How to replace an electric water heater heating element
People & Blogs
Introduction
Changing the heating elements in an electric water heater is a task that many homeowners might encounter. In this guide, we will walk through the steps required to replace the heating elements in a 50-gallon electric water tank. This process is not just related to home maintenance but also ties into maintaining your farm's water system. So let's get started!
Step 1: Safety First
Before you begin, it’s crucial to ensure safety. The first step is to turn off the breaker supplying power to the water heater. This is usually a 220-volt supply, which can cause serious injury or be fatal if mishandled. Always verify that the power is off using a circuit tester. For our scenario, the power was already off, indicating that the element may have tripped the breaker.
Step 2: Drain the Tank
Under normal circumstances, you would attach a hose to the water tank’s drain valve to empty it. However, due to calcium buildup from well water, this may not always be feasible without messy consequences. In this case, you can choose to remove the top element directly to let some water escape, using buckets to catch the water as it drains. Remember to also turn off the hot water supply to prevent draining the entire house.
Step 3: Removing the Old Elements
Using a suitable socket wrench (often an inch-and-a-half), you can carefully remove the old heating elements. The threads are standard, but ensure you start unscrewing the elements by hand to avoid cross-threading. Once removed, check for any buildup, which could indicate why the element failed.
Step 4: Installing the New Elements
Once you have removed the old elements, it's time to install the new ones. Ensure that you have the correct specifications, such as voltage (usually 240V) and wattage (commonly 4500W).
- Preparation: Loosen the screws slightly on the new element without removing them completely.
- Positioning: Place the wires onto the back side of the element for better contact, ensuring that any rubber gaskets are in place.
- Tightening: Use a socket to securely fasten the element, tightening until it's snug—typically a quarter turn after it stops.
Step 5: Final Checks and Cleanup
After installation, double-check that all wires are intact and correctly connected. Make sure there is no moisture present in electrical compartments, as this poses an electrocution hazard. Clean up any spills and ensure all panels and insulation are properly placed back to maintain heat efficiency.
Step 6: Reconnect Power and Check for Leaks
Finally, turn the water supply back on and check for any leaks. If you encounter any leaking at the packing nut of hot water valves, try tightening them or consider getting them rebuilt. Once satisfied with the connection and the absence of leaks, flip the breaker back on to restore power to the heater.
Maintain your water heater by performing these replacements as necessary, especially if you have a well system prone to calcium buildup.

FAQ
Q: How often should I replace the heating elements in my water heater?
A: It's generally recommended to check and potentially replace heating elements every 3 to 5 years, especially if you notice issues with water temperature or calcium buildup.
Q: Can I replace the heating elements myself?
A: Yes, if you are comfortable working with electrical systems, you can replace the heating elements yourself by following safety protocols and instructions. However, if you are unsure, it's best to hire a professional.
Q: What tools do I need to replace the heating elements?
A: Typically, you will need a socket wrench (usually an inch-and-a-half) and a circuit tester to ensure that the power is off before starting the replacement.
Q: What should I do if my water heater is leaking?
A: If your water heater is leaking, turn off the power and water supply immediately. Check the connections for tightened screws or consider consulting a plumber for repair or replacement options.
Q: Is it necessary to drain the tank before replacing the elements?
A: While it is standard practice to drain the tank, high calcium buildup may complicate this process. If you are comfortable with some mess, you can replace the elements without completely draining the tank by allowing some water to escape.
