Which is better for an above-ground pool?

The FibroPool FH255. It is rated for above-ground pools up to 21 feet round or 15 x 30 oval, and it runs on a 12A circuit. The Hayward HeatPro is sized and plumbed for in-ground pools.

Is the Hayward worth the extra money?

Only if your pool is large. At $6,999.00 at Amazon as of November 7, 2026, it costs about $5,200 more than the FibroPool at $1,799.99 at FibroPool. That buys 140,000 BTU instead of 55,000, which matters on big in-ground pools and not on pools under 10,000 gallons.

Both use titanium-style heat pump construction, and neither maker publishes a service life. The FibroPool's titanium exchanger resists saltwater corrosion, but one buyer reported case rust on a salt pool. Hayward's brand has broader parts availability for long-term repair.

Can the FibroPool heat a 15,000 gallon pool?

No, not well. FibroPool rates it for in-ground pools up to 10,000 gallons. A 15,000 gallon pool needs a larger unit such as the Hayward HeatPro.

What electrical setup does each need?

The FibroPool needs a 240V, 12A circuit on 12 gauge wire. The Hayward needs 230V at 41 kW with a 70A maximum breaker, so it usually requires a dedicated subpanel.

Which heats water faster?

The Hayward, by a wide margin, because it outputs 140,000 BTU against 55,000. FibroPool buyers report roughly a degree an hour on their sized pools; the Hayward will raise a large pool faster.
