How do I replace a water heater heating element with a low watt density element?

Replacing a water heater heating element can be a daunting task, especially if you’re not familiar with electrical work. However, it’s a necessary maintenance task that can improve the efficiency and lifespan of your water heater. In this article, we will discuss how to replace a water heater heating element with a low watt density element, including the tools you’ll need and the steps to follow.

What is a Low Watt Density Element?

A low watt density element is a type of heating element that is designed to heat water more efficiently than a standard heating element. It has a larger surface area, which allows it to heat water more evenly and prevent scorching. This can help to extend the life of your water heater and reduce your energy bills.

Tools You’ll Need

Before you begin, you’ll need to gather the following tools:

• Screwdriver
• Socket wrench
• Multimeter
• Low watt density heating element
• Teflon tape
• Wire stripper
• Wire nuts

Steps to Replace a Water Heater Heating Element with a Low Watt Density Element

1. Turn Off the Power

Before you begin, turn off the power supply to your water heater. You can do this by switching off the circuit breaker or disconnecting the power supply at the main panel.

2. Drain the Water Heater

Next, you’ll need to drain the water heater. Connect a garden hose to the drain valve at the bottom of the tank and run the hose to a drain or outside. Open the valve and allow the water to drain out completely.

3. Remove the Old Heating Element

Once the water heater is empty, you can begin removing the old heating element. Use a socket wrench to remove the nuts that hold the heating element in place. Then, use a screwdriver to disconnect the wires from the element.

4. Install the Low Watt Density Element

Wrap Teflon tape around the threads of the new low watt density heating element. Then, insert the element into the tank and tighten the nuts with a socket wrench. Be careful not to overtighten, as this can damage the threads.

5. Connect the Wires

Next, connect the wires to the new heating element. Strip the ends of the wires and twist them together with wire nuts. Be sure to match the wire colors to ensure proper connections.

6. Test the Heating Element

Once the wiring is complete, use a multimeter to test the new heating element. Set the multimeter to the ohms setting and touch the probes to the terminals of the heating element. The reading should be within the range specified by the manufacturer.

7. Refill the Water Heater

Once the new heating element is installed and tested, you can refill the water heater. Close the drain valve and turn on the cold water supply. Allow the tank to fill completely before restoring power to the water heater.

Conclusion

Replacing a water heater heating element with a low watt density element can improve the efficiency and lifespan of your water heater. While the process may seem intimidating, it’s a relatively simple task that can be completed with the right tools and instructions. By following the steps outlined above, you can replace your water heater’s heating element with a low watt density element and enjoy hot water more efficiently and cost-effectively. If you’re not comfortable with electrical work, be sure to contact a professional plumber to assist you with the installation.
