I'm looking to replace my old central heating boiler with a standard (i.e.
not combi) condensing boiler. I will have it installed by a professional,
but want to be more informed about available boilers rather than just accept
what the heating engineer offers.
I have heard that the heat exchanger (HE) on condensing boilers can have a
limited life, that cast iron HEs are to be avoided, aluminium are ok (ish)
and that stainless steel HEs are best. Anyone have any views?
I've also heard that Potterton are unreliable (for condensing boilers) even
though my old (non condensing) Potterton has served me well for nearly 35
Any other points tpo watch out for?
Does anyone have any recommendations (or otherwise) on makes/models of
