How to Pick a Pool Heater
Gas heater, heat pump, or solar. Climate determines best fit.
Gas heater
Heats fast. Works any temperature. $4,800-$11,500 installed. Best for occasional use + cold climates.
Heat pump
Energy-efficient (COP 5-6). Heats slowly. Needs ambient air >50F. $5,800-$11,500 installed. Best for mild climates + daily use.
Solar
Lowest operating cost. Slowest. $4,800-$8,500 installed. Best as supplement to gas or heat pump.
