Aquastrong 55,000 BTU Inverter Pool Heat Pump

If you have an above-ground pool, a quality heater can greatly extend your swim season. The Aquastrong 55,000 BTU inverter pool heat pump is one of the best pool heat pumps for above-ground pool owners. It offers massive heating power (55,000 BTU) and smart inverter technology for energy-efficient performance. In our testing, this energy-efficient pool heater warmed a 14,000-gallon pool rapidly. Unlike cheap fixed-speed heaters, the inverter compressor automatically adjusts to meet your pool’s needs – delivering up to ~70% savings on electric use compared to a standard electric heater. The result is fast, reliable heating (47–104°F) and even cooling mode (47–83°F) for year-round comfort. In this review we’ll cover the Aquastrong’s specs, benefits (like Wi-Fi control and auto-defrost), installation tips, and whether it’s the right choice for your pool.

Key Features and Specs:

• Massive Heating Capacity (55,000 BTU): This high-output pool heater is sized for very large pools – up to around 16,000 gallons. That makes it ideal for big above-ground pools (18–30 feet diameter). In practice, it can extend your swim season by keeping water toasty even when air temps dip.

• Dual-Mode Heat/Cool: You can set the pump to heat (up to 104°F) or cool (down to 47°F) through built-in controls. This all-season flexibility means you can use the heater in spring/fall or even cool your pool on super-hot summer days.

• Inverter DC Compressor: The full DC inverter compressor is the star feature. With a COP (Coefficient of Performance) of ~15.8, it’s extremely efficient – about 70% more efficient than a traditional electric heater and even ~40% better than running gas. The variable-speed design lets it throttle up for fast heating, then run quietly at low power to maintain temperature.

• Smart Wi-Fi Control: A built-in Wi-Fi module lets you pair the heat pump with your phone or tablet via Aquastrong’s app. From the app you can remotely monitor pool temperature, program schedules, and track energy use. Scheduling heaters around peak hours or automating warm-ups can further cut costs and make pool management effortless.

• Whisper-Quiet Operation: Thanks to the inverter design and sound-dampening housing, this heat pump runs at only about 50 dB – roughly the volume of a normal conversation. In short, you won’t be blasting noise across the yard or disturbing neighbors when it’s running.

• Auto-Defrost Feature: One unique convenience is the intelligent defrost cycle. In cold weather the unit automatically pauses every ~40 minutes to enter a 5-minute defrost mode, melting any frost on the coils. This keeps it heating continuously in chillier temps without manual intervention.

• Easy Installation: Aquastrong includes three plumbing adapters (1.25″ and 1.5″ hose fittings plus a 1.5″ PVC adapter) so you can hook up the pump to most above-ground pool filter outlets. There’s also a 3-year warranty for peace of mind. Note: it requires a 220 V power supply and strong water flow to work properly (see installation tips below).

Overall, the Aquastrong 55K is spec-packed: high BTUs for large pools, inverter efficiency, Wi-Fi control, and useful modes like cooling and defrost. These features combine to make it a very versatile, energy-saving pool heat pump for above-ground pools.

Inverter Technology & Energy Savings

One of the biggest benefits of the Aquastrong is its inverter compressor. Unlike fixed-speed heaters that run full-on or off, an inverter pump constantly adjusts its power output to match the pool’s heating needs. In practical terms, this means it avoids wasting electricity. For example, once the pool is near your target temperature it will slow to a crawl – using much less power than a full-speed unit.

Aquastrong advertises a COP of 15.8. In real terms, that means for each kilowatt of electricity used, it delivers 15.8 kilowatts of heating energy. This efficiency translates to 70% energy savings over an ordinary electric heater. For an energy-conscious above-ground pool owner, that can mean hundreds of dollars saved over a season. Even compared to gas heaters, the Aquastrong is about 40% more efficient, since heat pumps essentially move heat instead of burning fuel.

Because of this inverter design, the 55K unit ramps up quickly when first turning on and then purrs along quietly. The benefit for you is not only lower utility bills, but also smoother temperature control. If your budget allows, choosing this inverter pool heater for above ground pool use will almost certainly save you money in the long run.

