The National Association of Oil Heating Service Managers 55th Annual Convention and Trade Show will take on green heating issues May 18-22, 2008, at the new Connecticut Convention Center in Hartford, Conn. PM columnist Ellen Rohr will show attendees ways that companies can build business by getting their customers interested in upgrading their equipment for greater efficiency. Radiant expert “Hot Rod” Rohr will share some of his personal experiences with the planning and installation of radiant systems, as well as showing attendees how to integrate solar - and other alternative fuels such as wood and biomass - into their systems. And PM columnist Dan Holohan will present “Greening Steam,” which will earn attendees two NORA CEUs.
