SUMMARY:Electrification Made Practical (1 PDH)
DESCRIPTION:Date: February 27\, 2026 \nTime: 12 pm – 1 pm \nLocation: Virtual \nPDH: 1.0 PDH \nTrainer: Robert Barrett  \nThis presentation looks at how power is produced at the plant level\, the mix of fossil fuel and non-fossil fuel-based energy within our energy grid. “Point-of-Use” efficiency of electric appliances. The COP requirements of heat pumps are required to be at parity with condensing gas-fired units. Why “electrification” is a “green” technology\, even with the current fossil fuel mix\, the costs for fully electric systems versus conventional systems\, and why hybrid systems make sense ecologically and financially. \nWho should attend – HVAC & Plumbing engineers \n1.0-PDH            Duration:  1-hour                PS#202411038 \n  \n \n

SUMMARY:Controlling Condensing Boilers & Water Heaters (1 PDH)
DESCRIPTION:Date: April 24\, 2026 \nTime: 12 PM – 1 PM \nLocation: Virtual \nPDH: 1.0 PDH \nTrainer: Robert Barrett  \nThis 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. \nBoiler 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. \nTakeaway: \n\n Understand what causes a boiler to condense and how to optimize this\n Detailed review of condensing boiler efficiency curves as they relate to boiler LWT-reset and NYC weather data\nCompare the savings associated with boiler LWT reset versus the savings associated with constant LWT and variable speed pumping.\n Discover how to make every DHW application operate in condensing mode\nUnderstand the benefits of applying a front-end lo\n\nWho should attend: HVAC & Plumbing design engineers \n1.0-PDH            Duration: 1-hour                PS#20207027 \n  \n \n