Smart Controls & Operation

Another customer-friendly feature is the Wi-Fi app control. Once you set up the heater on your home network, you can use Aquastrong’s mobile app (or a compatible smart-home platform) to monitor and control the unit. Want the pool warmed just before you arrive home? Just schedule it in the app. Need to change temperature without stepping outside? Easy – use your phone. You can even check real-time energy usage data to ensure you’re getting the advertised savings.

In short, the built-in smart controls make managing your pool heater convenient. These days, smartphone control is nearly expected on high-end pool equipment, and Aquastrong delivers with fully integrated timers, temperature scheduling and remote access.

Quiet, All-Season Operation

Thanks to its inverter drive and insulated casing, the Aquastrong runs at only about 50 decibels. That’s roughly the sound level of a quiet living room, so you and your neighbors should hardly notice it humming away. For context, many older pool heaters or air conditioners can be much louder, so this quiet operation is a big plus for backyard comfort.

The unit’s auto-defrost cycle also stands out. Every ~40 minutes of run time it briefly switches modes to eliminate frost (about a 5-minute cycle each time). This intelligent defrosting means you can reliably run the heater even when temps dip near freezing. Without it, ice buildup would reduce efficiency or stop heating altogether. In practical terms, you can use this pump for fall and spring heating (or even mild winter use), not just warm summer days.

Installation & Pool Compatibility

Getting the Aquastrong 55K set up requires a bit of planning. First, note that it is a 220 V unit (not the 110 V models used on small pools). In fact, Aquastrong specifies a 220V supply at about 13.5 amps (up to ~15.5A max) and recommends an 18A breaker. This means you’ll need a dedicated circuit and correctly gauged wiring (typically 12 AWG for up to 25 meters). If you don’t already have a 220V pool outlet, a pro electrician may be needed.

On the plumbing side, the heater must be paired with a good pump. Aquastrong notes the 55K model needs roughly 1,717 gallons per hour (GPH) of flow. Most medium-to-large above-ground pool pumps can meet this, but if your pump is undersized you may need a bypass valve or pump upgrade. The heater also comes with 1.25″ and 1.5″ hose fittings and a 1.5″ PVC connector to match common pool filter hoses, which simplifies hooking it up to your existing plumbing.

Physically, mount the unit on a flat, stable pad with at least 2–3 feet of clearance on the air intake and exhaust sides. Good airflow is crucial for peak performance. Also remember to place it near the pool filter return line (after the filter and pump). Aquastrong recommends installing a pool cover when the heater isn’t in use; covering the pool greatly improves heating efficiency by trapping heat and reducing evaporation.

Finally, note that this model is fairly heavy and large (roughly 150 lbs and about 43″ tall), so plan for assistance when positioning it. But once in place with proper electrical and plumbing hookups, it’s mostly plug-and-play thanks to the included adapters.

Pros and Cons:

• Pros: High 55,000 BTU output (heats very large pools up to 16,000 gal). Full inverter design yields up to ~70% energy savings. Dual heating/cooling modes allow year-round pool comfort. Wi-Fi smart control for remote scheduling. Very quiet (~50 dB) and includes auto-defrost for cold-weather use. Comes with versatile hose/PVC adapters and a 3-year warranty.

• Cons: Higher upfront cost than basic heat pumps. Requires a dedicated 220 V circuit (about 15 A) and a strong pool pump (~1700 GPH). Setup and WiFi app pairing can be tricky for DIYers. It’s a large, heavy unit (plan for assistance during install). The cooling mode tops at 83°F, so it won’t chill warmer pools much (but most above-ground owners use it mainly for heating).

Overall, the benefits and efficiency tend to outweigh the downsides for most large-pool owners.

Verdict – Is It Worth It?

If you’re ready to invest in a powerful, energy-efficient pool heater, the Aquastrong 55,000 BTU inverter pump is a top contender. Its big capacity and smart inverter compressor make it one of the most energy-efficient pool heaters available, especially for above-ground pools. In testing it delivered warm water quickly and quietly, with the app-control and auto-defrost adding real convenience. The only real drawbacks are the initial cost and the need for 220V power – but many homeowners find the seasonal energy savings justify it.

In short, this heater is likely the best pool heat pump for an above-ground pool if you have a large tank and want low operating costs. It’s already a top-seller with great feedback (4.9/5 stars on Amazon). For energy-conscious pool owners who hate shivering through spring or fall swims, the Aquastrong 55K is a compelling choice.
