Rheem ProTerra Hybrid Heat Pump Water Heater, 80 gal
Prices are the equipment only — the appliance, before install labour. Every product in this catalogue currently has at least one real, seller-observed equipment price (see the SKU verification and price observation notes on each product). Get contractor quotes for the install itself, especially for anything needing new electrical circuits or condensate drainage.
80-gallon version of the ProTerra, UEF 4.0 — the highest efficiency in the mainstream heat pump water heater market.
Our take
The larger tank does two things: it serves a bigger household, and it lets the heat pump do more of the work instead of falling back on resistance elements during heavy draws. That is why the 80-gallon posts a higher UEF than the 50. If you have the floor space and the ceiling height, sizing up is usually the better buy even for a moderate household.
Best for
Households of four or more, or any home planning to add a heat pump water heater alongside high-draw fixtures.
Watch out for
Tall. Measure your ceiling height including the top connections before ordering — this is the most common return reason.

Equipment price is not installed price. The listings above are what the hardware costs. Installation — labour, electrical, refrigerant lines, permits, removing the old system — is typically a similar amount again, and varies more between contractors than between brands. Where we have an installed figure it is labelled as such and comes from someone who actually installs.
Where the spec sheet and owners disagree
Sound Db — datasheet 49 vs reported 70dB(A)
The datasheet gives Sound level as 49dB(A). An owner reports measuring 70dB(A) in real installations — roughly 43% higher. We publish both figures and let you judge; the specification is not wrong so much as measured under conditions your installation will not reproduce.
What owners and installers report
Collected from trade forums, owner communities and video reviews. Every report links to the original. We synthesise and quote briefly — we don't republish other people's writing.
Every report below traces back to a single source. The sections are broken out by topic because that's how they read, but treat this as one data point, not independent corroboration across topics — a second source agreeing (or disagreeing) would change that.
Noise in real installations
What owners report hearing, versus the manufacturer's rated sound level. Rated figures are measured under controlled conditions that rarely match a real installation.
Multiple owners report Gen 5 ProTerra units running at 68–72 dB — far above the quoted figure and far above the ~49 dB owners report from Gen 4 units. Two warranty replacements did not resolve it, and Rheem ultimately offered only a sound isolation kit, stating the noise was within normal operating parameters.
“very loud high pitched compressor whine + loud fan. It's like a commercial walk-in refrigerator” — finePNW homeowner, 2024-02-29
Reported measurement: 70dB(A)

Warranty and manufacturer support
What actually happens when owners make a claim.
Warranty replacement did not resolve the noise complaint — the replacement units exhibited the same behaviour, and service technicians classified it as normal.

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.
