Wall hung boiler attached to brick chimney

Solid_Fuel_Man Member Posts: 2,646
I'm doing a bid on replacing a wall hung boiler which is attached to unistrut on a chimney. This chimney is only used as a chase for the polypropylene vent and intake pipe. 

I was just going to replace the boiler with one of my choice and reuse yhe 2" venting. But in talking to another contractor they said they looked at the same building and that it can't be accached to the chimney. 

Thanks in advance!

    I don't see a thing wrong with it.

    you could use a floor mounted boiler

    Or make a strut rack to mount the boiler on supported at the floor and ceiling

    We, as a matter of course, just specify a new built wall to mount the boiler. We build the wall with the boiler configured in the shop and transport the entire thing to the job site. Makes it simple. The wall is usually 2x4 framed with some mounting surface either drywall or something else prettier depending on how fancy we want to get. We have yet to find a homeowner nostalgic about their basement walls.

    I was considering using strut floor to ceiling. I actually have a wall hung boiler already....I bought several ECO70 and got a good deal on them before things got crazy expensive. 

    But I don't have to use it, would just male piping that much simpler.

    In a basement with floor joist above? hang a 1/2 sheet of plywood down to mount on. Some rubber grommets behind for some sound insulation.
