10 Best Above Ground Pool Heaters 2025 in the United States

The TURBRO 50,000 BTU Swimming Pool Heat Pump offers a range of features that can enhance your swimming experience, particularly in cooler climates. One of its notable strengths is its inverter technology, which intelligently adjusts heating power to maintain a stable water temperature. This is complemented by its high energy efficiency, with a COP rating of up to 16.2, making it a cost-effective choice compared to natural gas or propane heaters.

Additionally, it is suitable for both in-ground and above-ground pools up to 16,000 gallons, and even larger pools up to 21,100 gallons, but not recommended for inflatable pools. The unit is also WiFi enabled, allowing remote control and monitoring via a smartphone app, which adds a layer of convenience. Safety features include multiple built-in sensors to monitor various operational parameters, ensuring safe use and preventing damage.

The TURBRO heat pump requires professional installation, which might be a drawback for some users. It's also most efficient when outdoor temperatures are above 60°F, so its performance may be less optimal in colder conditions. Another consideration is its size and weight, as it is quite large and heavy (146.3 pounds and dimensions of 25.9 x 15.7 x 38.5 inches), which might be cumbersome for some setups. Those looking for a simple plug-and-play solution might find this product less suitable. If you're in the market for a smart, energy-efficient pool heater and are prepared for the professional installation, the TURBRO Beluga series could be a great fit for your needs.

The Raypak Crosswind V Pool Heat Pump is designed as a versatile heater suitable for both above-ground and in-ground pools, making it a flexible option if you might change pool types in the future. It uses a hybrid heating system that smartly switches between gas and electric sources to keep energy costs down while maintaining a comfortable pool temperature. This feature is great if you want to save on utility bills and enjoy consistent warmth.

The heater is built with durability in mind, featuring a powder-coated metal cabinet and a titanium heat exchanger, which should stand up well to the outdoor environment and provide long-lasting operation. Installation and maintenance may require professional help due to its size and weight (over 280 pounds and roughly 34 inches in each dimension), especially if space is limited. Its Wi-Fi connectivity allows you to control and schedule the heater remotely via your phone, adding convenience and modern smart-home integration.

The hybrid heating system relies on access to gas for the most cost-effective operation, and the Raypak Crosswind V suits pool owners seeking a durable, energy-conscious heater with smart features, particularly in climates where maintaining pool temperature year-round is important.

The Aquastrong 75,000 BTU Inverter Swimming Pool Heat Pump is a strong choice for above-ground pool owners who want to extend their swim season, thanks to its dual heating and cooling capabilities. It can heat pools up to 21,000 gallons, making it suitable for most medium to large above-ground pools. The powerful 75,000 BTU output means it can warm water quickly, even in cooler climates. One standout feature is its energy efficiency — it uses advanced inverter technology to save up to 70% energy compared to traditional electric heaters and runs quieter than many similar models, producing only about 53 dB of noise. This makes it less intrusive while operating.

The heater’s smart WiFi control lets you adjust settings and monitor energy use remotely, adding convenience for busy users. Installation is straightforward with multiple adapter options that fit common pool plumbing sizes, although the unit is quite heavy (218 pounds), which might require some help to position. It’s built with durable cast iron and includes an auto-defrost function that keeps it running smoothly through cold weather.

Since it requires a 220V power supply, you may need to check your home’s electrical setup before purchase. Despite being larger and heavier than some other models, its strong heating power, energy savings, and smart features make it an ideal option for pool owners seeking reliable, year-round temperature control with minimal hassle.
