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 Praful (Remove spam-spoiler "ABC" from email address) |

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 Nick |

A 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. |

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. |

Yup - sounds right so far. The flue cannot be moved.

I'm not suggesting that the emissions are lessened. I'm thinking, for example, of putting something around the flue. 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 -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

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? 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! I'm not suggesting that the emissions are lessened. I'm thinking, for example, of putting something around the flue. 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. Regards Praful (Remove spam-spoiler "ABC" from email address) "Christian McArdle" wrote in message et...
