How a Water Heater Element Works

When it comes to electric water heaters, water heater elements and electric wiring are the main problems. If you have hot water that runs out quickly your lower heater element may be at fault. But if your water heater takes long to recover after using lots of water then your upper element may be the issue.

When electricity passes through the water heater element it meets some resistance. This resistance creates instant heat just like rubbing your hands against each other. Your wattage will, therefore, determine the amount of heat produced.

It’s important to test your element to know whether it works well or not. To do this you just need a multimeter and a screwdriver. To replace it, you need a screwdriver, a wrench, and a garden hose.

How to Replace a Water Heater Element without Draining Tank

To safely do this, you first need to shut off the water supply at the water heater. Make sure no faucet in the house is turned on. This is to prevent air from getting into the tank. Next, put a bucket under the water heater drain and then open the drain valve to allow the pressure to come off the tank.

Once you are done, remove the old element and install a new one. If the water valve does not shut well or you have dripping faucets, you may get a little wet. If the process goes on well you’ll only lose 2 cups of water.
