Otherwise, the more the things differ, the less favorable the calculation. With an air-water heat pump instead of gas, the 16 net would never have been enough, there would have been an additional 10.

That you don't want it is your decision. But that doesn't mean it is economical. Since I had a photovoltaic system planned anyway, a heat pump is the logical consequence.
