Watching the news last night the reports on the current cold affecting

by throwing boiling water into air just to see it transformed into ice

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?

If it's condensing properly there will be little water vapour escaping
through the flue.


But the plume will still be very visible on a cold day.
