The AQUASTRONG HEX018 is a dual-mode heat pump for above-ground pools: it heats water from 59 to 104°F and cools it from 59 to 83°F. It runs on a standard 120V outlet, which most pool heat pumps do not, so it suits pools without a 240V line. A rated 5.5 COP (the listing also claims 6.5) means it moves several units of heat per unit of electricity, far cheaper to run than a resistive electric heater. Owners rate it 4.5 out of 5 and most praise quiet operation, easy setup and efficiency; a minority of low ratings report units that did not heat as expected.

The HEX018 is an 18,000 BTU pool heat pump for pools up to 6,500 gallons. It runs on 120V and works in two modes. It heats pool water to between 59 and 104°F, or cools it to between 59 and 83°F. The maker says this can extend the swimming season by up to 6 months.
A thermostat holds the water temperature within ±2°F. Operating noise is 38 to 48 dB. An automatic defrost system clears ice buildup without manual steps.
It comes with 1.25" hose adapters and 1.5" conversion kits, and installation takes under 10 minutes. The control panel supports multiple smart control modes. A 3-year warranty is included.
