The seminar will begin at 5 p.m. with a buffet dinner. Holohan will begin speaking at 5:30 p.m. and he’ll finish up at 8:45 p.m.

“This all-technical seminar will give you a liberal arts education in classic hydronic systems,” said Holohan. “You will see inside the pipes and get a better understanding of how things work, what goes wrong, and why. I’ll share with you the secrets I’ve picked up from the old timers, making you a better troubleshooter.”

This class explores one-pipe loops, the critical importance of pressure differential, gravity hot-water heating, pumping, radiation, one- and two-pipe primary-secondary systems, two-pipe direct and reverse return, classic radiant, multiple boiler systems, diverter tees, two-temperature systems, air problems and their solutions, and more.
