Hi guys. I'm getting the radiators installed in my property now and I'm struggling between plastic and copper pipes to radiators. I've asked 2 plumbers and they said opposite opinions. The first one said only copper pipes is allowed into radiators, and the second plumber agreed to install plastic ones. Is there a difference in terms of safety and durability? Is the first plumber being too conservative or the second one negligent?
Looking forward to your opinions, ta
Frank
