including modulating blower, negative regulated
gas valve/venturi, burner, temperature sensors
and more. Review the cleaning and service of the
three typical types of heat exchangers as well as
startup and combustion adjustments for reliable
Boiler Piping for High Efficiency
11:00am - 12:00pm, Cocoa 3
Bob “Hot Rod” Rohr, Caleffi Hydronic Solutions
This session explores the nuts to bolts
overview of piping strategies used for
today’s boilers. Some topics covered:
Managing boiler return temperature,
Zoning with pumps vs. zoning with
valves, Why Primary/Secondary?, Mod-
Con considerations, Buffer tank requirements.
Evaluating Existing Duct Systems
11:00am - 12:00pm, Cocoa 1
Ralph Adams, Parker Fuel Co.
How many times have you walked into
a home and the homeowner starts
talking about the A/C system they
currently own? Today’s high efficiency
equipment is not as forgiving as the
old. We will discuss how to evaluate
an existing duct system by measuring
the Total External Static Pressure (TESP) and
comparing them to the manufacturers specifications.
Outstanding Hydronics: Three Ways to
Add Efficiency, Performance, and Comfort
to any Hydronic System
11:00am - 12:00pm, Cocoa 4
Dave Holdorf, Taco
This program will explore how
customers can easily gain efficiency,
comfort, or performance or all three
to an existing hydronic and DHW
heating system using controls,
components and/or circulators.
Outdoor responsive controls will be
explored as a boiler reset, as well as load reset,
in order to gain system reset.
