Well that sounds like a reasonable burner arrangement too. I was under
the
impression that some boilers used the burner underneath method, where,
in a
condenser, it gets a nice shower of acid.


I think if there were an award for worst boiler ever it would have to be
the Poxi- Batterton Barcelona condensing boiler. This would probably get
awards in both the design and reliability classes.

I think you mean the Potterton, I think Excel? Useless. the Barcelona was
made by Baxi and is now the Baxi something else. It wasn't bad at all.

Needless to say among the many a varied design flaws in the boiler is the
updraft premix burner.

I have to agree. Yet mine works well, gives no trouble and condensate does
not lodge on the burner corroding it.
