We have a small solar thermal system on the roof. This was absolutely necessary because we have a gas heating system (heating station with storage is from Fa. Wolf). We finally wanted to know how effective our system actually is. At first, we thought we were just too dumb to find the values on the display. After a lot of back and forth with the heating company, it turned out that our system does not have a "Wärmemengenzähler". "The system only saves about 5% anyway. And besides, we only installed all this because the legislature requires it," was the statement. I'm baffled now... This is the first time I've heard that. We paid quite a bit for it but cannot verify at all what the system delivers? Is this common???
How is it with you? What do the solar collectors achieve? Can you read out your "Wärmeertrag"?
Best regards Steffi
