3 expert-curated picks ranked by performance, value, and long-term reliability
Rheem is the largest residential water heater brand in the US, with the broadest product range across gas tanks, electric tanks, gas tankless, electric tankless, and heat-pump hybrid categories. This page covers the Rheem lineup with picks for the most-common buying scenarios.
Rheem's brand family includes Rheem itself (the main residential line), Ruud (commercial-leaning sister brand sold through plumbing supply houses), Richmond (Home Depot value tier), Marathon (lifetime-warranty polybuthylene electric), and Takagi (Japanese tankless acquired in 2009).
40K BTU, 87-gallon FHR, UEF 0.64, 12-year warranty. EcoNet WiFi available on premium sub-models. The most-installed residential gas tank in the US. About $799 unit, $1,650 installed.
Two 4500W elements, UEF 0.93, 12-year warranty, EcoNet WiFi. About $749 unit, $1,300 installed.
Polybuthylene tank cannot rust. Lifetime tank warranty. The 30+ year ownership value pick. About $1,899 unit, $2,500 installed.
UEF 3.55. $13/month operating cost (vs $48 for standard electric). Federal + utility rebates often net cost-neutral install. About $1,799 unit, $2,800 installed before rebates.
9.5 GPM rated, 199K BTU condensing, UEF 0.93, 12-year heat-exchanger warranty. Rheem's national plumber service network. About $3,500 installed.
Entry-tier Rheem at 40K BTU, 6-year warranty, UEF 0.58. Right for rentals and vacation homes. About $549 unit, $1,400 installed.
Rheem warranties stand whether the unit is DIY-installed or professionally installed — unusual versus Bradford White (which requires pro install for warranty). Performance Platinum tier: 12 years on tank and parts. Performance: 6 years. Fury entry tier: 6 years. Marathon: lifetime tank, 6-year parts. ProTerra: 10-year tank, 10-year compressor.
Rheem (Home Depot channel) vs A.O. Smith (Lowe's channel): functionally equivalent engineering at comparable warranty tiers. Choice usually depends on which big-box channel is convenient.
Rheem vs Bradford White (wholesale-only): Bradford White carries heavier construction and ICON thermopile gas control (operates through power outages) but shorter warranty (6-year vs Rheem's 12-year on Platinum tier). Choice depends on whether you DIY (Rheem) or use a plumber and want what the trade installs in their own homes (Bradford White).
Rheem has the most extensive US residential water heater service network — any plumber can service a Rheem unit, parts are available at any Home Depot pro counter, and Rheem-trained tankless specialists exist in every major metro. For service-availability priority, Rheem is the safer choice over smaller-brand alternatives.
