Frequently Asked Questions
What is the best gas pool heater for an inground pool?
The best gas pool heater for an inground pool depends on pool size, usage frequency, and local gas prices. Leading brands include Hayward, Pentair, and Raypak. Look for a unit with a corrosion-resistant heat exchanger, a high-altitude rating if applicable, and an ASME certification for safety.
How do I size a gas pool heater for an inground pool?
Use the formula: pool surface area (sq ft) × temperature rise (°F) × 12 = minimum BTU required. For a 600 sq ft pool needing a 10°F rise, that is 72,000 BTU minimum — so a 100,000–150,000 BTU unit provides a good margin. Larger pools or colder climates need more capacity.
How long does a gas pool heater take to heat an inground pool?
A gas pool heater raises water temperature approximately 1–2°F per hour per 10,000 gallons. A 20,000-gallon pool needing a 10°F rise will take roughly 5–10 hours with a 200,000–400,000 BTU heater, assuming no significant heat loss to wind or evaporation.
Can gas pool heaters be used with a variable-speed pool pump?
Yes, but the pool pump must provide the minimum flow rate specified by the heater manufacturer (typically 20–60 GPM) to protect the heat exchanger from overheating. Program the variable-speed pump to maintain adequate flow whenever the heater is operating.
Should a gas pool heater be covered when not in use?
A weatherproof cover or heater enclosure helps protect the igniter and controls from moisture and debris. However, ensure the cover does not block the heater’s air intake or exhaust. Most manufacturers offer optional covers; confirm the model’s ventilation requirements before covering.
