Disclaimer:

This calculation uses the thermal energy conservation method: Total BTUs = (Volume × 8.34 × ΔT). A 2.0x efficiency factor is applied to account for heat loss to the environment during the heating process.

Actual heating performance may vary depending on several factors, including:

• Use of a pool cover (highly recommended)
• Wind exposure and ambient air temperature
• Humidity levels and sun exposure

For air temperatures below 50°F (10°C), heat pump efficiency drops significantly and heating times will increase.
