 Siegenthaler also will present a seminar April 2 at the Mohawk Valley Community College’s Utica Campus on using renewable energy sources such as solar thermal collectors, heat pumps and solid fuel (wood and pellet) boilers with hydronic heating systems. This full-day seminar will show students how to use each of these renewable heat sources as the primary energy source for space-heating and domestic hot water production.
