Gas Water Heater Basics
Most of our customers in Arizona have gas water heaters (63%); approximately 35% have electric water heater units. The remaining are hybrid-type units such as solar or thermal water heating. If you're a homeowner and you have a gas water heater, you should know the gas water heater basics like determining the age of your unit in case of the need for replacement.
Gas Water Heater Lifespan
Gas water heaters have a lifespan of about 8-12 years on average in Arizona. If you're having trouble with your gas water heater you might try to turn off the water and power to the unit. On a gas unit, set the burner to “pilot.” Connect a garden hose to the spigot at the base of the tank. With the other end of the hose pointed at your floor drain, carefully lift the tank's pressure-relief valve and turn on the tank's spigot; water should begin to flow.
What's The Age Of My Water Heater?
To figure how old your water heater is, first find the label on the water heater. You can easily determine the brand of your water heater. Water heater manufacturers document the month and year of manufacturing as part of the serial numbers on the water heater. Check to find the brand water heater you have. Then use the description to decode the serial number.
