Your Pool Heater Choices
There are three major types of swimming pool heaters: solar, electric heat pump and gas. While we believe the vast majority of pool owners are best served by a solar pool heater, your unique circumstances and needs may dictate a different choice. This page briefly describes the three major types of pool heating and the strengths and weaknesses of each.
Solar pool heating is by far the most cost-effective way to heat your pool. The sun’s energy is clean, free and inexhaustible. And plentiful in Florida on a year-round basis. While solar does not have the ability to deliver any temperature on demand in any weather, you will never have to turn your solar pool heater off because you can no longer afford its operating cost.
Swimming pool heat pumps work just like central air conditioning heat pumps, only in reverse. Instead of removing heat from the inside of your home and expelling it to the outside air, a pool heat pump takes heat out of the outside air and transfers it into your pool water. Swimming pool heat pumps can extract useful heat energy in air temperatures as low as 45–50°F, so they are very effective in Florida’s mild climate.
Gas pool heaters, which burn either propane or natural gas, can maintain your pool at pretty much any temperature you desire. The advantage of gas is the ability to maintain any temperature in pretty much any weather. With today’s high and rising fuel costs, we recommend that a gas heater be installed only as a backup system to supplement a primary solar pool heater or pool heat pump when 85–90°F pool water temperatures are medically required.
