    Incredibly noisy boiler from flue.

    I've just had a Worcester Bosh 25-32 Heat Slave oil fired boiler installed and the sound from the flue is like a jet engine and can be heard 25 yards away at the bottom of my garden. I'm told oil fired boilers are quite noisy but this is ridiculous. Is this normal. I even spent a few pounds on a...

    Hi all, can anyone advise if it's possible to route a flue from a condensing boiler in an underground room up through the ceiling (15" thick) where it will come out above ground on a flat surface ? And from there it will extend up the side of the house, as in this picture ?

    I’m going to be moving a Vokera Unica i32 on Monday. I had a quick look at the building while driving past and it looks like the steel gas service pipe running externally to the flat above is where the flue would come out so I’ll have to re direct it a bit. I was looking at BS 5440 and can’t...

    Flue integrity test

    I always do a flue integrity check on the air inlet sample point. Never had an issue. Doing one today and I realised I don’t know what values the are to be classed as a fail. Can’t seem to find it in my books either. Is there a TB I can read to refresh my brain?
