I was offered 14x2 PEX-c by a master installer, and this pipe is still "recommended by all major manufacturers."

I myself would always choose at least 16x2 and actually only aluminum composite pipe. How do you see this? Which pipe do you recommend for underfloor heating in new buildings?

What is your opinion on the discussion about necessary or unnecessary individual room control in KFW-40 new buildings? Legally clearly prescribed, but technically questionable, in my opinion.

ERR: Trying to apply for an exemption would probably be the only legal option, especially together with [KfW-Förderung]. 16/17 pipe is cheap and standard. Why discuss over 14 pipe?

I will leave KfW aside and will probably install actuators (NO) so that I could theoretically control them. Since I am planning a KNX house, that would also be practically possible, even though I will probably deactivate the actuators at first.
