Hello dear house construction forum,

I’ll come out right at the beginning: I am a complete layperson and am just trying to understand or supplement the existing planning so that in the end we have a meaningful result.
We have the following situation:
Single-family house bought from 1994. The previous owner apparently installed underfloor heating on the ground floor by themselves with a "colleague," so unfortunately there are no documents for that. In the bathroom there is a normal radiator and additionally underfloor heating, presumably from the original construction year. In the utility room only a normal radiator. In the other rooms on the ground floor the mentioned underfloor heating. There are 5 heating circuits, so far controlled via RTLs at the position of the old radiators.
We would now like to have underfloor heating installed on the upper floor as well, all controlled via a heating circuit distributor with wireless thermostats. The other radiators are to be replaced by low-temperature radiators so that the entire flow temperature can be lowered and perspectively easily converted to a heat pump.

How would it make the most sense to proceed with the situation on the ground floor and the RTLs? Ideally, we would prefer not to need these anymore and to be able to remove the corresponding valves. So far we have been told that this could be difficult since they might still be needed (so that enough heat gets to the upper floor and can be regulated down below?). Or is there still a solution without RTLs where the ground floor is simply centrally set to one temperature? One temperature for all rooms (except the bathroom, but there we would have the radiator to turn up) would be sufficient for us since the living/dining area and kitchen are all open plan anyway.
Or if it would be better to keep the RTLs: Is there a solution so that the valves are virtually "hidden" in the wall? Like inside the box? If yes, what would you recommend?
Or would it be more sensible to try to install a flow temperature regulation via the supply line now at a lower temperature and then control this with individual room thermostats via wireless?

What would you recommend?

And please excuse me if I have misunderstood anything.
Or if you need more info, feel free to reach out.

RTLs are still needed for hydraulic or thermal balancing.
