Classic Hydronics Seminar

In this all-technical three-hour seminar, Dan Holohan will give you a Liberal Arts education in those Classic Hydronics 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
• Pumping
• Radiation
• One-pipe loops
• One-pipe primary-secondary systems
• Diverter tees
• Two-pipe direct- and reverse-return
• Two-pipe primary-secondary
• Multiple boiler systems
• Two-temperature systems
• Air problems and their solutions (once and for all)
• Classic radiant

And more!
