The tank is constructed from heavy-gauge steel and coated with porcelain-like glass lining. This glass lining protects the steel from direct contact with water, preventing rust. However, because glass can develop microscopic cracks over time, the unit includes a sacrificial magnesium anode rod. The anode rod corrodes in place of the tank, and periodic inspection/replacement is critical for longevity.
Key detail: The 5V40-7 uses a single anode rod integrated into the hot water outlet nipple.

Verdict: The 5V40-7 is an economy unit. It is not the most efficient or durable, but it is one of the most affordable 40-gallon natural gas tanks on the market (typically $450–$550 at Menards). richmond 5v40-7 water heater specs
The 5V40-7 is an atmospheric vent (also called natural draft or Type B vent). It relies on natural buoyancy to expel combustion gases. Vented gases can reach 350°F–450°F.
Warning: Do not install this in a tightly sealed home without adequate combustion air. The unit requires 50 cubic feet of air per 1,000 BTU—meaning at least a 1,900 cubic foot room (or louvered door to a larger space).
When it comes to reliable, budget-friendly residential water heating, the Richmond brand—exclusively sold at Menards—has long been a staple for homeowners and contractors alike. Among their most popular models is the Richmond 5V40-7. If you are searching for the precise dimensions, recovery rate, energy efficiency, or installation requirements for this unit, you have come to the right place. The tank is constructed from heavy-gauge steel and
This article provides an exhaustive deep dive into the Richmond 5V40-7 water heater specs, including performance data, physical measurements, warranty information, and common replacement considerations.
The Richmond 5V40-7 features a Honeywell electronic gas control valve with a piezo spark igniter. Unlike old standing pilot models, this uses a thermocouple and thermopile to generate millivolts to hold the pilot flame.
Thermostat settings:
Recommended setting: "Hot" or low "A" to balance safety and efficiency.
With a 38,000 BTU/hr natural gas burner, the 5V40-7 is considered a standard-efficiency unit. Its recovery rate is 35.1 gallons per hour (GPH) with a 90°F temperature rise (e.g., raising groundwater from 50°F to 140°F).
For practical use, the First Hour Rating (FHR) of 67 gallons is more important. FHR measures how much hot water the tank can deliver in the first hour of use—accounting for stored hot water plus recovery during that hour. At 67 gallons, this unit can handle: Warning: Do not install this in a tightly
With a 38,000 BTU burner, the Richmond 5V40-7 can raise 38.8 gallons of water by 90°F per hour. The First Hour Rating (67 gallons) means you can take approximately two back-to-back showers (using 15-20 gallons each) plus run a dishwasher before the tank runs cold—adequate for most small to medium families.
