Any combis that can use a lined chimney as a flue?
I asked something similar a couple of weeks ago and have followed-up on
various sites but so far drawn a blank. Does anyone know of a Combi that could be fitted in a ground floor cupboard next to a 2 storey chimney breast with the flue going up the chimney breast? There is currently a Baxi back boiler fitted. How would the flue liner be installed? there's no access to the first floor flat. Dave |

Dave Combis have sealed (to room) combustion chambers, so need to *ingest* clean, oxygenated air as well as *expell* burned, de-oxygenated gases through the same flue. As a result, the flues are double walled, creating separate conduits for clean and burned air. Do you see where this is leading? ;-) hth Nigel |

Combis normally have lots of different flue fittings. So does the proposed combi have the appropriate fittings and does it allow a sufficiently long vertical flue. *read the manual* which may be on line. -- Dave Fawthrop dave hyphenologist co uk 17,000 free e-books at Project Gutenberg! http://www.gutenberg.net For Yorkshire Dialect go to www.hyphenologist.co.uk/songs/ |

I assume that some combis are spec'd to work with a long balanced flue but I haven't been able to find one by poking around on the web. I was hoping that someone on here might be able to point me at a suitable boiler and explain HTH I might get the flue into the chimney. Dave |

Keston now do a combi that needs 2 x 50mm muPVC pipes for air inlet and flue. According to the instructions you can run them up a disused chimney but how easy that would be to do in practice is another matter. http://www.keston.co.uk/C36.html -- Tony Bryer SDA UK 'Software to build on' http://www.sda.co.uk Free SEDBUK boiler database browser http://www.sda.co.uk/qsedbuk.htm [Latest version QSEDBUK 1.12 released 8 Dec 2005] |

I read your OP to mean that you wondered if you could just use the chimney as a surrogate flue. ;-) Best of luck Nigel |
