What’s annoying is that you all think everyone else is an idiot who wouldn’t act the way you consider right. In complete ignorance of the actual reasons many homeowners build, do you ever skim through the forum? Go to the financing thread. It’s often about: Can I even afford a house? Like in real life. Why are so few electric cars sold? You definitely save consumption costs with them. Definitely. Because they are too expensive to buy. Yes, there are other reasons, but for most people the purchase price is too high. Period. Economic long-term considerations irrelevant. Payback consideration secondary. Someone posted a table earlier showing that a 12kwp system produces on average 700kwh in winter. It’s nothing for you. It’s actually a counter value of over €800 in those 4 months, but for you: It’s no use! Yield in summer? Irrelevant. No one ever denied that it’s best to act as you suggest: Heat pump, underfloor heating, and photovoltaic on the roof plus buffer battery. Ideal, great, I would do it that way too. Undisputed. Any deviation from this ideal configuration can only perform worse in terms of consumption. Right, yes right. Electric heating without photovoltaic? Pointless. Electric heating without sufficiently large photovoltaic? Pointless. Electric heating without a buffer? Actually also pointless. Roof area unfavorable. Pointless. Orientation unfavorable? Pointless. Powder sufficiently available? Pointless. Only a small niche remains where it actually makes sense. But there is one. And those are not necessarily idiots. I know the reality out there. You don’t. Infrared heater users, all idiots. Electric underfloor heating? Complete idiots. Window heaters anyway. No heat pump? Illegal. Wood chip heating? Probably just as crazy as gas with solar ten years ago. But these systems have been built thousands of times like that. You think they’re all nuts. That’s how you come across. And I stick to it: if I can have a large photovoltaic system installed for the same initial investment, then I would do that. Insulate the house well and then generate electricity in sufficient amounts. Even without a heat pump. But that’s what I would do. Who cares?!
