Hello everyone!
In our single-family house from 1999, we currently have a Junkers gas boiler (Cerapur ZSBR) – some of them we have already replaced over the years, but overall we have always been quite satisfied.
During the last maintenance including power cleaning (with a high-pressure cleaner), the heating technician said that the values were not okay. He suspected that the exhaust system was drawing in air – where exactly, he did not know, and ideally everything from the boiler to the chimney on the roof would need to be replaced.
I then called our chimney sweep for a second opinion. He said that the values were not optimal but still within the tolerance range. However, he knew our boiler very well: he had the same one, even 1 or 2 years younger, and urgently recommended that we replace it immediately. He had disposed of his own last year. You can’t properly clean them, and something could develop into a safety risk – Junkers had a design flaw here.
OK, the system is 18 years old, but a complete replacement was not really on our radar yet. So, we got some offers from companies... but our question marks grew even bigger. Maybe one of you can contribute something to at least remove the plank from our forehead a little ;-)
1) The connections, Airfix, pipes, etc. are by far not installed according to current standards (if interested, I can gladly provide 1-2 photos). Not everything necessarily needs to be replaced, but most recommended it. Greed or sensible? As laymen, we cannot tell...
2) All offers were between 6 and 7.5 thousand euros. Boilers offered were from Junkers (Ceraupur ZBS 14/100 S-3 MA 21 or ZSB 24-5 C23) as well as Viessmann (Vitodens 200-W). Here, too, it is hard for a layman to recognize what is ultimately better. It used to be said that Viessmann is "the Mercedes" of boilers. Is that still the case today? They still seem to be test winners...
3) Only one installer spoke at all about the hydraulic balancing. He recommended it, but it would be almost 1 thousand euros extra. Is that really worth it in our case? The house has 125m2 of living space, 2 floors, and 10 radiators...
I would be happy if you could contribute something – I am currently overwhelmed. Keep running? Replace? If replacing, everything or just the boiler? With or without hydraulic balancing?
Many thanks in advance and best regards,
Matze
