Submit the application and get yourself exempted. I have exactly your setup when it comes to the technology and ERR would be the fifth wheel here in the house.

Exactly, you just have to briefly consider who gets this exemption application. Some clerk at the office. He then starts by researching what ERR actually means. After asking 4 employees and his boss, consulting Google and the regulatory texts, he finds out that the Energy Saving Ordinance states that ERR is mandatory and initially rejects the application.

It’s like in some offices: There is some dusty folder somewhere containing core working hours from 9 a.m. to 3 p.m. Then the situation arises that someone has to leave at 2 p.m. There is type A, who just informs his colleague briefly that he’s leaving now and that’s that. Then there is type B, who digs out the folder, asks 7 colleagues whether it’s allowed to leave earlier and if there is a deregistration form, then asks the secretariat, and tries to catch the boss to debate it with him – who in the end is just annoyed and stressed and snaps at type B, “Core working hours end at 3 p.m., and today I need them until 6!”…

Yes, that is sad, I also fear a rejection and then even more intent will be presumed.

The next economic nonsense is the obligation to install a €6000 solar system on the roof for hot water, as a penalty for gas boilers; it doesn’t pay off in 30 years, but there will be no exemption for it and it could get expensive if not fulfilled. A land of thinkers and poets...

Therefore, better a heat pump with [Photovoltaik], it pays off.

But the purchase price is also €5000 higher and the electricity price is unknown, gas is still so established in Germany, even in many public institutions, they don't quickly push the price up drastically, at least in my opinion.

For a possible retrofit via radio for individual rooms, would it be enough if there are a few 3x1.5mm cables in the heating circuit distributor? Then a control system with battery-powered room thermostats and radio valves should be easily retrofittable, right? Just in case.

The best thing will probably be to talk to the heating engineer once he is confirmed.
