Can you recommend the best choice for:
3 gas hot water boilers + 3: 40 gal. dhw indirects

Heat loss btu's:
basement: 20,400 / 1st floor: 26,500 / 2nd floor: 34,400

Considering three Slant Fin SE 70's with WeilMcLain 40 gal. indirects.
The hot water consumption is not much, so the derating of the indirect's performance with the small boilers seems OK.
The boilers must have MEA numbers.
