I have a brand new Bradford 40 gallon single element water heater. I installed the heater exactly as I should have, and filled it all the way up with water. I then turned the breaker on. I waited and waited, but it never heated the water at all. I tested the element and thermostat, and it had power and the correct amount. What can I do next? I have read something about the thermostat calibration.
If the element has power to it, then it should be heating. But you can check the temperature setting (most are set too low from the factory, IMO) and the reset button on the thermostat.
