Heating concept for new buildings - heat pump vs. masonry heater?

Thank you for your tips. Now I know what is probably the best economically at the moment. I will have to negotiate with my government about a fun stove.

I would never want to do without my fireplace. Underfloor heating is sluggish. You can't just quickly warm things up in the evening compared to during the day. We keep the heating at 20/21 degrees during the day, and in the evening the fireplace is heated, then it gets a pleasant 24/25 degrees. Only 21 degrees in the evening would be too cold for us. Is that economical? Certainly not, but we want to feel comfortable in the house.
