Commercial water heating systems are capital intensive and have long-term effects on building performance and occupant satisfaction. If sized incorrectly, it can lead to problems like energy inefficiency, higher utility bills, or lack of adequate hot water. The goal with sizing is to provide the required volume of hot water daily in an efficient, cost-friendly, and safe manner. However, sizing has become more challenging with the popularity of heat pump water heaters. Set to replace gas-powered water heaters, the recency of this technology along with its complicated sizing methodology with needs for tank-style setups has led to a host of challenges for specifiers who end up creating grossly ineffective and space hogging systems.This webinar explores how to size HPWH systems, discussing common mistakes, assumptions and limitations that frequently cause oversizing or under-sizing. We will also discuss the impact of varying hot water loads, demand responses, and ambient and groundwater temperatures on the sizing of HPWHs.
We encourage you to sign up for this webinar to discover a better approach to sizing hot water systems – particularly heat pump water heaters.
Learning Objectives:
- Describe why it is “tricky” to design heat pump water heaters correctly for a given application.
- Discuss common mistakes, assumptions, and limitations that cause over-sizing or under-sizing.
- Explain the impact of lower outdoor temperatures, ground water temperature, hot water loads, and demand response on sizing.
- Overcome these roadblocks and produce high-confidence heat pump water heating systems.
- Identify how to size large multifamily applications using the smallest footprint and lowest power needs.
