I have a 40 gallon A O Smith gas hot water heater that seems to over heat and then shut down. It turns of the pilot light and I can’t relight it until it cools down. The unit has been installed approximately 20 years ago. Is it just at the end of its life? If so how do Bradford White compare to A O Smith?
Thanks

| While you certainly got your money worth from your current heater and replacing it might not be such a bad idea. The problem as you describe with your current heater is the thermostat is defective. Replacing it will solve this problem.

Hello: I'm useless to you on cost, but your older heater has a high limit that resets. Modern thermostats have a one time fuseable link that melts if things overheat. If there is something in the way the old heater was installed that promotes overheating, or if the thermostat is not controlling temperature well, it's not a bad thing to make it safer. You might be able to replace the thermostat and anode, but at this point you may not be able to significantly extend the heater's life 
Yours, Larry
