    Hi all.

    We intend to put a stove (just room heating) into our house. I intend to place the stove on a hearth with flue at the rear of the stove, pass this through a hole in the wall and up the size of the house.

    I dont want the flue to be visible on the outside of the house, so we are planning to build a chimney on the outside of the house to effectively hide the flue so...........

    1. is this as striaghtforward as it sounds?
    2. if the flue is 6" then what do the dimensions of the chimney need to be?
    3. Would it work that the flue would pass out through the wall and then rise immediately at a 90 degree bend?
    4. the house has HRV so is the stove with external air supply going to work ok

    Any replies appreciated

    These questions should be discussed in detail with your Designer / Certifier. Will this chimney require planning permission?

    Yes, its as straightforward as it sounds. I've done it a few times.

    Standard chimney dimensions. The chimney must support itself. I can not discuss "structural" elements.

    It might work but the draw may not be great. IMO Better if you incorporate a 45 degree bend.

    A stove with its own air supply, fixed via duct directly to the stove should be fine with HRV.

    thanks for replies

    We have the foundations in for a standard size chimney. Is it correct that the pipes for the chimney will have to be put in as it is being built?

    If that is correct, is this again a standard setup or it is specific to the stove? (which has a 6" duct)

    I appreciate the advice on this topic already given.

    In order to correctly build this will I need to pinpoint the exact position of the wall opening before starting construction of the chimney?

    Is there only one pipe the stove flue (which is 6") or is this inside of another pipe?

    If the latter what is this outer pipe called?

    Any help greatly appreciated

    It realy depends on what you want.
    There are insulated flue pipes and single layer flue pipes. Different pipes for different purposes. If a stove with independant air supply is planned then an air supply pipe will be necessary as well. This could be placed in the chimney, paralel with the smoke flue.
    Check the actual demand with your stove installer, architect, civil engineer, energy advisor, builder ect...
