Webinar – Electric Heat Pumps for Space Heating and Cooling

September 14, 2023 @ 9:00 am - 1:00 pm

As our electricity supply becomes cleaner due to increased use of renewable’s for generation along with a growing number of local ordinances prohibiting installs in new homes, electricity becomes an attractive fuel source to designers and builders interested in reducing residential greenhouse gas emissions and creating zero net energy buildings. Dan Perunko of Balance Point Home Performance will present on efficiency gains and emissions reductions from electric heat pumps in new and existing buildings and will cover the advantages and limitations of these systems, the available technology and refrigerant types. Discussion will touch on interactions with indoor air quality issues and building enclosure considerations.


  • Introduction and safety announcement
  • Heat pumps for space heating
  • Case studies of zero net energy (ZNE) homes
  • Energy consumption of heating and cooling
  • Ducted vs. ductless heat pump systems
  • Indoor air quality (IAQ)
  • Refrigerant leaks and global warming potential
  • Performance of variable refrigerant flow (VRF) systems
  • Duct design and variable air flow systems
  • Electric resistance auxiliary heating in heat pumps
  • Q&A and course evaluation

The objective of this course is that at the conclusion, participants will be able to:

  • Identify the benefits of ducted and ductless space heating heat pump systems
  • Describe the potential benefits of HVAC-driven filtration and indoor air quality
  • Summarize the performance parameters for proper installation of electric heat pumps
  • Describe climate impacts from the release of refrigerants into the atmosphere and the procedures to ensure that systems don’t leak
  • Interpret energy savings comparisons among existing equipment types in order to determine the total annual energy consumption for the equipment under consideration
