flue pipes

If it is an older home there could be a draft regulater in the chimney itself below the flues, it could be on a different side than that which the flues enter.

    flue pipes

    my daughter is buying a home that has an oil fired boiler and oil fired hot water heater. Both vent into 1 chimney. The flue for the hot water heater is below the flue for the boiler. Is this correct? Also, I was told that both flues should have dampers. Neither flue does. Is this a safety issue or a performance issue?

    Good Questions

    Find A Professional ( this site) will be your best piece of mind. Working with oil heating many years the safty & performance issue is key in my mind. The draft in the chimney is important to that when I come to clean and inspect I always remove the flue and inspect the chimney.

    when finished the draft over fire and draft in flue pipe must be checked with test meter.

    More draft than needed, will suck your heating dollars up the chimney, not enough and flue products can enter the home and further cause sooting in the equipment also wasting dollars.

    Thanks for the question

    Dampers

    If you mean a damper to shut off the flow of exhaust gases, that is not required. In fact, those type of dampers tend to be disconnected in place because they don't seem to hold up well.

    If you mean a draft regulator, which is a barametric damper mounted on the side of the flue pipe for each unit, that may well be needed for both efficiency and reliability. A few manufacturers don't require them, but I think that is only for boilers.

    As far as which is on top, I don't think it makes any difference.

    Flues

    Typically you like to have the smaller flue over the larger flue and you enter the chimny even if both fuels are the same.

    Both pieces of equipment should have draft regulators (I am assuming they are both natural draft, since they are venting into an active chimny.

    Best to get a good oil company out the check and also have a chimny sweep go over the complete vent system.

    Also a service contract with annual maintenance is always a good idea.

    I agree with Mitch,

    Larger appliance under the lesser one. And so I call the dampers you are talking about, "Barometric Dampers" These are needed to adjust "over fire draft" It's been a while since I smelled like OIL, but I'm sure someone can point you in the proper direction. Everyone is great here and it's a community like no other. ;-)
