Electric Heat Pumps for Domestic Space and Water Heating

October 13, 2020 @ 9:00 am - 4:30 pm

The class will provide an overview of electric heat pumps for space heating and water heating.

As our electricity supply becomes cleaner due to increased use of renewable’s for generation, electricity becomes an attractive fuel source to designers and builders interested in reducing residential greenhouse gas emissions and creating zero net energy buildings. This all-day class will focus 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.

The class will provide an overview of electric heat pumps for space heating including both ducted and ductless systems. The space heating discussion will touch on interactions with indoor air quality issues, and building enclosure considerations. Heat pumps for water heating will also be covered. Interactions with other water heating strategies such as solar thermal and recirculation systems will be considered.

Learning Objectives

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