Our take on the GG40T08BXR 40 gallon tall, natural gas, atmospheric

The GE GG40T08BXR is a 40-gallon tall natural gas water heater with a 40,000 BTU atmospheric burner. The tall, narrow tank fits garages, closets and utility rooms where floor space is tight, and the atmospheric vent works with standard metal flue venting. It is a conventional tank heater, so it competes on recovery speed and simple installation rather than the efficiency of a condensing or heat pump unit. Owners rate it well overall, and the common complaints are about pilot and thermocouple issues and the maintenance a tank heater needs.

About the GG40T08BXR 40 gallon tall, natural gas, atmospheric

The GE GG40T08BXR is a 40-gallon tall natural gas water heater for residential hot water. It has a 40,000 BTU burner and an atmospheric vent, and it connects with standard water and gas connections.

The tall cabinet takes up less floor space. That suits garages, utility rooms, closets and other spaces with limited room. The atmospheric vent works with traditional vented installations, including replacement and new home installations.

The insulated tank helps reduce standby heat loss. The burner reheats water quickly after demand increases. The tank holds enough for showers, dishwashing, laundry and cooking in homes with two to five people. Safety and diagnostic features are included.

Questions and answers

Is 40 gallons enough for a family?
For a household of about three to four people it covers showers, laundry and dishes. Larger families or homes with several simultaneous hot-water uses may want a bigger tank or a higher-BTU model.
What venting does it need?
It uses an atmospheric vent, so it connects to a standard metal flue that vents upward. It is not a direct-vent or power-vent unit.
How does it compare with a high-efficiency heater?
A condensing or heat pump unit uses less gas, but costs more and often needs different venting and drainage. This model is the simpler drop-in choice for an existing atmospheric setup.
How much space does the tall tank need?
The tall design trades width for height, so check ceiling and flue clearance above the unit as well as the floor footprint.
Does it work with natural gas only?
Yes, this model is built for natural gas. A propane version is a separate model and the two are not interchangeable.
