground in the unused sub-slope. What do you think?
It is always better to play homogeneity (copper / copper). You can use the PER but in principle behind a dubbing.
