what would be a good choice for boiler water capacity.
boiler needs to be around 108,000btu with a tankless coil
and be hooked to a heating and cooling coil for hot air system. the boiler the supply house is pushing is a thermo-dynamics 15gal other choice is new yorker fr-122 with 20gal and home owner asked for third choice with 25 gal capacity
i guess my question is with a hydro/hot air set up are you better off with higher or lower mass boiler-appreciate any
comments thank you mike........

boilers
I don't do hydro air set up but know one company that does that exclusively. They use a system 2000 boiler which is super LOW mass (2.5 gal).
Both the boilers you mentioned are steel w/ tankless htrs.The 15 gal. content is to help the tankless water to keep up w/ demand.
Is this a low budget job? the only other steel package I know of is a Burnham rsa.
If you could I would get them up to a seperate indirect instead of the tankless.With maybe a TDynam. LM series.
the boiler mass does not make that much of a difference w/ the hydro air set up in my opinion.0
