Replace a working, old water heater?
My electric water heater (AO Smith) is original to the house, which was built in 1987. It works fine and I have never done anything to it execept drain it twice (to move it).
Since it is 24 years old, should I replace it now to avoid an emergency repair that is probably coming?
I will be replacing it with just a standard, no frills electric like the GEs at Home Depot. Are the new water heaters that much more efficient that I would notice the difference in my electric bill?
