Electric Heat Pumps for Domestic Space and Water Heating: Applications and Considerations

October 19, 2017 @ 9:00 am - 5:00 pm

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.

After attending the training, Attendees will:

  • be able to identify the benefits of ducted and un-ducted space heating heat pump systems
  • be able to identify the benefits of unitary and split water heating heat pump systems
  • be able to describe the potential benefits of HVAC driven filtration and indoor air quality
  • be introduced to performance parameters for proper installation of space and water heating heat pumps.
  • will review the current available refrigerants and discuss the climate impacts from the release of these chemicals into the atmosphere.
  • will review procedures necessary to ensure that the systems they install or specify are not leaking refrigerant.
  • will look at energy savings comparisons among existing equipment types to that they can look at total annual energy consumption for the equipment they are considering.
