Hidden heating pipes + joints?

[totte67]

Hello!

Can waterborne heating pipes (in this case they appear to be galvanized) be installed hidden in the wall? They are spliced with compression fittings (built-in, not accessible) and have no protective pipe on the outside?

Additionally, they are screwed (visible) to copper pipes in two places.

The question is not really about whether it is advisable or allowed according to current building codes.

Grateful for an answer!

If you talk water damage with your insurance company, you will likely get the answer that it's not okay. It should be continuous pipes, like Prisol pipes. That is, a copper pipe surrounded by a plastic casing, drawn from one (visible) connection point to another.

Hello!

Thanks for the response.
Yes, for domestic water pipes, it is as you say, and it is stated in BBR as well as in the "Säker vatten" industry regulations.

But does the same apply to heating pipes? Are there equivalent industry regulations for these? Other posts on the forum seem to indicate that it is allowed.

Well, the plumber where I shop said it was okay to splice pipes for the heating system hidden. But he could be wrong.

If you use MApress-type compression fittings they are type-approved. But those are copper pipes. Galvat seems a bit strange.

Talked to my plumber, and he also referred to some type of compression fitting that made it approved to splice kv/vv inside the wall.

Hidden joints on domestic water systems are not approved by insurance companies, regardless of the type of connection. However, it is okay to have hidden joints on the heating system.

Hmm, my company then just refers to BBR, anyone know where to find anything about this in the "BBR bundle"?
