Pentair GulfStream HE150-RA Heat Pump vs Pentair GulfStream HE 110-R-A Heat Pump

Both are heat-only Pentair GulfStream heat pumps with titanium exchangers and scroll compressors, so the real split is capacity. The HE150-RA (142K BTU, or 138K under current 80/80/80 testing) moves roughly 30% more heat than the HE 110-R-A, which suits larger pools and faster recovery in cool weather. The HE 110-R-A is the better fit for smaller pools and has a published COP of 6.1, a digital diagnostic LCD and a 7-year parts / 2-year labor warranty. Owners of the smaller unit report fast shipping and quick factory service, but also occasional error codes and a leaking coil after install.

• Choose the GulfStream HE150-RA if your pool is large or you swim in shoulder seasons and need the extra heating capacity.
• Choose the GulfStream HE 110-R-A if your pool is modest, your electrical service is standard 208/230V single-phase, and you want a documented COP and a clear warranty split.
