We need some info

John Barba had a nice webinar on sizing an indirect.



I suggest you view it.

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.
