    So going to a boiler would be an expensive thing to do.

    Didn't catch that
    I didnt see that but I did make an assumption that it could be one or the other.
    If it was a boiler I would go hydro when considering a new a/c unit to boot.

    Thanks for the catch

    No, a stage LP furnace isn't more efficient in the lower stages.

    And they do have 2 stage oil furnaces.

    How many times must one fix something before it is fixed?

    Very interesting and, to a layman, counterintuitive.

    One would think that operating at a lower stage would be more efficient in addition to possible comfort benefits.

    I must look into the multi stage oil furnaces. Got any favorites or recommendations? Thanks-

    In teh lower stage they provide more comfort.
    But, if the house needs 40,000 BTU's it need 40,000 BTUs weather in first or second stage. So it burns as much and some times more fuel in first stage.
    But makes the house feel much more comfortable.

    oil and heat pump..

    Never saw a furnance that the nozzle couldnt be changed here in oregon...
    Depending on electricity rates, the heat pump could be the best solution for 80% of your heating, with oil [ it never explodes like LP] for those below 20 nites with 40 MPH winds.....

    I reason per the tech guy I talked to is that a lower than the std 1 gal per hour nozzle will cause the combustion chamber to run too cool and form condensation that will eventually kill it. He was quite certain on this.

    Funny you should mention propane being explosive. Just saw in article in my local paper that this happened recently. Whether due to a leak or stupidity is not yet known.
