Sole heat pump flat collector 2 heating circuits

What kind of invoice is this? By the way, I find the price suspiciously cheap - what kind of modules are these? Cheap Chinese stuff? I pay almost 10,000 euros (minus VAT) for LG modules and 6.5 kW, and that is a "good" price. Especially since the company has existed for 15 years, so it has already gone through and survived all the downturns of the solar industry ;)

By the way, the feed-in tariff remains the same from the day of installation and does not decrease. And in summer, you can still produce hot water, which is needed consistently throughout the year. Additionally, you can "smartly" control various electrical devices and achieve maximum self-consumption.

Our system will have paid for itself after 11 years using a very conservative calculation, and then it will run almost the same amount of time again - tax benefits are not even included here, so it goes even faster. Additionally, the monthly cost burden is lower - even with a financed photovoltaic system (which you should do for tax reasons).

And connecting radiators to a heat pump is pretty much the most inefficient thing ever - it doesn’t work. Even with low-temperature radiators...

Oh, batteries: 2-3 more years, then more will happen - especially in terms of price. Right now, despite subsidies, it is just an expensive gimmick...

So guys, I have something positive to report. Our house is now getting underfloor heating completely both upstairs and downstairs. Your arguments were really good. It was not to be expected otherwise since everything else would not be efficient.
