Not so

Not every situation can be fitted with a condensing boiler due to nuiscance
pluming (flats, etc) - so a choice will still be available (B rated).

When I fitted my Keston, I was quite looking forward to seeing
a nice large plume. It was not to be -- the plume it emits is
pretty much exactly the same size as my neighbour's non-condensing
and my parent's non-condensing boilers.
