Dan Holohan to Present Classic HydronicsSubscribe to RSS feed

 Dan Holohan will present his popular seminar, Classic Hydronics, on Wednesday, April 9, 2014 at the Holiday Inn in Grantville, PA. All proceeds from this seminar will benefit OESP’s Dave Nelsen Scholarship program for students interested in pursuing their careers in the energy-service industry.


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


“This all-technical seminar will give you a Liberal Arts education in Classic Hydronic systems,” says 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.


In keeping with the compassionate spirit of our industry, OESP encourages all attendees to bring a non-perishable food item that will be donated to a local food bank.
