Classic Hydronics (Dan Holohan)

Date: June 19, 2014

Time: 5:30pm - 8:45pm



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 explore:

  • 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 
  • Classic radiant 

And more! 

This seminar will be at Riccardo’s By The Bridge. We’ll begin at 5 PM with a delicious Italian buffet. Dan will start the seminar at 5:30 and will finish at 8:45. The Lovely Marianne will there with her bookstore and some great discounts for you. Come hungry for good food and knowledge.

Oh, and we have room for just 75 people and this one always sells out. As they say in Astoria, Ya snooze, ya lose.

See you then!
