NG fired steam boiler recommendation

in Strictly Steam
A friend needs to replace his existing steam boiler and while we unfortunately have no real steam pros in the area, I do know one greybeard plumber that has done enough steam and will actually follow a manual.  Homeowner has a copy of We Got Steam Heat (thanks, Dan) and I will be reviewing the proposed piping and sizing with him before he signs a contract.



A 3-pass with a gas conversion would be great, but the plumber is not familiar with them and I think that's probably asking too much at this point, so I'd like to recommend something that can be bought as a package.  What say the pros?



thanks~

    Installed EDR

    HI- What's the total EDR of the system?

    EDR

    Don't have that just yet, but I suspect based on the size of the building and the age that we're looking at something in the 300-500 sq ft range.

    I'm not a pro

    but Smith is delivering the G8 with a Carlin EZ Gas power burner as one of the factory supplied burner choices. It should be no problem as long as the installer has a combustion analyzer.



    Mine gets installed Monday.

    Smith G8

    Thanks - I'll look into that.



    I have a CA and will probably do the final setup.



    Edit: No mention of gas in the IOM - is there any documentation on this option?

    G8 and EZ Gas

    Smith does a great job of hiding this, let's see if I can get the pdf to attach to this msg. If not point your browser to - http://www.smithboiler.com/html/g8.asp

    G8 with EZ-Gas

    Thanks - that brought up the brochure but I still can't figure out how you actually got there - they really did hide it.



    I'll call Smith on Monday and see if they can provide model numbers and an IOM.



    If this proves too rich for his blood, what would the next best choice be?  Steamhead?



    thanks~

    Slant/Fin Intrepid

    with EZ-Gas would be my other choice.



    Give the customer a comparison of an atmospheric boiler's thermal efficiency against the G8 or Intrepid, and they'll likely go for it. Almost all of our customers do.

    G8 with EZ-Gas

    Spoke with Smith yesterday and they said they are no longer shipping the G8 package, which explains the lack of info on their site.  Need to order with the -LB option (less burner) and source the EZ-Gas separately.



    My Slant/Fin rep was utterly convinced that the Intrepid was no longer available.  Slant/Fin is calling to educate them now -- I know we don't do much oil out west, but sheesh...

    -

    just bought a smith 8 series less burner with carlin ez gas burner last week.  due for delivery this week.

    -ain't too hard to slap it on and maybe make an orifice change VS prepackaged.

    There was an error rendering this rich post.

    Efficiency comparison

    Anyone have numbers they can share with regard to this?  Nameplate ratings will certainly be helpful, but real-world fuel usage comparisons would rock.



    thanks!

    Smith. Carlin.

    I'm going to be installing a Smith/Carlin steam job tomorrow. I'll post my combustion numbers. I'm going to keep a log of every boiler I install this year.

    86.2% efficient. Going back on a colder day to make the final adjustments.
