Our take on the MINI Heat Pumps, Up to 18,000 BTU Inverter, for Pools up to 6,500 Gallons, 115V

The AQUASTRONG Mini is a compact inverter heat pump for above-ground pools up to 6,500 gallons. It both heats water to 104°F and cools it to 59°F, runs on a standard 115V outlet, and uses a titanium heat exchanger that resists chlorine and salt. Its COP of 5.5 and 38–48 dB sound rating compare well with conventional electric heaters, which cost far more to run and are louder. Owners like the easy install and quiet running, but several say undersized units heat slowly and that cold weather and an uncovered pool undercut performance.

About the MINI Heat Pumps, Up to 18,000 BTU Inverter, for Pools up to 6,500 Gallons, 115V

This is a mini inverter heat pump for above-ground pools up to 6,500 gallons. It heats pool water up to 104°F or cools it to 59°F. A thermostat holds the set temperature with ±2°F accuracy.

The heat exchanger is 100% titanium, which resists corrosion, chlorine and salt water. Internal screws, brackets and key components are made of rust-proof materials. An auto-defrost system clears ice buildup in cold conditions. The unit runs at 38–48 dB and has a coefficient of performance of 5.5.

It connects with a universal adapter kit and is managed from a control panel. It fits most above-ground pools, including Intex and Bestway pools. Choose the size to match your pool's capacity, since an undersized unit may take much longer to heat or may not reach the desired temperature. To maintain it, regularly clean the heat exchanger surface and air filter so dust, leaves or debris don't block heat dissipation and air intake.
