10 Best Pool Heat Pumps 2025 in the United States

The Aquastrong Inverter Swimming Pool Heat Pump is a powerful choice for those with large pools up to 26,000 gallons, offering a strong heating capacity of 100,000 BTU. It uses inverter technology to achieve a high efficiency with a COP of 15.8, meaning it saves significant energy compared to traditional electric or gas heaters. This makes it a smart pick if you want to keep energy costs down while maintaining warm pool water. It also has the flexibility to cool the water, which is a nice bonus for warmer months.

One of its standout features is the quiet operation at around 55 dB, so it won’t be disruptive while running. The automatic defrost system keeps it working smoothly in cold weather, extending the swimming season without hassle. Control is very convenient with a smartphone app and timer, letting you easily adjust temperature and monitor energy use remotely.

Installation should be straightforward thanks to multiple connection options that fit most pool setups. The build uses durable cast iron parts, which should help the unit last for several years. However, keep in mind the heat pump is quite heavy (over 200 pounds), so you may need help moving and setting it up. This heat pump is well-suited for pool owners wanting a reliable, energy-efficient system that covers both heating and cooling needs with smart, easy controls. It may be less ideal if you have a smaller pool or prefer a lighter, more portable unit. Its price and 3-year warranty also reflect its solid build and performance level.

The Hayward W3HP50HA2 HeatPro Heat Pump is a solid choice for pool owners seeking efficient and reliable heating. One of its key strengths is its advanced heat pump technology, which uses less energy compared to natural gas and propane heaters, making it a cost-effective option. With a high coefficient of performance (COP), it ensures efficient heating even in harsh weather conditions. The digital control panel is user-friendly, allowing for easy temperature adjustments and other settings.

The unit operates quietly, thanks to an efficient rotary compressor and low-noise fan, which is a significant advantage for maintaining a peaceful poolside environment. The durable titanium heat exchanger offers excellent corrosion protection, enhancing the unit’s lifespan and reliability. However, the product's weight and dimensions (152 pounds, 17 x 43 x 30 inches) might make installation and handling a bit challenging, potentially requiring professional help.

The Hayward W3HP50HA2 HeatPro Heat Pump is AHRI certified and lab-tested, ensuring high quality and performance standards, but it’s important to consider the possible need for professional installation and its space requirements when making a purchase decision.

The TURBRO Beluga B75V pool heat pump is a solid choice if you want to extend your swimming season during cooler months without using gas or propane. With a strong heating capacity of 75,000 BTU and a high efficiency rating (COP up to 16.2), it can heat medium to large pools (up to around 21,000 gallons) while helping save on energy costs. The inverter compressor adjusts heat output based on conditions, keeping water temperature steady and reducing power waste.

It’s built tough with a titanium heat exchanger that resists corrosion, making it suitable for saltwater or seawater pools. You can control the pump easily via its onboard panel or a smartphone app, including setting timers for convenience. Safety is well-covered with multiple sensors that monitor performance and automatically shut down if something goes wrong. It’s best operated when outdoor temperatures are above 60°F, meaning its efficiency and heating power drop in colder weather.

Installation requires a professional electrician for the high-voltage connection, and some parts like water hoses and filters aren’t included, so additional setup costs should be expected. This pump is not suitable for inflatable pools due to water pressure needs. For standard above-ground or in-ground pools, the TURBRO Beluga B75V provides an energy-efficient, durable, smart, and safe electric heating solution.
