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

ludwig88sta13 Jan 2020 10:37I can confirm what has been written so far. That’s also what I was told.
At first, I thought, “That sounds great, supporting the heating system, especially in winter when you light your fireplace more often.” But the cost, effort, and cleaning clearly make it uneconomical.
When choosing a fireplace, you should also consider that it is not too powerful (especially in modern, well-insulated houses with underfloor heating or similar). As has been mentioned here several times, every component (heat pump and also the stove) should be well matched to the house’s (energy) demand.

Just as an idea, with temperatures just below zero, I have at least 19°C (66°F) in every room of my 300m² (3,229 ft²) house when the stove in the living room is blazing. Even after two weeks.
Condition: the living room is then at 26°C (79°F)... the rest is regulated by the controlled ventilation system with heat recovery.
