How would I properly size an indirect h20 htr for the following:
1 - double head shower (standard heads)
1 - 5' standard tub
1 - standard shower head
1 - clothes washer
5 - wash basins

I would be using a GB142-60 for the heating system.

Thanks!

    Indirect

    The twin shower head looks like your largest load. 5gpm water draw . The boiler is a beast ,did you do a heat loss calulation ?Any way if you take a 10 min shower at 5gpm you need a 50 gallon storage which would also fill the tub. The 60 would recharge the tank in 15min or less.
