Most Cost-Effective Ways to Run Your Pool Heater

Extend swim season affordably by optimizing pool heater use. The key factors: heater size, timing, type, and temperature management.

Right-Size Your Heater

Match BTU output to pool surface area and desired temperature rise. Example: 500 sq ft pool, 15°F rise → 105,000 BTU. Oversizing wastes energy; undersizing struggles.

Heat Smart, Not Constantly

• Unused for days? Let it cool; reheat 24 hrs before use.
• Regular use? Keep heated, but use a solar cover to cut heat loss and cost dramatically.

Choose Efficient Heater Types

• Low NOx burners (required in many CA counties) = higher efficiency.
• Induced draft = hotter combustion.
• Avoid millivolt (standing pilot) = constant gas waste.

Set Temperature Thresholds

78°F is comfortable for most. Run heater only when water drops below this. Warm water tolerates cool air (50s/40s°F) comfortably.
