Calculation Details:

• Running Current: Power ÷ 12V = Current at full load
• Usable Capacity: Battery Capacity × Discharge Rate
• Runtime: Usable Capacity ÷ Running Current

This calculator provides estimates for 12V DC systems. Actual runtime may vary based on battery condition, temperature, and usage patterns.

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.
