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!

How can you, for example, keep the bedroom cooler than the rest of the house? Since I’m also very interested in this topic, I started a separate thread: https://www.hausbau-forum.de/threads/lwwp-fbh-kwl-m-wrg-einzeln-raum-unterschiedlich-temperierbar.43203/ – it doesn’t quite fit with Smart Home systems...
