FibroPool FH255 Pool Heat Pump vs Pentair GulfStream HE 110-R-A Heat Pump

Buy the FibroPool FH255 for above-ground pools and small in-ground pools up to 10,000 gallons; it is a 55,000 BTU unit that also cools water, which the Pentair does not. Buy the Pentair GulfStream HE 110-R-A for larger in-ground pools that need roughly twice the heating capacity, a scroll compressor and a 7-year parts warranty. Owners of the FibroPool report quiet running, about a degree an hour of heat gain and reliable service over several years, but one owner saw the steel case rust on a salt pool. Pentair's GulfStream line has a longer warranty and more capacity, but this model is heat-only and some units arrived with a leaking coil.

• Choose the FibroPool FH255 if you have an above-ground pool or an in-ground pool up to 10,000 gallons and want heating plus cooling from a 240V unit.
• Choose the Pentair GulfStream HE 110-R-A if you have a larger in-ground pool, need about 110,000 BTU, and value the 7-year parts and 2-year labor warranty.
