The 30-Second Verdict
The water heater you buy at Home Depot is NOT the same as what your plumber installs from their supplier — even when both say "Rheem" or "GE" on the label. Big-box units (Lowes/Home Depot GE, Rheem, Whirlpool) are typically lower-spec versions with thinner steel, shorter anode rods, and 6-year warranties. Plumber-supplied brands (Bradford White, A.O. Smith ProLine) have heavier construction, magnesium anodes (better for FL hard water), and 8–10 year warranties standard. Big box wins on price ($400–$700 cheaper); pro brands win on FL hard-water lifespan (12–15 years vs 7–10).
