I’m taking a risk by naming numbers here, but I’ll do it anyway. Calculate about 10k for gas with collectors according to the Energy Saving Ordinance, about 15k for the heat pump plus 10k for the photovoltaic. So about 15k difference. The photovoltaic pays for itself after about 12 years. Heating costs are cheaper with gas, but photovoltaic helps you here. I think you can consider it equal. So 5,000 euros left over. You can do that if you have the budget. Based on the numbers, I rather don’t see that for you.Hello, sorry for only getting back now. What is meant by energy level? Budget for the entire construction project 350-400k (land available) size approx. 250m² (so nothing for flat-plate collectors) Well, as often, a bit of everything. Cheap heating, good for the environment and somewhat self-sufficient would also be nice. But yes, I hadn’t thought about the costs yet, can you make a price comparison modern gas heating vs. photovoltaic + air-water heat pump? I have no idea yet, what, say 10,000 vs. 25,000??? Then you have to think carefully about how much the "environment" is worth to me, because for a 15,000 difference I can heat with gas for a long time. And yes, my budget is very tight.
