Hello,
Sorry for the english, I'm french and don't speak any german.
The pressure of my central heating circuit (Vitodens 222-F BS2B) is suspiciously rising, I'm afraid there is probably a leak on the heat exchanger inside the water tank (Viessmann ref 7831727).
Is it possible to completely remove the water tank and use a plate heat exchanger instead ? (Viessmann 7828044)
Thank you
