Where does the wiring go on an electric water heater?
Although you won’t need to deal with the thermostats or heating elements during a simple replacement of an electric water heater, it’s helpful to know that electric water heaters also include inner wiring that runs from the wire connection box down along the side of the tank to two different heating elements, each controlled by its own thermostat.
Why does my water heater run all the time?
If you’re lucky, it is simply running all the time because one element has died and the other works overtime to keep the water warm. Until the second element dies. Then it is all cold.

How does an electric water heater get hot?
Most electric water heaters use two heating elements (one near the top of the tank and one at the bottom). The lower element does most of the heating because water gets hot via conventional currents. This means that cold water comes to the bottom; when it gets hot, this liquid rises to the top.

But that’s what can happen if your water heater has a shorted heating element or a broken thermostat. A thermostat that’s stuck in the “on” position will cause the heating element to stay on constantly, overheating the water in the tank. Or, if the element breaks, it can make contact with metal inside the water heater, creating a short circuit.
How can I tell if my water heater is too hot?
Be sure to check both sides of the heating element. If you don’t measure continuity from the element to the cabinet, check the resistance through the element to see if it’s okay. Touch one meter probe to each of the element leads. A good heating element will measure about 13 ohms of resistance.
Why does my hot water heater run out during a shower?
If your unit is not undersized, or it suddenly produces less hot water than it used to, one or both of its heating elements may have failed. A constant supply of lukewarm water during a shower is indicative of a defective upper heating element. Hot water that runs out quickly during a shower is indicative of a defective lower heating element.
