Northeast Georgia summers are long, but a heater turns a three-month pool into a seven- or eight-month one — comfortable swimming from spring through late fall, and a spa you can use year-round. Here’s how the three main heating options compare, and which tends to make the most sense in our climate.
For most Georgia pools, an electric heat pump is the sweet spot. Instead of creating heat, it moves warmth from the surrounding air into the water, which makes it remarkably efficient — often delivering four to six units of heat for every unit of electricity it uses. The catch is that it works best when the air is above roughly 50°F and it heats gradually. In zone 8a that’s a perfect match: our shoulder seasons are mild, so a heat pump extends the season cheaply without the high running cost of gas.
Natural-gas or propane heaters heat fast and work in any weather, which makes them ideal for spas and for owners who want the pool warm on demand rather than maintained all season. The trade-off is operating cost — gas heaters are cheaper to buy but more expensive to run, so they shine for quick, occasional heating rather than holding temperature for weeks.
Solar collectors use the sun to warm your water and have the lowest operating cost of all — essentially free heat once installed. The limitations are that performance depends on sunshine and you need adequate panel area (usually on the roof). Many owners pair solar with a heat pump so the sun does the work when it can and the heat pump fills the gaps.
A heated pool also pairs naturally with a cover to hold the warmth overnight and an automation system to schedule heating efficiently — both of which we design in from the start. See how it all comes together in smart pool technology.
Sizing depends on your pool's surface area, the temperature you want, and how fast you want to get there. Bigger water surface loses more heat, so larger pools need more capacity. A gas heater is rated in BTUs; a heat pump in BTUs and by the air temperature it can work in. Undersize it and the pool never quite reaches temperature on cool days — we calculate the right size for your specific pool and goals.
The single biggest money-saver is a cover — a pool loses most of its heat off the surface overnight, and a cover keeps it in. Beyond that, run heating on a schedule through automation, set a sensible target temperature, and consider pairing a heat pump with solar so the sun does the free work. Efficient heating is as much about holding heat as making it.
Keep the area around the unit clear, keep your water chemistry balanced (unbalanced water corrodes heat exchangers fast), and have it serviced periodically. A well-maintained heat pump or gas heater lasts many years; neglected chemistry is what kills them early. Balanced water protects every piece of equipment downstream.
An electric heat pump is usually the best value here — our mild shoulder seasons let it extend the swim season efficiently. Gas is better for fast, on-demand heat and spas.
It depends on the heater type, your target temperature, and whether you use a cover. A cover is the biggest single way to cut heating costs by holding heat overnight.
You can comfortably extend to roughly March–November with a heat pump, and use a heated spa year-round. True winter swimming usually needs gas heat.
