Slant/Fin held its Hydronic Heating Expo in November 2003, drawing a crowd of more than 300 heating contractors, fuel oil dealers and industry professionals at the LaGuardia Marriott in New York City. Joe Coppola, boiler marketing manager (pictured), performed combustion tests on a live-fired Slant/Fin XL-2000 oil boiler for expo visitors. The expo included equipment displays, technical seminars and product demonstrations. Dan Holohan, a columnist for Supply House Times, gave an address on steam heating.
