GE Profile GeoSpring Smart Hybrid Heat Pump Water Heater, 80 gal
Installed price varies more between contractors and local labor markets than between brands. Get more than one quote, especially for a heat pump water heater that needs electrical work.
80-gallon version of the same Profile GeoSpring Smart Hybrid platform as the 50-gallon model -- same UEF 4.50, larger first-hour rating.
Our take
Same platform, same caveat as the 50-gallon: a genuinely strong spec sheet (this and the 50-gallon share the highest UEF in the catalogue) with no independent owner track record behind it yet. Certified July 2025, so treat it the way you'd treat any first-model-year appliance -- promising numbers, unproven in the field.
Best for
Larger households wanting the most efficient HPWH on paper, from the same dealer-network channel as the 50-gallon.
Watch out for
No owner reliability data yet. Tall tank (57.2 in) -- measure ceiling clearance before ordering, same as any 80-gallon HPWH.
Compare against
GE Profile GeoSpring Smart Hybrid Heat Pump Water Heater, 50 gal
GE's flagship heat pump water heater, relaunched under the Profile line with FlexCAPACITY mixing and Wi-Fi control. ENERGY STAR-certified at UEF 4.50 -- the highest efficiency figure in this catalogue at any size.
Rheem ProTerra Hybrid Heat Pump Water Heater, 50 gal
The default heat pump water heater for most US households: 50 gallons, UEF 3.75, widely stocked and widely serviced.
Rheem ProTerra Hybrid Heat Pump Water Heater, 80 gal
80-gallon version of the ProTerra, UEF 4.0 — the highest efficiency in the mainstream heat pump water heater market.
A. O. Smith ProLine XE Voltex AL (HPTS-66) Heat Pump Water Heater, 66 gal
66-gallon heat pump water heater with a UEF of 4.02 -- among the highest in our water heater set, just behind GE's Profile GeoSpring Smart Hybrid at 4.50. Sold under A. O. Smith's 'ProLine XE Voltex AL / Smart Hybrid' line — a different, retail-exclusive 'Signature Series' name is used for a different model-number family at Lowe's, so don't cross-shop the names.
Before you buy this
Ask for the first-hour rating, not just tank size, and check it against your household's simultaneous demand — showers and laundry at the same time — rather than headcount alone. If it's a heat pump water heater, confirm the room has enough air volume (or a duct kit) that it won't spend winter on resistance backup, and that there's a real route for condensate, not just a nearby floor drain. Confirm the panel has spare 240V capacity. And if you're removing a gas unit that shared a flue with a furnace, ask what happens to that flue once your water heater's draft is gone — an orphaned flue can backdraft.
