ᐅ Has the heating pipe been bent too sharply?

Hello,

The underfloor heating is currently being installed in our new build, and I noticed this bend.

Underfloor heating: white pipes in loops on insulation foil with blue tape marking.


You can feel a narrowing when you press on it.

The architect and heating company say this is fine, but I don’t agree.

Edit: Some info about the heating pipe being used: Empur Klimapex PE-RT 17x2 millimeters (approx. 0.67x0.08 inches).

Thanks in advance.

Best regards

I hired someone for all phases of the project, but for me, it basically ended around the roof and windows stage. However, that was a big mistake. Exactly three windows were installed incorrectly, and one cannot be tilted open. If I hadn’t noticed and measured it myself, it wouldn’t have been possible to fix it after plastering, and in my opinion, the architect should be responsible for checking this.

Including phases 8 + 9?

Hello,

first, just take a deep breath...

All three types of pipes mentioned meet the requirements for underfloor heating with regard to oxygen tightness.
The multilayer pipe achieves this through an aluminum core,
the XC pipe has a middle barrier layer,
and the RT pipe has an external barrier layer.

None of these pipes can be compared to those from the 1970s.

The installation is not that bad; depending on the floor plan, it can be difficult to cover large areas in some corners.
As for the bend shown, as long as there is no cloudy white discoloration at that point, I would not cut it out and replace it with two fittings; instead, carefully increase the bending radius.
And then everything will be fine.

So, an update:
The couplings were installed, but unfortunately without protective sleeves and with press fittings instead of the agreed slip sleeve connections.
Sometimes I really feel like the people on the construction site just want to mess you around; they truly do whatever they feel like.

Get written confirmation that the connection will last for decades and has been approved.

Also, put a piece of hose or something similar over it yourself.

...Decades.... well, let's just hope the tradesperson never plans on retiring
