    I am building a single story extension to the back of my 2 story terrace house. I am thinking of putting in a stove and connecting to my central heating system.
    My question is: does the chimney flue have to be higher then the two story part of the house or only a meter heighter then the highest part of the single story extension.
    The stove chinmey flue will be approximately 2.8 meters away from the neighbours boundary. Thanks

    I don't know how high it has to be but I do know that the higher it is the better the draft or draw will be through it - which is a good thing. Your installer should know, if he doesn't then I would get someone else.

    Once you have enough height to get a good draft then the reason for taking the stack up higher than the top of the nearest roof section is to stop the wind blowing over the roof and straight down the chimney. There are other issues but you can often get away with a shorter chimney however there may be times when the house will fill with smoke if the wind changes.

    You can often take a look at a roof and work out where the wind will be blowing. The further away from the highest part of the roof you go the less effect the roof will have so you just need to extend the chimney up into the area not affected by wind coming over the roof. For example if you put the new chimney at the furthest point away from the original roof you may not need to go as high as if you put the new chimney on the side of the old house nearest the original roof - hope that makes the slightest sense even if it all generalisations.

    Edit> to put some figures on that an imaginary line to the nearest part of the roof would want to be over 3m away then add 1m. There may be regulations that refer to less distance but I'd still try and get at least 60cm above the house gutter even if more than 3m away. + the obligatory don't take my word for it get professional advice.
