Looks like that heat exchanger is a desuperheater or a radiant floor / driveway melting size. Conservative rating is a half ton of water cooling as an evaporator, about 3/4 ton of heating as a water cooled condenser or desuperheater, and about 10 tons of water heating capacity being fed 180 degF boiler water.
