Yesterday while running hot water it was very hot --almost boiling. I
have a 40 gal. electric water heater. Does this mean a stuck thermostat
and how do I change it?

Did you ever watch the TV show Mythbusters? They contested a myth that a
hot water tank could explode with so much force that it would launch like
a rocket through several floors and out the roof. They disabled the
thermostat and safety relief pressure valve and at about 320 degrees F
inside, the tank launched as expected. And this was using only the
heating elements in the heater, no external heat source.

My point is; If you don't know how to change a thermostat you should
probably seek local professional help and not trust the advice from the
lunatics in this news group.
