George,
I suspect you're not overheating your water at all. What happens is that the water in your heater expands as it is heated, and has to go somewhere. In fact, there was a service bulletin (76-TM-4) concerning this expansion pushing hot water back into the cold water system. Of course, this is even more pronounced if you start off with cold water in the water heater.
Usually there is some air in the water heater that can compress to accommodate this expansion. However, if you seldom drain your plumbing and water heater, it may have become "waterlogged" as they used to say about well tanks before they had captive air bladders.
Try completely draining your water heater, and refill it. Another fix might be to add an expansion chamber of pipe fittings (only a cupful is needed) on the outlet side of the water heater, AFTER any check valves. HTH.
