Controlling Condensing Boilers & Water Heaters (1 PDH)

PDH: 1.0 PDH
Trainer: Robert Barrett
This presentation looks at the efficiency curves of condensing boilers and compares these curves to NYC weather bin data to determine the efficiency of a condensing boiler over a heating season when it is designed for non-condensing design temperatures of 180F-160F.
Boiler outside air reset control savings are compared to pump VFD savings; control options are discussed. Also, water heater piping design is demonstrated to have a large impact on domestic hot water heater efficiency. Some Lochinvar products are discussed along the way.
Takeaway:

Understand what causes a boiler to condense and how to optimize this
Detailed review of condensing boiler efficiency curves as they relate to boiler LWT-reset and NYC weather data
Compare the savings associated with boiler LWT reset versus the savings associated with constant LWT and variable speed pumping.
Discover how to make every DHW application operate in condensing mode
Understand the benefits of applying a front-end lo

PDH: 1.0
Trainer: Robert Barrett
This presentation covers the fundamentals of heat transfer, dissecting each variable. It covers fixture accounting, occupancy assumptions, fixture schedules, DHW percentages and cold-water requirements, fixture units, diversity factors, and high level assumptions.
Take-away:

Learn to be comfortable with the basics of heat transfer as it relates to production of potable hot water
Discover a means of calculating domestic hot water loads that allows the engineer to record all of the assumptions and directly calculate the DHW demand (no more “black-box” methods).
Gain greater understanding in what goes into determining diversity factors, assumptions on occupancy and other human factor elements.
Compare ASHARAE sizing methods to fixture flow and usage methods of sizing DHW demand.
