Richmond Essential 40-Gallon Natural Gas Water Heater

The Richmond Essential 40-Gallon Natural Gas is the smaller-capacity sibling of the Richmond Essential 50-gallon — Rheem's value-tier 40-gallon gas tank at Home Depot. Built by Rheem with the Richmond brand for the value/budget segment.

Specs: 40,000 BTU input, UEF 0.58, 71-gallon first-hour rating, 6-year tank and 6-year parts warranty. Atmospheric vent through B-vent. Standard residential gas control with electronic ignition. Magnesium anode rod, polyurethane foam insulation. Same physical dimensions as Rheem Performance 40-gallon — drops into the same closet positions.

The 40-gallon capacity is right for 1–2 person households with sequential demand or installs where closet height (52" tall typical for 40-gallon) prevents installing a 50-gallon (60" typical). For 3+ person households, the 50-gallon Richmond Essential or upgrade to Rheem Performance Platinum (12-year warranty) is usually the better choice.

Right buyer: budget-conscious 40-gallon gas tank replacement in a small household. Rentals, vacation homes, 1-2 person primary residences with 5-7 year ownership horizons. About $399 at Home Depot, $1,100 installed. The Richmond brand exists specifically to offer a value-tier option at Home Depot for buyers not ready to pay for Performance Platinum's 12-year warranty.
