A friend is buying a co-op with a Burnham Spacemaster SM3 boiler. I cant find much info online about them. What is your opinion of it? She is conecrned about costs to maintain and “tune ups” if needed.

  1. To tell you the truth, I can’t think of a single reason to use that boiler. Evidently, neither can Burnham. They are only distributing it for another manufacturer and don’t even bother to list it on their website.
    Where a sidewall-venting boiler is required, why not install a 92%-96% efficient unit instead of the 82.5% efficiency delivered by the Spacemaster. The venting requirements are the same and that’s always the biggest obstacle in a wall-mounted boiler.
