    We need some info

    John Barba had a nice webinar on sizing an indirect.



    I suggest you view it.



    For the formula to find out how many gallons of water your going to use go to hot water.com



    If you want tankless then see me

    I would be cautious about adding any BTUH's to the steam boiler. You'd be surprised at just how effective an indirect tank will be, even at lower input BTUH's.



    At 14 showers, I would look for a First Hour Rating of 240. If your total BTUH's are close to 200K, you'll be fine not adding any extra.
