In this all-technical three-hour-and-ten-minute seminar, Dan Holohan will give you an education in those Classic Hydronic heating systems. He'll have you seeing inside the pipes as he gives you a better understanding of how things work, what goes wrong with them, and why. He'll share with you the secrets he's picked up from the Old-Timers and he'll make you a better troubleshooter.

We'll look closely at:
The critical importance of pressure differential
Gravity hot water heating systems
Pumping in heating systems
Radiation
One-pipe loops
One-pipe primary-secondary heating systems
Diverter tees
Two-pipe direct- and reverse-return
Two-pipe primary-secondary heating systems
Multiple boiler heating systems
Two-temperature systems
Air problems and their solutions (once and for all)
Classic radiant heating systems
And more!
