Or the system has been poorly installed.

This is, as usual, total crap from dribble.

My brother had a BF BE floorstander with cast iron heat exchanger replaced
by a condenser after BG said they couldn't maintain it anymore under their
service contract. 18% saving in gas costs - and take my word for it he
knows how to work these things out accurately.

The replacement breaks down at least twice a year. And is broken at this
moment leaving them with no heating or hot water for 4 days - really
useful in the NE of Scotland.

Of course if it stays broken this could well make the gas saving of 40%
that dribble says.
