Honestly, if a general contractor only builds according to their own ideas, even though I am supposed to pay them, they are the wrong "partner". If I pay, I want my wishes to be fulfilled. Period.
That is true, that is also agreed upon. He just offers me both options, gas and heat pump. Until now, it was basically clear for me to build with gas, I have described the reasons. But now there is the offer to pay about 3000 euros more for the heat pump and thereby achieve kfw55. That makes me reconsider. One problem then, however, is cooking if we decide against gas. We just bought a new gas stove last year, which we actually do not want to miss. And having a gas connection just for cooking isn’t worthwhile.
