Are water heater elements Universal?
There are three types: screw in, bolt in and clamp in. They all have different wattage ratings and can work on either 120 or 240 voltage. Check your state and local codes before starting any project.
Each element has its own thermostat, and only one element runs at a time. The top element turns on first to start the warming process. Once the water in the top half of the tank reaches the set temperature, the top element turns off, and the bottom element turns on to heat the rest of the water.
