the best draft inducer is a properly constructed chimney. Your chimney probably isn't high enough which makes a significant difference in the draft you experience. Fix the chimney and you won't need to play with any electricity-wasting draft-helping devices again. Fix your chimney so that it produces proper draft and plumb both boilers together in the same flue; preferably the coal boiler entering higher in the flue than the oil boiler. No need at all to switch pipes, screw around, or connect or disconnect your oil burner from the chimney, fix the draft problem with your chimney and you won't have to play around with this nonsense.

Quoted from an older post that is linked above.

daluds wrote: The chimney is roughly 26 feet tall going from basement to top of first floor roof of a cathedral ceiling family room right above the boiler room or basement. The family room above the boiler room has a 16x24 foundation off the main house. The chimney is capped for rain, etc. The chimney is lower than the top of the 2nd floor roof by about 12 feet.


I think the chimney being 12' lower than a nearby structure is contributing to the draft problems.

mark is spot on, 12' shorter than any part of the house? TOO short. fix your problems the right way, extend your stack.
