Air source heat pumps operate effectively across a dynamic temperature spectrum, typically maintaining optimal performance between 32°F and 68°F. These innovative systems can function in temperatures ranging from -4°F to 115°F, with efficiency varying significantly based on environmental conditions, technological enhancements, and specific model capabilities. Understanding the precise temperature range is crucial for homeowners seeking maximum energy efficiency and consistent indoor comfort.
What Determines Air Heat Pump Temperature Performance?
How Do Temperature Ranges Impact Heat Pump Efficiency?
Heat pump efficiency is directly correlated with outdoor and indoor temperature variations. The Coefficient of Performance (COP) serves as a critical metric in evaluating system performance across different temperature ranges.
Temperature Performance Metrics
| Temperature Range | Heating Efficiency | Cooling Efficiency | COP Value |
|---|---|---|---|
| Below 32°F | Decreased | Not Applicable | 1.5-2.5 |
| 32°F – 68°F | High | Moderate | 3-4 |
| Above 68°F | Low | High | 2.5-3 |
