Efficiency & Turndown: Hype Vs. Fact About Gas Fired Water Heaters & Boilers

to take this course

Turndown has been a hot topic for a while now, but it isn’t a magic solution. Join us in this one-hour course as we separate the hype from the facts about high turndown, looking at real-world applications. Participants will learn why its better to focus on combustion and thermal efficiency to achieve high efficiency.

Learning Objectives: 
  1. Recognize the different definitions of turndown ratio and explain how turndown became a contentious topic in terms of efficiency and sizing
  2. Summarize system challenges to achieving very high turndown, focusing on short cycling and boiler efficiency
  3. Articulate the real-world advantages and disadvantages of a higher turndown boiler by reviewing a case study
  4. Contrast combustion efficiency and thermal efficiency and illustrate how the terms are connected and what factors impact them
  5. Develop new and existing designs that achieve high efficiency by utilizing cooler return water to maximize efficiency of a condensing heater
