krischaaan8 Apr 2018 17:01Hello experts,
In our new build, the underfloor heating pipes have now been installed. However, in some areas (especially in the corners), the pipes are suspended in the air... The pipes are under tension and are lifting the installed Flipfix panels.
Our underfloor heating manifold for the ground floor is located in the basement, meaning all pipes run through a shaft down to the basement. Here, the pipes rise quite sharply and are under tension... Is this acceptable?
In the corners, I believe the screed presses everything down. At the shaft near the manifold (where the pipes need to bend 90 degrees downwards), it is almost impossible to press the pipes down with force.
Is it allowed for a gap to remain here? Is this standard practice?
Or how can the pipes be firmly fixed to the floor?
Best regards,
Christian

Most likely, an angled fitting should have been installed for each pipe at the shaft transition. I wouldn’t apply any pressure there at all. Have a look at the datasheet for the hose you used; it should specify the minimum bend radius. From what you’re describing, I suspect it wasn’t respected. In that case, I would recommend ordering a work stoppage.

and what does that mean?
and what does that mean?
This means that if you form a circle with the pipe, this circle must be ten times the diameter of the pipe. Such a circle has a certain curvature. If you do not form a full circle but only bend the pipe around a curve, the pipe must not be bent more sharply in the curve than in your circle.
Get an expert involved as soon as possible; to my ears, this does not sound good at all.

As long as the bending radius is appropriate, you can secure the corresponding sections accordingly.
But actually, it mainly depends on having the properly sized opening to guide the pipes neatly to the next floor...
