This increased effort can lead to a reduction in efficiency, measured by the heating seasonal performance factor (HSPF). The efficiency and capability of a specific model are directly defined by its operational range in low-temperature conditions.
Heat Pump Low Temp Specification Guide: Understanding Operational Limits
As the outdoor temperature approaches the heat pump minimum outdoor temperature , the system must work harder to maintain indoor warmth. Today's units utilize low-temperature refrigerants and variable-speed inverter compressors.
This backup, often in the form of electric resistance heating or a gas furnace, activates when the heat pump minimum outdoor temperature is reached or exceeded. Cold-climate heat pumps are specifically engineered to handle the heat pump minimum outdoor temperature of their target region.
