10 Best Electric Pool Heaters 2025 in the United States

The TURBRO Beluga series swimming pool heat pump offers a heating capacity of 50,000 BTUs, making it suitable for pools up to 16,000 gallons. It's built with inverter technology to adjust heating power based on various factors like ambient temperature and water flow, ensuring consistent pool temperature. The COP rating of 15.90 suggests good energy efficiency, saving costs significantly compared to other heating methods such as natural gas or propane. However, it performs best when outdoor temperatures are above 60°F, which might limit its efficiency in colder climates. Using a pool cover can help mitigate this issue.

The unit is relatively large and requires professional installation due to its need for a hardwired connection to a 220-240 V power supply, which could add to initial setup costs and complexity. The titanium heat exchanger is a plus for durability and compatibility with saltwater pools. Control features are advanced, offering both a control panel and mobile app integration for convenience.

Safety features are robust, with multiple sensors monitoring various operational parameters and shutting down the system in case of faults. For those with above-ground or larger in-ground pools looking for an efficient and smartly controlled heating solution, this product could be a great fit, though it requires consideration of installation requirements and optimal operating temperatures.

The Aquastrong 75,000 BTU Inverter Pool Heat Pump stands out for its strong heating capacity, suitable for large pools up to 21,000 gallons. This means it can quickly warm your pool water even in cooler climates, extending your swimming season comfortably. Its dual heating and cooling modes provide flexibility, allowing you to both heat the water in cold weather and cool it on hot days, a feature not always found in similar products. The inverter technology is a big plus, as it adjusts power use efficiently, resulting in up to 70% energy savings compared to traditional electric heaters. This also helps reduce your electricity bills over time. The heat pump operates quietly at about 53 decibels, which won't disturb your outdoor relaxation. Additionally, it includes an intelligent auto-defrost system that keeps it running smoothly in winter by preventing frost buildup automatically.

Control-wise, it offers WiFi connectivity and an app, letting you adjust temperature settings and program schedules remotely, adding convenience especially if you’re frequently busy or away from home. The unit’s size and weight (218 pounds, about 18×29×43 inches) make it fairly substantial, so you’ll need adequate space for installation, but it comes with versatile connection adapters to fit different pool setups easily. Made with cast iron, the build quality suggests good durability, supported by a 3-year warranty for peace of mind.

The relatively large size and weight might require professional help during installation. While the product excels in efficiency and comfort features, it requires a 220V power supply, which may need specific electrical arrangements if your home doesn't already support it. This heat pump is a solid choice for pool owners looking for efficient, quiet, and year-round temperature control, especially for larger pools and those who value smart app-based operation.

The Raypak Heat Pump 8450 is a solid choice for anyone looking to heat a swimming pool efficiently. With a heating capacity of 140,000 BTUs, it can effectively warm large pools, making it suitable for both residential and light commercial use. The titanium heat exchanger is a standout feature, as it enhances durability and resistance to corrosion, which is ideal for pools with saltwater systems. This can lead to a longer lifespan compared to other materials, giving you peace of mind regarding maintenance and replacement costs.

One of the strengths of this model is its energy efficiency. It operates quietly thanks to a swept wing fan design, which is a great benefit if you're sensitive to noise or plan on using the pool in the evening. The build quality is robust, featuring a long-lasting steel outer case, ensuring that it can endure outdoor conditions.

There are some considerations to keep in mind. The weight of 422 pounds can make installation a bit challenging, especially if you are trying to set it up yourself. Ensure you have the necessary resources or professional help for installation. The Raypak Heat Pump 8450 is a well-rounded electric pool heater with notable efficiency and durability, making it a good fit for those who want reliable heating for their pools.
