Kenmore gas water heater

As one of the most popular sizes, Kenmore 40-gal gas water heaters is also one of the largest groups.

Within this group of 40-gal hot water heaters, three models are unique, also Energy Star compliant, mainly due to its advanced engineering. Model 33135 is the power vent model that uses the electric blower and vent pipes up to 120 feet in length, of the flue gas exhaust, either through the wall or roof and without using the chimney. It also uses the advanced ignition and self-diagnostic system for better efficiency and convenient use. This unit has a high gas input of 50,000 Btus and First Hour Rating of 90 gallons.

The Kenmore 33262 Elite model is another Energy Star model that utilizes a patented air intake system for the enhanced efficiency. It also has the LCD control screen for easy water temperature adjustments and diagnostics. As opposed to other models, this model is equipped with the powered anode that protects the metal storage tank from corrosion but does not deteriorate over time as non-powered sacrificial anodes. The unit doesn't utilize the standard pilot light, but the advanced electronic ignition.

Kenmore 33702 is another great model that is equipped with the intelligent electronic gas valve system for easy troubleshooting through its diagnostic system. The flue damper keeps the heat energy longer inside the system and that increases the efficiency of the water heater.

You can buy Kenmore 40-gallon gas water heaters only at the Sears store and the price is in the range from $300 to $1000.
