My State Censible 510E 50 gallon water heater (shows Model # PRV 50 NORT6 F) was made in 1991 and has never had any maintenance done to it. It seems to work perfectly, and I keep the water temperature at the lowest setting. I see that Obama proposed a Homestar pragram yesterday designed to give 50% off of energy saving home upgrades, which specifically included water heaters. So I'm thinking that my tank has already lasted longer than it should (is that true?), and is probably not energy efficient, but I donlt know that for sure. The tank has no blanket, but feels cold to the touch. The yellow Energy sticker says it had an annual estimated cost of $166 based on a rate at that time of .6054/therm. How does that compare to what I am likely paying per year now, and what savings might I expect in buying a new, high quality, energy efficient model? Keep in mind that I keep the temperature setting at the lowest level currently (does that really save much?). I guess I'm thinking that this unit probably wont last much longer anyway, and if this 50% rebate goes through, combined with the extra efficiency that I might (?????) get, buying a new unit might pay for itself in a few years. I know absolutely nothing about water heaters, and would be very interested in your insight. Thanks!

The purpose of this site is to help people make better choices and to teach them how to practice maintenance. Your tank is indeed quite elderly. What I always tell everybody who asks this question is, go to The Basics section, click on Know-How, and do the external inspection. If that looks good, pull the anode. If there is still some metal left on it, then putting in a new anode and possibly a flush kit could give the heater many more years of service. There are reasons why you might consider that. You might get 50 percent off the heater, but you're not going to get 50 percent off the installation cost (unless you do it yourself), so it could cost you a lot more up front than what you'll save in energy costs for a long time. Also heaters of this decade have had a lot of problems with FVIR systems. The Tank is full of posts from people talking about that. There is evidence the makers are starting to engineer past these problems, though, so that may clear up. Bradford White has a good system, but they're only sold through plumbers. If you do decide to buy new, then read the rest of The Basics so you can make an informed choice and know how to service the next heater so that it can become the last you ever buy. My own has been serviced regularly and is not 29 years old. How bout that?  Randy Schuyler
