hot water coil

Steve Hendriks

Can anyone tell me if they know of a tankless indirect fired hot water coil that can produce 40 USGPM. I have a spec on an Aerco model but I can't get my hands on it. I'm looking for an equal.

it's a big boiler...

I hope. You'll need 1,200,000 BTU/hr net at 60°F rise and 2,000,000 BTU/Hr at 100°F rise, say perhaps 10 to 20 GPH firing rate if #2 oil, plus whatever's needed for other loads on the boiler. Why not use a heat exchanger -- flat plate or shell & tube and a (large) boiler water circulator?
