The Art and Science of Domestic Hot Water Design (1 PDH)

Date: June 20, 2025

Time: 12 pm – 1 pm

Location: Virtual

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.

Who should attend:  Plumbing & HVAC design engineers
