Best Brand Of Water Heater

3 expert-curated picks ranked by performance, value, and long-term reliability

Choosing the right brand of water heater depends on your fuel source, install scenario, and where you shop. This list provides honest brand-by-brand assessment with the specific scenarios where each excels.

Brand rankings by buyer scenario

For DIY mid-tier gas tank — Rheem

The volume leader. Performance Platinum (12-year warranty) at Home Depot. Strongest DIY-friendly brand with longest mainstream warranty. The default first-shop for most US homeowners.

For plumber-installed primary residence — Bradford White

Wholesale-only — not at any big-box. Vitraglas tank lining, ICON gas control (runs through power outages), heavier construction. The water heater plumbers buy for their own homes.

For Lowe's shoppers — A.O. Smith

Lowe's-dominant brand. Signature Premier (12-year warranty) is the equivalent of Rheem Performance Platinum. Voltex heat-pump line is the operating-cost leader.

For lifetime electric — Rheem Marathon

Polybuthylene tank cannot rust. Lifetime tank warranty.

For heat-pump (lowest operating cost) — Rheem ProTerra

UEF 3.55. $13/month operating cost. Federal + utility rebates often net cost-neutral install vs standard electric.

For gas tankless — Rinnai or Navien

Rinnai has the densest US service network. Navien has built-in recirculation (ComfortFlow) that eliminates cold-water sandwich.

For electric tankless — EcoSmart or Stiebel Eltron

EcoSmart for lifetime warranty (heat exchanger + electronics). Stiebel Eltron for premium German engineering.

For RV / outdoor — Suburban / Furrion / Eccotemp

Specialty brands for niche applications.

Brand ownership map

Important context: most US water heater brands belong to one of three corporate families.

Rheem family (Paloma Industries)

Rheem, Ruud (plumbing supply channel), Richmond (Home Depot value), Marathon (lifetime electric), Takagi (tankless).

A.O. Smith family

A.O. Smith, State, American, Whirlpool (license), U.S. Craftmaster, Reliance, GE-branded (license).

Independent — Bradford White

Privately held since 1881. Wholesale-only distribution. The only major US brand outside the Rheem/A.O. Smith duopoly with meaningful market share.

Specialty independents

Rinnai (Japanese), Navien (Korean), Bosch (German), Stiebel Eltron (German), Noritz (Japanese), Takagi (Japanese, Rheem-owned).
