    @mattmia2 It is a gravity conversion yes. The original pipes are pretty big, maybe 3 inch or 4 inch pipe, not sure. Of note, there is a circulator delay built into the hydrostat and I do use that. The circulator delay keeps the circ from coming on until the boiler is up to at least 125, then the circ starts. If the water temp falls below 115 it will initiate circ. delay again.

    that seems pretty low to prevent condensing and it probably shuts off almost immediately after it starts. there is a lot of mass in that system and you usually try to keep the return temp above 130f to prevent condensing.
