Direct Vent Oil Fired Steam Boiler

BoroughPete Member Posts: 2

Hey All! I am new to the forum and brand new to steam heating.

I am purchasing an 1800's home in Connecticut with a whole suite of beautiful single pipe steam radiators. Unfortunately the combi boiler is shot and the inside of the fireplace has partially collapsed. Probably due to the back pressure of the fireplace being blocked, the steel exhaust ducting split and the boiler is exhausting right into the basement! While the steam had been shut off the combi boiler is still operational for hot water. Not cool.

I am hoping to replace the boiler with an oil fired, direct vent steam boiler but my searches have not turned anything up. Does this exist? Everything I have found is chimney vented. From what I have read here power vents are highly undesirable.

My ultimate goal is to restore the chimney to use for burning wood, but with my budget that might be a couple of years out (The fireplaces have been closed up with brick/plaster).

Thank you all in advance!

    Combi boilers are for hot water. Are you sure this is a steam system and not a converted gravity hot water job?

    Can you post some pictures??

    I am definitely not an expert on these things, but this thing makes steam and hot water…

    The tag hanging on the wall shows it is an old Burnham V35, 228MBH unit.

    You use the coil in the boiler for hot water .. I don't think they make a direct vent steam boiler . I am not sure if the Burnham Mega steam boiler can be setup direct vent . You may want to check it out ..

    A stainless power venter is another option … Check out Field ….

    There was an error rendering this rich post.

    What's the issue with having a stainless steel chimney liner installed in one of the existing flues?
