      The A.O. Smith ProLine 40‑Gallon Short Electric Water Heater delivers dependable hot water performance in a compact, space‑efficient design ideal for tight basements, closets, and low‑clearance mechanical rooms.

      Built for long service life, this model features dual 4.5 kW heating elements that provide fast, consistent recovery to meet everyday residential hot water demands. The tank is protected by A.O. Smith’s durable glass‑lined enamel coating, engineered to resist corrosion and extend longevity, while a robust magnesium anode rod adds an extra layer of defense against tank degradation.
