Of the straw poll list. The number one avoidable problem would have been correct primary circuit layout to reduce air ingress. On the sealed systems it would have been maintaining primary pressure.
Hardly any of the boilers (that I took out) died due to poor maintenance as such.
In fact a significant cause of death was being inefficicent (2) or being conventional when they should have combi(>3).
You just change the pump head, which is standard and available in many local sheds. The Microgenus's pump head appears to be a standard Willo with the body having 2/4 cxns.
Many are just kits with third party components: Grundfos pumps, Honeywell
3-way valve, Honeywell, gas valve, etc.

Why, have all the old houses been flattened again or something?
A significant percentage of Germans live in flats. You're telling me that someone living in a ground floor flat has a flue rising up six storeys or something?
And the flues still go through the roof.
Yep! U or C ducts

Well having lived in more German houses than you, I can say that you are, without a shadow of a doubt, wrong.
They do have U and C ducts in Germany. These are common flues. What Stalag were you in?
