Complete tutorial: how to swap out your electric water heater step by step

Replacing an electric water heater can seem daunting, but with the right tools and a little know-how, you can tackle this project yourself and save money in the process. This comprehensive guide will walk you through every step of the process, ensuring a successful and safe replacement.

Gather Your Materials

Before you start, gather the following materials:

• New electric water heater
• Water heater connectors
• Dielectric unions
• Teflon tape
• Electrical wire and connectors
• Plumber’s putty
• Adjustable wrench
• Pipe wrench
• Screwdriver
• Voltage tester
• Safety glasses

Step 1: Safety First

Before handling any electrical components, turn off the power to the water heater at the circuit breaker or fuse box. Also, shut off the water supply to the heater. Open a hot water faucet to relieve pressure.

Step 2: Disconnect the Old Water Heater

Disconnect the water lines from the water heater by unscrewing the connectors with an adjustable wrench. Use a pipe wrench to remove the electrical wires from the terminals.

Step 3: Remove the Old Water Heater

Carefully lift the old water heater out of the tank stand and place it on a dolly or cart for easy removal.

Step 4: Install the New Water Heater

Place the new water heater in the tank stand and connect the water lines using the connectors and dielectric unions. Wrap Teflon tape around the threads to ensure a leak-free connection.

Step 5: Connect the Electrical Wires

Connect the electrical wires to the terminals on the new water heater. Use wire connectors and electrical tape to secure the connections.

Step 6: Test the Electrical Connections

Turn on the power to the water heater and use a voltage tester to ensure that the connections are made correctly.

Step 7: Fill and Bleed the Water Heater

Open the water supply valve and allow the water heater to fill. Once it’s full, open a hot water faucet to bleed any air from the system.

Step 8: Set the Temperature

Adjust the temperature setting on the water heater to your desired temperature.

Flushing the Water Heater

After the installation is complete, it’s important to flush the water heater to remove any sediment or debris that may have accumulated during the replacement process. Here are the steps to flush the water heater:

• Connect a garden hose to the drain valve at the bottom of the water heater.
• Open the drain valve and allow the water to flow through the hose until it runs clear.
• Close the drain valve and disconnect the hose.

Troubleshooting

If you encounter any issues during the replacement process, refer to the following troubleshooting tips:

• Leaking water: Check the connections for leaks and tighten them as needed.
• No hot water: Ensure that the electrical connections are secure and that the thermostat is set to the correct temperature.
• Water heater not heating: Check the circuit breaker or fuse to ensure that the power is on. Also, inspect the heating element for any damage.
