I suppose if non-condensing boilers go off of the market altogether
and CORGI fitters are forced to fit condensing models and there are
cases where the plume (if any) is a problem, then there could be an
issue.


How big can this plume be?

I live on the upper ground floor of a 4 storey town house, the boiler is on
the side wall where all the soil pipes are. Can this vent be ducted up the
side of the, there are is another building next door.

I am keen to get something that is energy efficent, but need something that
will fit into the 'tiny' space I have
