Best Above-Ground Pool Heaters

Want to keep your pool warm without worrying about heater operating costs? The Intex Pool Heater Solar Mat is the ideal fit for your backyard because it uses solar technology to warm up the water. It works with many pool pumps and is quick and easy to set up. However, it requires direct sunlight to work effectively, so it isn't the best choice if your pool is located in a shady spot.

If you want an above-ground pool heater that can warm your pool water quickly and effectively, look no further than the Hayward W3HP50HA2. It features advanced heat pump technology, so it uses less energy than gas heaters. It is quieter than other models, too, which means you won't bother your neighbors. It is very pricey, though, so you'll want to consider other options if you're on a budget.

The Raypak 106A is the perfect fit for your above-ground pool if you want to warm up your water as quickly as possible. It is one of the brand's smallest pool heaters, but it still delivers 150,000 BTUs of heating power with propane for faster heating. It isn't as energy-efficient as other heaters, though, so you may want to look elsewhere if energy costs are a dealbreaker.
