I have a hot water heater that uses a small screw to set the temperature of
the water. I have the unit set at about 120-135 degrees, but the water
coming from the unit is more than 150. Also the breaker on the water heater
itself is kicking off each day and I have to reset it to get hot water. Any
ideas of why this is happening? What should I do?
The thermostat is defective (sticking?).
One of the elements has an internal fault to the element sheath.
This can allow current to flow even though the thermostat opens
(one side of) the circuit.
It is probably not a good idea to have the water heater on if the breaker
keeps going off. Unless you have a defective breaker, it is trying to tell
How many watts is the heater? How many amps is the breaker? Did it just
start doing this?
If you know someone with an ampmeter (or want to spend $30 for a really fun
tool) it would be nice to measure the amperage.
