If you don't like the nuisance plume, then
the only alternative is to have the boilers
flue fitted through the roof, as they do in
Germany. Get the boiler moved to the loft.

Don't move the boiler to the loft. One of the advantages of condensing
boilers is that the exhaust gasses are not hot so you can use long
plastic flues meaning the boiler doesn't have to be sited on an
external
wall.

It depends on the boiler. The W-B is not one, it will have to be
moved.

According to the Worcester Bosch Installation manual available here
http://www.worcester-bosch.co.uk/framest7.htm

" The standard Concentric flue system provides for a horizontal length
of upto 4m.

Systems are available to give a maximum horizontal lenght of 13m. A
vertical flue system upto a height of 15 meters is available"

Concentric flue extensions are "very" expensive. The 28 HE cannot use
plastic drain piping for the flue. Putting the boiler in the loft solves
many problems and releases space in the kitchen.



Moving the installation, relocating pipework and all associated disruption
and redecoration cheaper than installing a tall concentric flue? Somehow
doubt it.
