Hello,
I am aware of the principle that with copper piping for heating systems (which should be the standard), an expansion joint must be installed every 10 m (33 feet) of pipe length. That sounds logical and I have seen it done before. My question is: Is there a standard, manufacturer’s guideline, or similar regulation that requires this? In other words, is it recommended practice or a mandatory rule? I would appreciate knowledgeable answers.

Nowadays, plastic is also used for heating systems.
At most, the section near the boiler is still metal, but that part probably isn’t longer than 10m (33 feet). Ah, okay, I didn’t know that. Here, the supply and return pipes are still made of copper. Are there major disadvantages to using plastic instead? If so, I might consider having the upper floor redone differently at some point.
Vicky Pedia25 Feb 2020 13:26I believe copper is still commonly used. In recent years, composite pipes made of plastic and aluminum have become increasingly popular.
