Underfloor heating pipe frozen in the slab

How do they feel about you stepping into their construction and managing things. Now they can blame you if something goes wrong.

Yes, it's a problem. But otherwise, I would have had to sit idly by and let the pipes freeze and burst... Not so fun.

I also hope that the loop that froze survived. I think I've read that they can sometimes survive even if they've frozen.

And who put the crushed ice there? Jätten Gluff-Gluff? Bert Karlsson? I don't know what they will say when you tell them you've removed ice from the pipes.

But what do you want to achieve? A new pressure test?

Yes, I want a new pressure test.
Then it was like this: I wrote on Monday and complained to the company that they hadn't emptied the pipes of water and that it had frozen in the loop.
They replied that it couldn't have frozen due to the reasons I mentioned in the posts above.
So now I want a third party to tell them that they're out to lunch.

Contact the company and describe the incident and explain that you have helped them as the situation could have worsened if the ice had remained. Request a new pressure test and the result from it will indicate if further measures are needed.

Thank you for the advice, everyone.
I talked to a concrete station today, and they said that it's only the first few days that a concrete slab generates any heat worth mentioning.
They said that if it was -5 on Sunday, then the slab was also -5.

I have informed the construction company of this information, we'll see what they respond. It gets pretty tiresome; how can they be so uneducated and ignorant? They probably think the Earth is flat too...

The unfortunate thing is that they made mistakes on a couple more things, for example, they filled deep pits in the foundation with clay - clay as a bearing layer - brilliant!!

Sounds like a bunch of amateurs who don't really know what they're doing. I would make sure to follow and document the process carefully.

Does the contractor mean that the floor heating manifold that is ABOVE the concrete won't freeze either? Why even let water into the system in the first place?

Does the contractor mean that the floor heating distributor ABOVE the concrete doesn't freeze either? Why even let water into the system in the first place?

No distributors etc. are connected. Just hose in the slab that goes into the basement. Will be connected later.

He had water in them for pressure testing and left the water during casting. Apparently, it's suitable to have water in them during casting.

and if it now starts healing and you have been there and worked on it yourself, it probably won’t help much if there is a leak
