Hello everyone,

we have now been in our new house for a week. Our main bathroom is equipped with 3 heating loops in the underfloor heating. The spacing of the heating pipes is 5cm. Unfortunately, I had to notice that one heating loop does not get warm, and of all places, the one under the toilet :-(

What I have tried so far is setting all 3 heating loops at the heating circuit distributor to maximum flow, currently at 4l/min. ERR is deactivated. The room temperature of the heating itself (heat pump) is set to 22°.

What can be observed is that the floor areas in the bathroom with the other 2 heating loops are getting warm, only the tiles above the 3rd heating loop are freezing cold.
[Hausabnahme] was already done, but with the reservation that the heating itself works but the heat distribution still has to be assessed.

Does anyone maybe have an idea what I could still try? I can rule out a kinked pipe in the heating loop if I have visible flow on the respective flow meter, right?

Thanks in advance,

best regards

Here is another picture, it is about the heating loop at the very top of the picture:

Comprehension question: Do you really mean "flowmeter," i.e., an indication/visibility of an actual flow (in the sense of water moving in one direction)? Or an indicator that shows the degree of valve opening via a static water column?

Good question, these are just the standard meters in the heating circuit distributor. When you ask like that, I think it is the water column of the valve opening.

In this case, a blockage of the pipe behind the valve can indeed be possible - a column of water still remains. There would of course be no real flow, hence the question.

That would of course be a total disaster.
