Saskatchewan's Green Directory Helping Saskatchewan choose a better environment

Ground source heat pumps (GSHPs), geoexchange (geothermal) heating / cooling systems criteria

  1. Minimum heating coefficient of performance rating of 4.2
  2. Minimum cooling EER of 16.5 (COPc >4.8)
  3. Designers and installers of heat pump systems should be able to demonstrate accreditation through the Canadian Geo-Exchange Coalition or the International Ground Source Heat Pump Association.

Publicly quoted COPh and EER values should be determined according to CAN/CSA 13256-1 by a reputable laboratory. The criteria set here are somewhat tougher than those used for EnergyStar rating. Only closed loop models currently meet our criteria. [In any case there are additional environmental complications with open loop systems].

A full current list of GSHPs meeting our criteria is included. (The information was sourced from the EnergyStar Canada website, which for the purposes of this directory is considered an authoritative source of test results.)
