Bradford White RG240S6N 40-Gallon Short Atmospheric Gas Water Heater

The Bradford White RG240S6N is the "short" or "low-boy" version of the popular RG240T6N — a 40-gallon natural gas atmospheric water heater designed for installations where standard tank height (52" tall) doesn't fit. The "S" suffix identifies the short configuration: roughly 47" tall × 22" diameter, versus the standard 52" × 20" of the regular RG240T6N.

The short configuration uses a wider, lower-profile tank with the same 40-gallon capacity. Trade-offs: requires more floor space (22" diameter vs 20"), can fit under low ceilings or counter-mounted utility room shelves that won't accommodate the standard model. Common in mobile home water heater compartments, basement crawlspace mountings, and certain garage installs where overhead clearance is limited.

Specs: identical to the RG240T6N — 40K BTU, UEF 0.62, 73-gallon FHR, 6-year warranty, ICON thermopile gas control (runs through power outages), Vitraglas tank lining. Same wholesale-only distribution (not at Home Depot or Lowe's). Plumber-installed price $1,750–$2,250.

Right buyer: any install where standard 52" tank height is the constraint, particularly mobile home and tight-space residential installations. The short configuration is genuinely useful when needed; for installs with adequate ceiling height, the standard RG240T6N is the better choice (slightly cheaper, smaller floor footprint).
