Introduction

Greetings dear readers! A water heater is an essential appliance in your home, especially during the winter season. And when the heating element in your water heater malfunctions, it can be a real inconvenience. But don’t worry! In this guide, we will teach you how to change the heating element in your water heater, step by step. So, let’s get started!

What is a Heating Element in a Water Heater?

A heating element is a crucial component of a water heater that is responsible for heating the water whenever you need it. Most water heaters have two heating elements: one at the top and one at the bottom. These heating elements are made of metal and are designed to heat the water as it passes through the tank. Over time, the heating elements can wear out and fail, which can cause your water heater to malfunction.

Why Do You Need to Change the Heating Element?

If your water heater is not producing hot water or takes longer than usual to heat up, it’s likely that the heating element has failed. In such cases, you need to replace the heating element as soon as possible to avoid further damage and inconvenience.

What Are the Types of Heating Elements?

There are two types of heating elements used in water heaters: nickel-chromium (NiCr) and copper. NiCr heating elements are the most common type and are less expensive. On the other hand, copper heating elements are more corrosion-resistant and have a longer lifespan. In this guide, we will focus on replacing the NiCr heating element, which is the most common type of heating element used.

What Tools Do You Need?

Before we begin, here are the tools and equipment you will need:

Tools Equipment
Adjustable wrench New heating element
Screwdriver Heating element gasket
Socket wrench Thread sealant
Multimeter A bucket
Wire stripper Water pump pliers

How to Change Heating Element in Water Heater

Step 1: Turn Off the Power and Water Supply

Before you begin, make sure to turn off the power supply to the water heater. You can either turn off the circuit breaker that powers the water heater or unplug it from the power source. Next, turn off the water supply valve that feeds water to the heater. Open a hot water faucet to relieve pressure and drain the water in the tank.

Step 2: Remove the Access Cover and Inspect the Heating Element

Locate the access cover on the side of the water heater. Remove the screws that hold the access cover in place using a screwdriver. Once the cover is off, inspect the heating element with a multimeter to check if it’s working. If the heating element is faulty, continue to the next step.

Step 3: Disconnect the Wires from the Heating Element

Using a wire stripper, remove the insulation from the wires that go to the heating element. Use an adjustable wrench or water pump pliers to remove the nuts that secure the wires to the heating element. Make a note of which wire goes to which terminal to avoid confusion later.

Step 4: Remove the Old Heating Element

Using a socket wrench, remove the nuts that secure the heating element to the tank. Gently pull the heating element out of the tank, being careful not to damage the tank or the gasket. If the heating element is stuck, use a wrench to loosen it or tap it with a hammer gently.

Step 5: Install the New Heating Element

Apply thread sealant to the threads of the new heating element to prevent leaks. Insert the new heating element into the hole in the tank, and secure it in place with the nuts. Tighten the nuts firmly but not too tight to avoid damaging the gasket.

Step 6: Reconnect the Wires

Attach the wires to the new heating element by securing them with the nuts. Make sure that the wires are connected to the correct terminals. Replace the insulation on the wires.

Step 7: Turn On the Water Supply and Power

Turn on the water supply valve to fill the tank with water. Shut off the hot water faucet once water starts coming out smoothly. Finally, switch on the power supply to the water heater. Once the water is heated, test it by turning on the hot water faucet. If the water is hot, you have successfully changed the heating element!
