This is a 120V above-ground pool heat pump rated at 18,000 BTU, with a dual-mode system that heats water to 104°F or cools it to 59°F. Its headline figure is a COP of 5.5, which the maker says cuts energy use about 70% against traditional electric heaters and 40% against natural gas. It runs at a claimed 38–48 dB with automatic defrost, and the universal adapter kit is meant for a DIY hookup in about 10 minutes. Owners rate it highly for quiet running, easy setup and steady temperature control, but several say it struggles in cold weather and needs a pool cover to heat efficiently.
