Single package heat pumps

Energy Efficiency Regulations

Regulatory definition

Single package central heat pump, a single-phase or three-phase air-to-air central heat pump that is a centrally ducted single package unit and has a cooling or heating capacity of less than 19 kW (65,000 Btu/h). It does not include a single package vertical heat pump.

Compliance date

Manufactured on or after January 1, 2025, for single package central heat pumps (single-phase)

Manufactured on or after January 1, 2026, for single package central heat pumps (three-phase)

For models manufactured prior, refer to the Regulations

Compliant product models

Single package heat pumps, single-phase as listed on NRCan’s searchable database

Single package heat pumps, three-phase as listed on NRCan’s searchable database

Testing standard

10 C.F.R. Appendix M1 for single-phase models

10 C.F.R. Appendix F1, except that the very low temperature heating test (H4) must be conducted.

Energy efficiency standard

Energy performance standard for single package central air conditioners and single package central heat pumps under 19 kW (65,000 Btu/h)

Single Phase

Energy-using product	Energy performance standard
Single package central heat pumps, other than those that are space-constrained	SEER 2 ≥ 13.4 HSPF 2 (Region V) ≥ 5.4 Off mode power consumption ≤ 33 W
Single package central heat pumps that are space-constrained	SEER 2 ≥ 11.9 HSPF 2 (Region V) ≥ 5.0  Off mode power consumption ≤ 33 W

 

Three-phase

Energy-using product	Energy performance standard
Single package central heat pumps, other than those that are space-constrained	SEER ≥ 13.4 HSPF (Region V) ≥ 5.3
Single package central heat pumps that are space-constrained	SEER ≥ 13.9 HSPF (Region V) ≥ 5.3

Seasonal energy efficiency ratio (2) – the total cooling of a heat pump in Btu during its normal annual usage period for cooling, divided by the electric power usage in watt-hours during the same period in accordance with 10 C.F.R. Appendix M1/10 C.F.R. Appendix F1.

Heating seasonal performance factor (2) (Region V) – the total heating output of a heat pump during its normal annual usage period for heating, divided by the total electric power input in watt-hours during the same time period in accordance with 10 C.F.R. Appendix M1/10 C.F.R. Appendix F1.

kW = kilowatts
Btu/h = British thermal units per hour
