    We are looking to install two 250,000 btu boilers and two 110 gallon holding tanks to provide hot water to a 40 unit apartment building. What would be the best way to install them to get the most redundancy and efficiency? (each feed tank individually, then join them after the tanks, in sequence, etc?)
    Thanks.

    Are these mod/cons or cast iron boilers. Use indirect water heaters for the hot water. Whose tanks are you using?
    Piping will depend on boilers

    These are Lars copper core boilers. We were not planning on using tanks with a coil.

    What does it mean to stage fire the boilers?
    Thank you.

    They fire to demand. On low demand a single boiler fires, as demand increases the 2nd boiler cuts in. Re-set modulating controls would be a very good addition also.

    I would agree with Tom about stage firing. I would probably pipe them as reverse return to balance the flow between the tanks.
