This measure is the addition of a ductless heat pump (DHP) to an existing home with a central electric forced air furnace (EFAF).  The DHP has a higher coefficient of performance (COP) than an EFAF and uses less electricity to provide the same amount of heat.  Typically, the DHP is used to offset some or most of the heating load otherwise met by the EFAF.  However, this measure specification does not include a control strategy, nor does it preclude homes with significant supplemental fuel use.

Heating zone three of the measure was deactivated in 2018.  As of 2021, new BPA evaluation data prompted a re-evaluation of heating zone 3. Following RTF review of the new data, heating zone 3 was adopted with a planning status due to large remaining uncertainties and small sample sizes.  The associated research strategy outlines two research objectives.  These research objectives could be completed through a billing analysis and site visit/survey or other methods that achieve the following objectives :

  1. Estimate the energy consumption change for single family and manufactured homes, separately, that install a ductless heat pump to augment/displace the usage of their pre-existing electric forced air furnace.
  2. Estimate the presence, usage (pre/post), and impact of air conditioning (AC) and supplemental fuels in the treatment and control groups along with any other related changes that would affect consumption in the post period relative to the pre-period.

The measure remains proven for heating zones 1 and 2.

Approve measure update with direction for future analysis.

Decision Details

Accept the research strategy for the Residential Existing MH and SF Ductless Heat Pumps for Electric Forced-Air UES measure, and set the measure Category to 'Planning', Status to 'Active' and sunset date to March 2016.

The 1-year sunset date is intended as a check-in on the research plan process, not a revisit of the measure workbook. Since the check-in process (with the R&E subcommittee) is new and still under development, the RTF was not comfortable with a longer sunset date.
