Controlling Condensing Boilers & Water Heaters (1 PDH)

Date: February 7, 2025

Time: 12 PM – 1 PM

Location: Virtual

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

Who should attend: HVAC & Plumbing design engineers
