  • The filed efficiency, capacity and tank size of both models, side by side below.
  • Both are ENERGY STAR certified, which requires a manufacturer warranty of at least six years; the actual term for each model is not published.
  • Time on the market, as filed with ENERGY STAR: the A. O. SMITH HPTV-80 2** since 2023-07-10, the AMERICAN HPTS-80 2** since 2022-06-06. A sale date, not a lifespan.
