Webinar – Electric Heat Pumps for Water Heating
September 21, 2023 @ 9:00 am - 12:00 pm
As our electricity supply becomes cleaner due to an increased use of renewables for generation, along with a growing number of local ordinances prohibiting gas installs in new homes, electricity becomes an attractive fuel source to designers and builders interested in reducing residential greenhouse gas emissions and creating zero carbon homes.
Dan Perunko of Balance Point Home Performance will present on efficiency gains, and overcoming common installation pitfalls from electric heat pump water heaters in new and existing buildings. Class discussion will cover the advantages and limitations of these systems, the available technology and refrigerant types, as well as features like load flexing.
Agenda:
- Introduction and safety message
- Heat pumps water heaters (HPHW) overview
- HPWH lab performance data
- HPWH and solar thermal systems
- HPWH and space heating systems
- HPWH with CO2 as a refrigerant
- HPWH demand response strategy and efficiency
- Importance of efficient plumbing distribution system
The objective of this course is that at the conclusion, participants will be able to:
- Summarize the performance parameters of electric heat pump water heaters
- Discuss the relationship between heat pump water heaters, solar thermal systems and space heating systems
- Name at least two factors that have interactive efficiency gains of a plumbing distribution system
- List the impact of refrigerants and ways to guard against refrigerant leaks
- Explain the importance of a demand response strategy and its relationship to efficiency
