Watching the news last night the reports on the current cold affecting much of
the USA showed several people demonstrating the extreme cold by throwing
boiling water into air just to see it transformed into ice crystals
immediately. I can see that in those circumstances a condensing boiler might
have a few problems. I have seen icicles form on wire flue guards but never on
the flue exit itself. Are we going to regret having condensing boilers when
the next ice age comes?

I expect we'll be regretting a lot of things when the next ice age
comes - or, more accurately, when the present inter-glacial ends.

Inter-glacials end quite suddenly too, although we're probably not
quite at the peak yet. The Arctic vanished completely in the last
inter-glacial (broke up and the fragments floated south as they
melted). We're not quite there yet.
