The following is an example of language you may wish to require in your upcoming contract:

The Vendor Must:
Provide single or multi-speed geothermal (GeoExchange) heat pumps that earn the ENERGY STAR and meet the ENERGY STAR specifications for energy efficiency as outlined below. The vendor is encouraged to visit energystar.gov for complete product specifications and an updated list of qualifying products.

Product Type Current Criteria
EER COP
Closed Loop System
With integrated water heater		 14.1
14.1		 3.3
3.3
Open Loop System
With integrated water heater		 16.2
16.2		 3.6
3.6
DX System
With integrated water heater		 15
15		 3.5
3.5

NOTE: These specifications apply to single-speed models. Multi-speed models may be qualified based on EER = (high speed EER+low speed EER)/2; and COP = (high speed COP+low speed COP)/2.

Additional considerations for the procurement official:

Request that the vendor ensure:

  • the heat pump is properly sized for the conditioned space to ensure optimal operational cycles and comfort using industry accepted sizing protocols such as ACCA's Manual J or N as appropriate.
  • contractors are properly trained on the following issues:
    • equipment installation and hookup,
    • domestic water heater connection for desuperheater or integrated water heating, and
    • code compliance.
