About Envirotemp Water Heaters
Envirotemp is a Lowe's brand built by American Water Heater Company, the A.O. Smith subsidiary in Johnson City, Tennessee. Older units carry AQUAMATIC branding on the plate. The tank is the same American unit sold under several other names, which resolves most Envirotemp questions before they start.
The range is gas and electric residential tanks in common sizes, glass lined with an anode rod, atmospheric venting on the gas models. Some legacy series were sold only under this badge and American never published separate dimensions for them, so those figures are genuinely unavailable rather than simply hard to find. Natural gas and propane versions are different units, and the full model suffix matters when ordering parts.
The serial is the American format: the two digit year, then the production week, then the sequence, so 0912123456 is week 12 of 2009, sometimes with a plant letter attached. For parts, find the equivalent American or U.S. Craftmaster model of the same year, capacity, and fuel type, and order against that number.
Where to find the serial
Envirotemp water heaters are built by American Water Heater Company and use the AQUAMATIC serial system. The rating plate is on the upper third of the tank, with the serial in a black box labeled SER NO. or SERIAL.
What the serial actually looks like
Why the age is worth knowing
Envirotemp is a value-tier brand with typical 6-year tank warranties. These tanks are common in builder-installed new construction and rental properties, where the 6-year warranty matches the typical first-replacement cycle. After year 10 these are essentially end-of-life.
Quick answers for this brand
What does AQUAMATIC mean on my Envirotemp?
AQUAMATIC is the brand line used by American Water Heater Company for Envirotemp and several house-brand value tanks. It refers to the standard atmospheric gas burner with automatic ignition. The serial format inherits from American Water Heater's standard YYWW system.
Is Envirotemp the same as American Water Heater?
Envirotemp is one of American Water Heater Company's value brand names, sharing the Johnson City, Tennessee plant with American, Craftmaster, and various house brands. The tanks and warranty handling are similar across these names.
Where do I get parts for an Envirotemp?
Generic plumbing parts work fine. For brand-specific parts (gas valve, burner assembly), order through a plumbing supply that handles American Water Heater products. Most parts are interchangeable across the AWH family of brands.
