Six tanks, scored out of 100 — gas, electric, and hybrid
A tank water heater is a ten-year decision you usually make in one bad morning. The cold shower concentrates the mind, the plumber is already quoting, and the size on the truck becomes the size in your basement. This page exists so that decision is made on numbers instead: every pick below is scored on the same published rubric — heating performance 30, efficiency 25, running cost 25, warranty and parts 20 — worked from manufacturer spec sheets and the DOE efficiency database. We do not test these heaters in a lab and we will not pretend otherwise; what we do is the math, in the open, and we show our work.
One thing the spec sheet will not tell you: the badge matters less than the channel. Rheem sells one line through Home Depot and another through plumbers. A. O. Smith sells Signature at Lowe’s and ProLine through contractors. Bradford White sells only through plumbers, full stop. The same brand name can hide two different tanks, so every pick below names its channel — because where you buy decides what your warranty claim looks like in year seven.

The picks, scored
Rheem Performance Platinum 50-Gallon Gas
88/100
The retail gas tank to beat. A 40,000 BTU burner recovers 40.4 gallons an hour, the self-cleaning dip tube fights the sediment that kills tanks early, and the 12-year warranty is double what most of this class offers — with three years of in-home labor behind it, which is the part that actually saves you money when something fails. Sold through Home Depot, so parts and warranty swaps run through a store counter, not a supply-house phone tree.
- ModelXG50T12HE40U0
- First-hour rating77 gal
- Recovery (90°F rise)40.4 gal/hr
- UEF0.65
- Warranty12 yr tank & parts
Rheem ProTerra 50-Gallon Hybrid
86/100
A heat pump on top of a tank: it moves heat out of the room air instead of making heat with a wire, which is how a water heater posts a 3.88 UEF — roughly four times the efficiency of the electric tank it replaces. LeakGuard leak detection with an automatic shutoff is the feature owners actually write home about. The honest trade-offs: it wants about 700 cubic feet of air (or ducting), it cools and dries the room it sits in, and its 67-gallon first hour is a step behind the big gas burners. Sold through Home Depot and plumbing channels.
- ModelXE50T10HS45U1
- First-hour rating67 gal
- Recovery (90°F rise)27 gal/hr
- UEF3.88
- Warranty10 yr tank & parts
Rheem Professional Classic 50-Gallon Power Vent
84/100
When the old tank vented through a chimney you no longer have — or the heater lives in a closet or finished basement — a power vent is the swap that works: a blower pushes exhaust through PVC, with vent runs up to 100-plus equivalent feet. This is Rheem’s pro-channel version: 42,000 BTU, the best recovery rate in this lineup, and a 0.68 UEF that leads the gas picks. The catch is the warranty: six years, half the Platinum’s, because the pro channel assumes a contractor relationship instead of a store warranty. Rheem also does not list Amazon as an authorized seller for its pro line — buy through a seller you can verify.
- ModelPROG50-42N RH67 PV
- First-hour rating78 gal
- Recovery (90°F rise)42.4 gal/hr
- UEF0.68
- Warranty6 yr tank & parts

Bradford White Defender 50-Gallon Gas
82/100
The highest first-hour rating on this page — 89 gallons — from a 40,000 BTU burner and the Hydrojet dip tube that keeps sediment in suspension so it leaves with the water instead of baking onto the tank floor. The ICON gas control runs on the pilot’s own thermopile, so this tank keeps making hot water through a power outage. The trade-off is the whole business model: Bradford White sells only through licensed plumbers. There is no store shelf and no Amazon listing from the manufacturer, so the price you pay is an installed price — get it in writing, and compare it against the retail picks above with labor included on both sides.
- ModelRG250T6N
- First-hour rating89 gal
- Recovery (90°F rise)43 gal/hr
- Efficiency0.63 EF (pre-UEF rating)
- Warranty6 yr tank & parts
A. O. Smith Voltex 50-Gallon Hybrid
80/100
The other hybrid worth pricing. A 3.45 UEF trails the ProTerra but still cuts an electric water-heating bill by roughly two-thirds, and A. O. Smith matches the 10-year warranty. It is the pick when the Rheem is out of stock or your installer is an A. O. Smith house — the two are close enough that the channel and the quote should decide. Sold through plumbing wholesalers (A. O. Smith’s ProLine XE line), not the Lowe’s Signature shelf.
- ModelHPTU-50N
- First-hour rating66 gal
- Recovery (90°F rise)≈25 gal/hr
- UEF3.45
- Warranty10 yr tank & parts
Rheem Performance Platinum 50-Gallon Electric
78/100
No gas line, no vent, no desire to spend hybrid money: this is the honest electric pick. Two 5,500-watt stainless elements recover 25 gallons an hour, the first-hour rating matches the hybrids, and the 12-year warranty is the longest in this lineup. It scores last here for one reason only — running cost. Resistance heat is the most expensive way to make hot water per gallon, and over a 12-year life that gap is worth more than the purchase-price gap to a hybrid. If your electric rate is low or your draw is small, that math flips; the Sizing & Cost hub works it both ways.
- ModelXE50T12EC55U1
- First-hour rating68 gal
- Recovery (90°F rise)25 gal/hr
- Efficiency0.95 EF
- Warranty12 yr tank & parts

The deciding numbers, charted
First-hour rating is the only size number that matters — it is what your busiest hour actually draws. Here is the field, straight from the spec sheets:
First-hour rating per manufacturer spec sheets and the DOE efficiency database, checked 2026-11-09. A typical 4-person morning peak runs 55–70 gallons.
And the number that decides what the tank costs you every year after install day. For the hybrids, read UEF against the electrics, not the gas units — the scale changes because a heat pump moves heat instead of making it:
DOE-modeled annual energy cost at a 64 gal/day draw, national average fuel prices. Your rates move these numbers; the ranking rarely flips.
How the scoring works
Every score above comes from the same rubric published on How We Rate: heating performance (30) from first-hour rating and recovery against the size class; efficiency (25) from UEF; running cost (25) from DOE-modeled annual energy cost at a typical draw; warranty and parts (20) from tank/parts term, labor coverage, and how a claim actually gets fulfilled in that model’s sales channel. A concrete example: the Bradford White Defender posts the best first-hour number here and still lands at 82, because a 6-year warranty and an installed-only channel cost it points the spec sheet cannot win back. That is the rubric working as intended — the best tank on paper is not always the best tank to own.
Why there are no prices on this page
Water-heater prices swing by region, channel, and week — the same Rheem Platinum is one price at a Home Depot in Ohio and another in Oregon, and the Bradford White has no shelf price at all. Rather than print a number that is wrong by Friday, we print the numbers that do not move — first-hour rating, recovery, UEF, warranty — and send you to the seller for today’s price. Installed-cost ranges, which is where the real money is, live in the Sizing & Cost hub.
