We’ve all been there before…you get that first toe in the water and BOOM, an icy chill runs up your spine.

Water temperature is the key factor in determining when it’s time to open or close your pool. But, for many, pool season never seems to last long enough. Others may simply want to feel comfortable swimming during chilly mornings or evenings.

Whatever the reason, there are several heating options pool owners can consider when trying to extend their pool season or hours of comfortable use and each has its own benefits. Before making any decision it’s important to consider your climate, swimming habits, budget and pool size.

Gas heaters—propane or natural gas—are the most expensive option, but provide the highest power and reliability. Typically gas heaters are ideal for large pools that require occasional heating or for spas, because extended run times can become expensive. Fast warm up times and the ability to hold consistent temperatures no matter the weather are often their most desirable features. A professional installation is recommended due to the need for a propane tank or natural gas hookup.

Oil-fired heaters are an alternate choice when natural gas or propane is unavailable in your area. Oil-fired heaters are not a common selection, but do provide similar results to gas heaters.

Heat pumps rely on electricity and are less expensive than gas heaters, but provide less heating power. Heat pumps take in the surrounding air, heat it and then directly transfer the heat to your water, making them better for warm regions. Heat up times are longer than gas, so heat pumps are not effective on spas or large pools. The advantage to heat pumps is their efficiency over gas heaters and their lower operating cost when matched with midsized pools in warm climates. Heat pumps can use up to 80 percent less energy than gas heaters.

Solar-based heaters utilize the sun’s heat to their advantage. Your already installed pump runs water through a heating station that is heated by the sun and located on the roof of a nearby structure. While it’s the least expensive option, it’s only effective on clear days during daylight hours. These limitations make it ideal for owners who don’t use their pools at night or in cloudy weather. However, solar pumps are the most eco-friendly solution to heating, and are great in sunny regions with warm climates.

Take the extra time and talk to a pool pro or even your neighbors about what heater is best for your area.
