My old water heater (kenmore) finally went out. It was a 1985 that was in service for 24 years. I naturally purchased a new Kenmore 50 Gal water heater. It was easy to install, and I had hot water within 15 minutes of the gas being lit.
With the 2 inches of insulation, I will not have to wrap an insulation blanket around it, making it even easier to install!
