I bought a Reliance 40gal NORT970 heater in 1996. It was still working as of yesterday. But it developed a leak recently, and had to be removed. We sell Reliance where I work, and we don't get many complaints or returns. I plan to buy another Reliance heater.

After 31 years of use, I just replaced my Reliance 40 gal Model 501 gas water heater. It was still working fine but I noticed a small amount of water under the heater and I felt that a new heater would provide hotter water. The original heater had a 3 year warranty and sold for $178! Reliance made an incredible product... I hope the new one that replaced it is half as good.

June 8, 1991 purchased & installed a Reliance 501 natural gas hot water heater. Model #5-40-NORT6-F (manufactured 1988). Sad to have to replace it now TWENTY-SIX (26) years later. This Ashland, TN company ranks right up there with Scotch Tape, McDonalds & Kleenex & Rheem.

My current Reliance water heater is less than 50 days old and is very efficient at heating the water I use and maintaining it. I'm very pleased as is my family with its performance thus far. I selected it from several available and it met what I was seeking. As I have owned this brand in the past I knew it would meet my expectations. Reliance water heaters perform well over long periods of time. They are quality built and easy to adjust settings. They are also good for the pocket making them a great value. They came in quick order. The installers were very courteous and were very careful to remove the old one with the new without disturbing the area or making a mess throughout the process. It was not a lengthy time so my day was not overly disturbed. They arrived at the time that was scheduled which I appreciated.

The water heater works great. It has good hot water and good pressure. I am happy with it. It is a good brand. The water heater was in my home when I bought it, and I would buy another one if I had to replace the old one. I would suggest it to friends and family if they needed one.
