Replacement for existing expansion tank

Actually, there is this only to say that this expansion tank fits on the existing fortifications. So if Winkelmann was off before, fit this part. Of course, it is recommended to measure in advance and to obtain information on the manufacturer's website. Incidentally, "only" the nitrogen was the old conservator disappeared and thus the inlet pressure to zero bar, after over ten years of operation was not surprised - at a maintenance checking is often forgotten. With air inflated the expanded vessel kept the pressure of 1.5 bar. But that's debug during operation in winter is not ideal - and so expensive, the new part is not well. An installer would not have done it differently.
