    If it's the usual setup

    where the Vaporstat breaks the circuit to drop the boiler to low fire, it will work fine.

    Ahh.

    I was just thinking about this concept the other day. Made a post about it. Figures, it already existed somewhere.

    Hmph.

    Well, at least I know it's a good idea. For whatever that's worth.
