    Hello folks,

    I a refurbishing an old bungalow and will be putting in a solid fuel stove. A new floor is going in and I want to pipe in an air supply.
    How exactly is this done? What kind of pipe? size? where exactly does it enter to the stove?
    All help appreciated.

    Thanks,

    Eamon

    Well Eamon,
    First of all, you need to ensure your stove is external air ready. After that, generally speaking, you'll run a 4" sewer pipe under the floor and have it come up behind the stove, then mate it to a flexible stainless steel bend and attach that to the stove with a jubilee clip. Alteratively, if your stove backs on to an external wall, you can just run pipe straight out through the wall. Either way, wherever your pipe terminates externally make sure that water can't find its way in, and if you go underground, that all joints in piping are watertight.

    If you have a house with high air-tightness, you _need_ a stove with an external air supply. Otherwise you're dependent on the MHRV (or whatever air supply is being used for the house) meeting the needs of the house and the stove, and that's not practical.
    If your house isn't highly air-tight and/or doesn't have mechanically supplied air, then a normal stove should be fine - as long as you the proper ventilation in the walls, etc.

    so if my part L suggests I go with mhrv and a good airtightness value then I should really have an external 4inch pipe for air to underneath my stove? how does the stove then connect to the 4inch sewer pipe? tightly without having air escaping the envelope of the building I suppose

    I answered the connectivity question above, so re-posting here.
