Internal water-loop heat pumps
Energy Efficiency Regulations
Regulatory definition
Internal water loop heat pump, a water-source single package or split-system heat pump that is factory-built, is intended for installation in an internal water loop systems and has a cooling or heating capacity of not more than 40 kilowatts (135 000 Btu/h)
Compliance date
Manufactured on or after February 3, 1995
For models manufactured prior, refer to the Regulations
Testing standard
CAN/CSA-C13256-1
Energy efficiency regulations by province
Some provinces also have their own energy efficiency regulations for many of the federally regulated products – find out which ones!
Energy efficiency standard
| Product type | Mininum COP | |
|---|---|---|
| Cooling COPc | Heating COPh | |
| November 2006 | ||
| Cooling capacity < 5 kW |
≥ 3.28°C with 30°C inlet water | ≥ 4.2°C with 20°C inlet water |
| Cooling capacity ≥ 5 kW and ≤ 40 kW |
≥ 3.52°C with 30°C inlet water | ≥ 4.2°C with 20°C inlet water |
Where:
COP = Coefficient of performance – a ratio for both the cooling COPc and heating COPh modes calculated by dividing the capacity expressed in watts by the power input in watts, excluding any supplementary heat
kW = kilowatts
