Plug-In Heat Pump Water Heaters: An Early Look to 120 Volt Products
Amruta Khanolkar of the New Buildings Institute will give an overview of the emerging, retrofit ready 120V heat pump water heaters (HPWH) and findings from the California statewide field validation effort. This course will present the retrofit market opportunities and limitations with this emerging 120V HPWH technology. This class is for program managers, engineers, policy makers, installers, and California building jurisdictions. The objective of this course is that at the conclusion, participants will be able to:
- Learn about the plug-in HPWHs that are targeted for existing power and space constraint market
- Gain familiarity about emerging retrofit ready, plug-in 120V HPWHs (4 manufacturer products) and how they can be a silver bullet for the retrofit market sector decarbonization (national opportunities).
- Recognize the opportunity of the emerging technology for the California market sector, learn from the cold climate performance modeling results for Midwest
- Learn from the statewide California field study findings about the installation opportunities/gaps, customer/installer feedback and energy and performance of the technology
- Summarize lessons learned from current 120V HPWH field study projects and adopt key findings into for national demand building
Heat Pump Water Heaters in Small Spaces Lab Testing: The Amazing Shrinking Room
The Northwest Energy Efficiency Alliance (NEEA) contracted with Larson Energy Research and Cascade Engineering Services, Inc. to conduct a laboratory assessment of space requirements and venting strategies for standard unitary heat pump water heaters (HPWH). The laboratory testing provides detailed information about known but previously unquantified challenges for HPWH efficiency in enclosed rooms. Interpretation and application of the findings can help increase the number of cases in which a HPWH retrofit installation can be recommended and successfully implemented. Geoff Wickes of NEEA intends to provide actionable guidance and inform manufacturers, building designers, engineers, installers, and owners on various installation strategies and their impacts. The objective of this course is that at the conclusion, participants will be able to:
- Define three or more heat pump water heater terms (Uniform Energy Factor Performance, Net Free Area, Ducting Strategies)
- Summarize how the volume of the installation room affects heat pump water heater efficiency
- Discuss how effective different interventions are at improving heat pump water heater efficiency
- Outline the recommendations from the Amazing Shrinking Room research for future heat pump water heater installations
