FibroPool FH255 Pool Heat Pump vs AQUASTRONG HEX018 Pool Heat Pump

Buy the FibroPool FH255 for a large pool: 55,000 BTU covers in-ground pools up to 10,000 gallons and above-ground pools up to 21 ft round or 15 x 30 ft oval. Buy the HEX018 for a small pool or spa where a 120V outlet is all you have; its 18,000 BTU suits roughly 5,000 to 6,500 gallons. The FibroPool has a titanium heat exchanger, a weatherproof enamel-coated steel case and a 4.8 rating from 49 owners; the HEX018 has more reviews (4.5 from 125) and adds cooling down to 59 F. Owners of the FibroPool report quiet running and about a degree an hour of heat gain, but one reported case rust on a salt pool.

• Choose the FibroPool FH255 if you have a pool up to 10,000 gallons, a 240V circuit, and want the higher output and titanium exchanger.
• Choose the HEX018 if your pool is around 5,000 to 6,500 gallons, you only have 120V power, and you want cooling as well as heating.
