Program Scope
All production models of water-to-air and water-to-water heat pumps consisting of ground-water heat pump equipment, water-loop heat pump equipment, and ground-loop heat pump equipment, rated below 39,500 W (135,000 Btuh) at ISO Standard Rating Conditions (Cooling), manufactured for sale in North America and as covered by the Standard, shall be included in this Program. Each consists of one or more factory-made assemblies which include an indoor conditioning coil with air moving means, compressor(s), and refrigerant-to-water heat exchanger(s), including means to provide both cooling and heating, cooling only, or heating only functions. When such equipment is provided in more than one assembly, the separate assemblies shall be designed to be used together, and the requirements of rating outlined in the Standard are based upon the use of matched assemblies.


Certified Ratings
The following certification program ratings are verified by test:
  • Standard Rating Cooling Capacity, Btuh
  • Energy Efficiency Ratio, EER, Btuh/W
  • Standard Rating Heating Capacity, Btuh
  • Coefficient of Performance, COP
  • Part Load Standard Rating Cooling Capacity, Btuh (if applicable)
  • Part Load Energy Efficiency Ratio, EER, Btuh/W (if applicable)
  • Part Load Standard Rating Heating Capacity, Btuh (if applicable)
  • Part Load Coefficient of Performance, COP (if applicable)
