in Strictly Steam
Anyone know if it is approved to twin 2 IN7 steamers together. Nothing in the iom manual and just wondering. It is to late to get a hold of Burnham today but am trying to figure out.  Small apt building without heat and only ones I can get quickly. Thanks all, Tim

    modular boilers

    here is a link to several discussions on the subject:

    with a vaporstat controlling the boilers, you could come up to operating pressure on the 2, and then switch one off and on to maintain the low pressure we like for steam. the manual for my peerless 211a shows a modular installation piping diagram, so it would give you an idea of how it can be done.--nbc

    Re: Twinning

    Gerry and Nicholas, thanks for the replies. My main question was that I did not see it in the Burnham pipe up and was just seeing if there was any reason not to do with the Independance boiler. I looked at the Caravan boiler from slant fin also but the Burnham I can get faster and in turn get heat back to these 13 apts quicker. The pipe up is pretty straight forward but just wondering. Thanks again, Tim

    tag-team boilers

    how has the old boiler failed? it's useful to know that, if possible, to make corrections on the new installation.

    are you sure about the size of the new boiler you will need [edr]?

    the modular aspect does look to have long term advantages in fuel economy, when used with a vaporstat, as long as the piping/pressure is right. you don't want the inactive boiler to have a wild rising waterline as the active continues to fire at too much pressure. my 7 very large apartments heat well at 8 oz. max. i have very generous main [not radiator] vents. let us know how it comes out, with fuel use information if possible. the gas company may think the meter is malfunctioning, , due to the lower consumption,and change it out, as they did in our case!--nbc
