Estimate how much propane a residential pool heater burns per hour, per day, and per swim season.
Surface area = length × width for a rectangular pool. A typical 16×32 in-ground pool is ~512 sqft.
Standard residential propane pool heaters run 80–84%. High-efficiency models hit 88–95%.
Average run time once the pool is at temperature — most setups cycle 3–6 hours/day.
gallons per swim season
576 gal
Pool-heater BTU demand follows the manufacturer planning rule:
BTU/hr ≈ surface area (sqft) × 12 × (target temp − ambient temp)
The constant 12 is the per-degree heat-loss coefficient published by major US pool-heater manufacturers (Hayward, Pentair) for an uncovered pool with no wind. A solar or thermal cover cuts heat loss to roughly 40% of the uncovered figure.
Estimate only — actual burn varies with wind, evaporation, splash-out, and how long the heater takes to bring the pool up from a cold start. A rough rule: solar covers cut consumption 30–60%; raising the target by 10°F roughly doubles fuel use.
