Steam heating expert Dan Holohan will donate proceeds of two back-to-back steam heat seminars to NAOHSM's Dave Nelson scholarship fund. He will present two separate admission seminars Aug. 27 and 28 at the Holiday Inn, King of Prussia, Pa. Holohan will forego speaker's fees, enabling net proceeds to be added to the endowment fund. Registration for both of these seminars is available on the NAOHSM Web site at
