Dan Holohan to Present Classic
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.”
