Options for heating the pool include solar energy, fossil fuels (LP gas, natural gas or oil), and heat pump. Each option has its own advantages and disadvantages. Solar pool heating is the most cost-effective use of solar energy in Florida.
Solar Pool Heater: A solar pool heating system usually costs between $3,000 and $4,000 to buy and install. They typically last longer than gas and heat pump pool heaters. Your actual cost and payback depend on many factors. Check with your local utility company to see if they offer rebates.
Gas Pool Heater: A gas pool heater is most efficient when heating a pool for short periods of time and is ideal for quickly heating pools. Therefore, gas pool heaters can be a good choice for pools that are not used on a regular basis. Unlike heat pump and solar pool heaters, gas pool heaters can maintain any desired temperature regardless of the weather or climate.
Heat Pump Pool Heater: Heat pumps use electricity to capture heat and move it from one place to another. They do not generate heat. Heat pump pool heaters generally cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, heat pump pool heaters typically last longer than gas pool heaters.
