Hello everyone,
I had a chance to take a look at our heating plan on the construction site. The subcontractor’s subcontractor will be installing the underfloor heating next week.
Now to the question:
Do you see any major mistakes here, or just things that could be quickly clarified with the tradespeople on site?
Generally, I don’t have much say regarding the underfloor heating, so I wasn’t involved in the planning. However, I hope to work out one or two minor details directly with the workers on site.
So far, I’d only try to convince them to install the underfloor heating beneath the bathtub as well (acrylic on screed / showers are embedded in the screed). Or is making a last-minute adjustment a bad idea because it could mess everything up?
Any other tips? Should I try to negotiate anything about spacing?
Thanks a lot and best regards
KingJulien

Larger pipe diameter → more water volume → higher flow rate and lower pressure losses → less work for the circulation pump → heat pumps prefer a generous flow rate...
Also, I’m a bit old-fashioned → copper pipes and, for example, Vixxx press fittings and the necessary pressing tools are pretty much standard for any average heating engineer or at least readily available...
There are thousands of brands of aluminum composite / PE pipes from various wholesalers like Rehau, Fränkische, Prineteo, and so on. If you’re unlucky, your general contractor might install something exotic in your house that your regular heating engineer doesn’t know, and if it gets really bad, they might have to rent expensive special tools just to change two fittings...
Copper pipes and fittings can be found everywhere. Even if an exotic fitting system was installed by the general contractor, I can just cut out the fitting and press a transition fitting to my usual trusted system if needed...
I’m just old-fashioned: what the builder doesn’t know, he doesn’t use...

The manifolds are already installed and active, and the heat pump is running on standby. I think the opportunity has passed.
But then I'd rather just stick with the bathtub. Depending on the manufacturer, there are also manifold extension kits available to add 1-2 heating circuits, but the distribution cabinet must have enough space to accommodate them...

I believe the benefit of having more space compensates for the pressure.
You already have several loops with length/pressure variations.
