Kenmore 50 gal model

While reviewing the specs and features of the 50-gal models from Kenmore, it is important to say that there are several advanced models with the outstanding features.

Also, only three models are Energy Star compliant, which means that their energy efficiency is 0.68 or higher, mainly due to the advanced technology. These models are the power vent model 33136, model 33704 and model 33264 that comes with the pressurized air intake system.

The Kenmore 33136 is the power vent model that does not require a chimney, but uses the vent pipes up to 120 feet long, and terminates outside through the wall or roof. This model has also very high first hour rating of 96 gallons.

Model 33264 is coming from the Kenmore Elite series and is one of the latest designs from Kenmore and among the most advanced heaters mainly thanks to its patented air intake system that saves the energy. The LCD display screen makes this unit convenient to use, while the powered anode rod protects the metal tank and also reduces the service and maintenance time. From the high efficient water heaters this one has the longest warranty of 12 years.

The Kenmore 33704 is the atmospheric vent unit that is equipped with the flue damper that keeps the heat longer inside the tank, so more heat can be transferred to the water. Other great features include the self-cleaning RotoSwirl inlet tube and the intelligent gas valve as they improve the performance, accuracy and make the unit convenient to use.

Kenmore 50-gallon gas water heaters can be purchased only at the Sears store, or online, and the price is in the range from $400 to $1100.
