10 Best Heat Pump For Above Ground Pools 2025 in the United States

The Aquastrong 35,000 BTU Inverter Heat Pump is a solid choice for above-ground pool owners looking to extend their swimming season. It offers a good heating capacity of 35,000 BTU, capable of warming pools up to 9,000 gallons, which fits well with many average-sized pools. Its inverter technology is a standout feature, providing a high energy efficiency with a COP of 15.8, meaning it uses electricity smartly to save on running costs compared to traditional electric or gas heaters. This pump is also climate friendly, with automatic defrost cycles that keep it running smoothly through colder months. Noise is kept low at about 48 decibels, so it won’t disturb your outdoor relaxation.

Installation is user-friendly thanks to multiple hose and pipe adapters, making it compatible with common pool setups. The heat pump also includes WiFi control, so you can easily adjust settings remotely via an app, which adds convenience. One thing to note is its weight (around 117 pounds), so positioning it might require some effort. While it comes with a 3-year warranty, some users might prefer a longer coverage given the investment.

The Aquastrong pump delivers a balance of efficient performance, user-friendly features, and durability, making it a practical option for pool owners in cooler climates or those wanting better temperature control without noisy or costly operation.

The Raypak Heat Pump 8450 is a solid choice for above-ground pool owners who want reliable and efficient heating. With a powerful 140,000 BTU heating capacity, it can warm medium to larger pools effectively. Its spiral titanium heat exchanger is a standout feature—this material resists corrosion well, which means it can handle harsh pool chemicals and last longer than standard models. The scroll compressor used here is known for being quieter and more energy-efficient compared to older piston types, so you get a good balance of performance and lower noise levels.

The powder-coated steel cabinet and composite base add durability by protecting against weather damage and rust, helping the unit to withstand outdoor conditions for years. Installation should be relatively straightforward with its offset 2-inch PVC plumbing connections, which fit common pool plumbing sizes. However, the unit is quite heavy (over 400 pounds), so professional installation might be necessary. Raypak's design suggests it performs best in moderate to warmer climates, as heat pumps generally operate less efficiently in low temperatures.

Customer reviews average 4.4 out of 5 stars, indicating good user satisfaction, though the price and size might be considerations for smaller pools or budgets. This model suits pool owners looking for a durable, efficient heater with quieter operation and long-lasting components, particularly for midsize to large above-ground pools in moderate climates.

The DR. INFRARED HEATER DR-900HP is a powerful heat pump designed to warm both in-ground and above-ground pools up to 28,000 gallons, making it suitable for medium to large pools. Its 90,000 BTU heating capacity is strong, ensuring your pool can reach comfortable temperatures relatively quickly. The Full DC Inverter technology allows the unit to adjust heating output from 20% to 100%, which improves energy efficiency and contributes to a high Coefficient of Performance (COP), meaning it uses electricity smartly to produce more heat. This can help reduce your electricity bills compared to traditional pool heaters.

One standout feature is the built-in WiFi and app control, offering convenient remote scheduling and temperature adjustments from anywhere. This smart control, combined with the soft-start function, helps prolong the unit’s lifespan by preventing stress on the compressor during startup. The twin rotary compressor design also reduces vibration and noise, so it operates more quietly than many other models.

Durability is well-addressed with CSA and AHRI certifications indicating the unit meets industry standards for quality and performance. While the product comes with good customer support based in the USA, the heat pump is made in China, which may be a consideration for some buyers. It weighs 187 pounds and measures about 43 x 16.5 x 37.7 inches, so installation might require some effort or professional assistance. The power requirement (208-230V) might not be compatible with all home electrical setups, and while it is designed for above-ground and in-ground pools, its large size and weight could make it less ideal for smaller pools or limited spaces. Noise is reduced due to design improvements but could still be noticeable depending on placement. This heat pump is well suited for pool owners seeking a high-capacity, energy-efficient, and smart-controlled solution for medium to large pools in various climates. It balances strong heating performance with durability and user-friendly features, though installation and electrical needs should be carefully considered.
