ᐅ Smart home system for underfloor heating in a KfW40+ energy-efficient house?

Good morning dear forum,
We are currently building; the shell is almost complete, and the plan is to have a 165 sqm (1776 sq ft) city villa without a basement built to KfW40+ standard. Right now, we are going through the plumbing and electrical systems throughout the house, discussing various details.
There will be no wired smart home system. However, Homematic wireless will be used for the roller shutters and heating (only underfloor heating). Later, additional features could easily be added to this setup. Even a layperson like me can manage that… 🙂
Right now, I’m stuck on the heating control. Does controlling the underfloor heating manifold with electric actuators provide significant added value? Our heating installer has a clear opinion and says no! The idea is that properly setting up the underfloor heating once will yield a better annual performance factor than with smart home control. For me, that was basically a given.
By the way, the heating system will be an air-to-water heat pump. On the roof, there is a 12 kWp photovoltaic system with a 6.5 kWh battery storage. That might be relevant somehow.
What are your thoughts on this?
If you need more information, I’m happy to provide it.
Thank you very much for your feedback and best regards!

The developer told us that the ERR also respond to temperature, so for example, if a window is open, the underfloor heating will increase its output.
Our underfloor heating is supposedly considered "responsive" for an underfloor heating system.
That is how the consultant explained it to us.

There is no recognized proof of quality. However, there are hundreds of positive experiences. Since no links are allowed to be posted here and I am known for well-founded answers and experiences (and real estate has been my profession for decades), you can safely assume that an exemption from ERR is relatively easy to obtain 😉 I admire your self-confidence. Unfortunately, you have not convinced me with all of your hundreds of answers. But surely now you have your answer for that.
What would be interesting for future homeowners is a topic on real experiences with such letters regarding the waiver of ERR installation. That way, we move from your theory to practice.
If you’re building “smart” anyway, the ERR can simply be managed through the software. No one requires ugly wall-mounted thermostats for the ERR! Temperatures are simply detected via touch sensors, and the rest is handled through a visualization system. Whether you use it afterwards or accidentally delete it the next time you work on the visualization, no one cares anymore.

Pwnage61914 Apr 2022 13:00Does anyone here have experience with local or district heating and can explain exactly how it works? Also, how it functions in combination with my underfloor heating and radiators in the basement?
I know that local and district heating are quite rare.
