ᐅ Wood-burning stove with water heating in new construction – yes or no?

Hello everyone,
I was a bit surprised that I couldn’t find a fairly recent discussion on this topic (if I missed something and unnecessarily started a new thread, I apologize).
To the main topic:
We are building a new house (solid construction, no special insulation properties) that will be heated with a heat pump.
A wood-burning stove is planned for the living room, and now we face the question: should it be hydronic (water-heated) or not?
I initially approached this with the firm belief, “of course hydronic, why not, this way the stove can also be used to supply domestic hot water and central heating.” However, feedback from the first stove installers has made me somewhat doubtful (“the extra costs are hardly compensated by the energy saved,” and so on). Therefore, I thought I’d ask here for experiences from other homeowners on this subject.
So, as the title says, hydronic wood stove in a new build – yes or no? I would really appreciate some opinions and experiences.
Best regards,
DerToni

yes, but basically I already find 26°C (79°F) almost too warm But the above-mentioned 19°C (66°F) are generally considered too cold

We have a KfW40+ house with 300m² (3,230 sq ft). The open living area on the ground floor, where the Justus Reno R stove is located, is roughly 70m² (750 sq ft).
Rooms with closed doors were around 19°C (66°F), while rooms with open doors on the upper floor reached 21-22°C (70-72°F), for example the master bathroom.
We had a period of about two weeks with the heating off and temperatures around zero degrees Celsius (32°F). We lit the stove well in the morning, then let it burn less strongly during the day, and before going to bed, we loaded it up again. We used softwood planks leftover from the construction phase. Over New Year’s, when we were away for a long time, we stacked in 6 kg (13 lbs) of lignite to keep the house warm.
The stove is not water-heated; heat distribution was only via natural air circulation through the stairwell to the upper floor and the controlled mechanical ventilation system with heat recovery.
We simply wanted to test whether we could keep the house warm in case of a blackout. And we can.
What surprised us was that even the bathroom stays nicely warm.
We collected a 10-liter (2.6 gallons) bucket of ash per week.
For a water-heated wood stove to be worthwhile, you probably need to heat even more intensely than we did—so, around 25°C (77°F) or more in the room where the stove is located. And we have a large, airy house.
