The high efficiency HVAC rate is available to customers who:
  1. Use either an air-source or ground-source heat pump as their only source of heating and cooling in their home.
  2. Use an electric water heater (usually connected to the desuperheater of the heat pump) as their only source of domestic water heating.
  3. Receive prior approval of the equipment from RPU. Note that equipment must be rated by the American Refrigeration Institute (ARI)* and meet the minimum efficiency standards listed below:
Minimum Qualifications for Air Source Heat Pump:

SEER (1)
14.0

Minimum Qualifications for Ground Source Heat Pump (GSHP)/Geothermal Systems:


EER (2)
14.1

(1) SEER: Seasonal Energy Efficiency Ratio
(2) EER: Energy Efficiency Ratio

*For air source heat pumps and water-to-air ground sounce heat pumps: The efficiency ratings are determined using the Air Conditioing and Refrigeration Institutes (ARI) directory, which may be found at www.aridirectory.org. For water-to-water ground source heat pumps: The efficiency ratings are verified using manufacturer specifications, which clearly demonstrate the Entering Water Temperature (EWT), Gallon Per Minute (GPM) water flow, and associated EER rating.

These must be individual private dwellings where service is supplied at one point of delivery and measured through one meter. They are single phase, 60 hertz and 120/240 volts alternating current.
