Q:I have put a new pressure valve and replaced both thermostat

If it is not overheating due to a stuck thermostat or bad heating element and you changed the TP valve then it is possible you have a problem with thermal expansion. When water is heated it expands and the more it is heated the more volume it will need to expand. Since the water heater and the piping are not designed to expand the water only has one place to go (well two if count the faucet) and that is out the TP valve. This problem is not uncommon and the solution is to have an expansion tank installed on the hot water heater in the piping near the tank.
