Do you have any customers who wait a long time to get hot water somewhere in their house? Do you know someone who is frustrated watching the water run down the drain while waiting when outdoor watering is restricted due to drought? Have you ever wondered why a shower sometimes feels wimpy and what you can do about it without adding a boost pump? And, given the trend toward decarbonization, how do you pick a water heater that will provide customer satisfaction and be energy efficient? Would you like to know how to solve these and related problems in existing buildings and prevent them in new ones? We will discuss the answers to these and other questions during this fast-paced class.

Learning Objectives

After attending this class, participants will be able to:

• Identify the causes underlying occupants’ number one hot water complaint (it takes too long for hot water to get from a water heater to fixtures) and what can be done to fix the problem in existing homes and prevent it in new ones.
• Describe the value of the IAPMO Water Demand Calculator to right-size the plumbing in single-family and multifamily dwellings.
• Assist homeowners in selecting replacement water heaters that will meet their household needs as well as State climate goals.
• Summarize the variables that need to be evaluated when replacing an existing non-heat pump water heater with a heat pump model.
