ᐅ Omitting individual room control? Mechanical ventilation with heat recovery + gas heating, new build

Hello,
I am currently planning the electrical and technical installations for our new build.
We are constructing with 42.5 Poroton bricks without insulation and have planned a gas heating system as well as a central controlled ventilation system with heat recovery. Almost the entire house will be tiled, except for the children’s room and bedroom.
Now the question about the usefulness of 10 room thermostats, which would cost me €1500 gross without any self-labor, including valves and wiring, and which I find not very attractive on the wall. Additionally, there is continuous power consumption per radiator.
What I have read so far is that a hydraulic balancing is important, a well-adjusted heating curve depending on the outside temperature, and a system with a low flow temperature; then the individual rooms can be perfectly adjusted through the flow in the radiators. Due to door gaps and the ventilation system, it will anyway be difficult to maintain significant temperature differences.
I do not see what comfort the electronic radiator regulators (ERR) would bring, since the system is slow to respond anyway and would only react hours later when there is solar heat gain.
With modern gas boilers, there should also be the option to control the flow temperature externally via smartphone, for example from vacation, and thus lower or raise the whole house temperature by 1-2 degrees before arriving home.
I know that ERR is initially mandatory and you have to apply for an exemption. Do you see a chance that this will be approved? Is the architect together with the heating installer the right contact for the application? I think our installer always installs the room thermostats without considering whether they make sense.
Has anyone experienced a similar situation or has any tips or advice?
Please refrain from comments like “new build costs €500,000 but no €1500 for room thermostats,” this is about the principle of not buying something unnecessary and unattractive.

You can certainly mention the controlled residential ventilation system and calculate its benefits. However, there is often a lack of understanding because usually people involved have training in administration or business management rather than in technical fields.
I did not mention the controlled residential ventilation system because I consider it purely a comfort feature, and it has been sufficient without it. But those were different times, and nowadays it might be necessary to document everything in detail.
Since you are not applying for KfW funds, you don’t really need to worry about any hidden issues.
The fees vary depending on the local authority.

It is quite sad that some people see conspiracies everywhere and apparently let the number at the bottom right determine their lives.
If you want to contribute something constructive to the topic, go ahead, but obvious nonsense can be skipped; that way you won’t reveal gaps in understanding complex processes.Says the person who, as a moderator, simply deletes posts that don’t suit him?Only the forum operator can delete posts. I only edit and always leave a note. This often preserves the discussion thread and allows regular users to follow everything.
Only rarely, when I was involved, is the entire post removed, but even then a note is included.
See below.
P.S. Deleting posts is one of a moderator’s responsibilities. This concerns the content, not personal opinions. However, some people do not seem to understand this.
I repeat: If you have something relevant to add to the topic, please do so. Other users are also welcome to participate. If it is just about releasing personal frustration, this is not the right place.
