Planning of heating technology

Hello, we are planning our detached single-family house (approx. 140sqm living space + approx. 20sqm hobby room). Now the question arises regarding the heating technology. Currently, I tend to go for a gas condensing boiler with ordinary radiators. Solar for water heating will also be installed. Additionally, a chimney for a wood stove on the ground floor is to be built. What holds me back from heat pumps of any kind are the enormous additional costs, which, together with underfloor heating for the entire house, amount to approx. 18,000 - 25,000 euros. I would be grateful for different opinions.

We have already considered various options for our new building. The manufacturer recommended an air-to-air heat pump to us; an air-to-water heat pump was also considered at one point, as underfloor heating would be better. The costs were never the main focus in our decision against a heat pump, because with an air-to-air heat pump we would have even received a bonus. In any case, we are currently planning a pellet system, supported by solar energy. Additionally, a stove with a water jacket in the living room that could possibly support the underfloor heating. And also a ventilation system. We decided on pellets to be able to stay within the Kfw55 standard. The possibility of receiving a repayment subsidy was quite important in our considerations. Maybe that could be something for you too?
