Plastic pipes are sensitive to high temperature, especially polyethylene and polyvinyl chloride. More resistant to hot water are polypropylene pipes. The fact is that with periodic temperature differences, and therefore expansion and compression, compounds of plastic pipes lose their tightness. Therefore, for a heating system with a boiler or boiler, plastic pipes are better not to use or use polypropylene. Pipe mounts can be bought on MUPRO website.
