Default Condensing boilers and pluming

Hi

I've just had installed a Worcester Bosch condensing boiler system (R29 HE).

I understand that the pluming is common (inevitable?) with condensing
boilers. There is a fair amount of pluming with the R29 HE. I've been told
by a WB engineer that this will always occur (it'll be worse the colder it
is) and indicates that the boiler is working well.

The flue cannot be moved. Is there a way a way of lessening the visual
(cosmetic) aspect of the pluming so that it doesn't look like a smoking
chimney? I'm not suggesting that the emissions are lessened. I'm thinking,
for example, of putting something around the flue.

I understand that the emissions are more benign that conventional boilers
(although, ironically, the pluming makes them seem otherwise). However, what
sort of damage can the emissions do to a brick wall, double glazing,
anything else?

TIA

None whatsoever going by the total lack of any effect around the one
used here for the last 12 years.

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.

Yes condensate is slightly acidic, about the same as cola

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"

Not high enough to reach the roof and will be ugly outside the house.

vertical flue system upto a height of 15 meters is available"


These are two tube setups. Once again very ugly on the outsiude of a house.

None of these are plastic. The Keston is the best for long plastic runs.

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.

Not likely to make any difference. The flue gasses from condensing
boilers are much cooler than those emitted from conventional boilers. As
a result you tend to see the moisture content of the exhaust gas because
it will condense on contact with outside air.

I understand that the emissions are more benign that conventional boilers
(although, ironically, the pluming makes them seem otherwise). However, what
sort of damage can the emissions do to a brick wall, double glazing,
anything else?


So long as the flue has been installed correctly (should be tilted up
very slightly) then there is no risk of damage. A horizontal or downward
pointing flue could drip condensate which is slightly acidic however

Having previous had an Ideal Icos flued through the wall, I decided to put
by new Greenstar flue through the roof. A smoking chimney effect isn't so
disturbing up there!

Don't do this. A poorly designed flue shroud could cause the boiler to
dangerously malfunction. The main way to reduce plume nuisance are to run a
long flue, so most of the water is expelled already, or to run it to where
it isn't a nuisance, like shoving a vertical terminal out the top of a
unused chimney pot.

Thanks everyone for the advice.

The boiler is in the kitchen of a ground floor flat. There is no chance of
running the flue to the roof. There is no loft to move it too either. It
looks like I (and the neighbours) will have to put up with it.

It's a shame WB don't also provide a flue shroud (or something else) to help
lessen the effect of the plume. Lots of people have been staring at the
plume - and, judging by their expressions, I think the thing going through
their minds is "I'm not buying one of those boilers!". It is a PR disaster
but I guess over time people will get used to it.

Na - in time it will become a status thing ;-) You can see it now -
people offering a steam injection kit for boiler flues so that you too
can look like you have a condensing boiler....
