Water heater elements can go bad for various reasons. The most common reason is from sediment buildup. When heated water sits in the tank, sediment builds up on the elements, which can decrease the water heater’s efficiency and cause the element to overheat.
This can lead to premature failure. Other causes of element failure include excessive electrical current, incorrect sizing, corrosion, and mineral deposits. It is important to keep your water heater maintained and clean to avoid element failure and extend the life of the unit.
Cleaning the unit regularly and replacing anode rods can help minimize the risk of failure.
How long should a water heater element last?
The life expectancy of a water heater element will vary greatly depending on a few factors. Generally, a standard element should last around 8 to 12 years, but elements installed in areas with hard water (with higher concentrations of minerals) will last shorter served, while those in areas with softer water may last significantly longer—up to 20 years.
Other factors, such as proper installation, how often you use your water heater, how much hot water you use, and how well your system is maintained, will also have an impact on a water heater element’s longevity.
Anode rods should also be inspected and replaced if necessary, as a worn out anode rod can lead to premature failure of an element. Proper maintenance is an essential component of a water heater element’s long-term performance.
Which element goes bad first in hot water heater?
The element that goes bad first in a hot water heater is usually the lower element, as it is typically closer to sediment and mineral deposits and is more prone to corrosion. The lower element is often more heavily used, experiences increased thermal stress and is normally at a lower wattage than the upper element, making it more likely to fail first.
The upper element generally lasts longer, due to the more consistent temperature and reduced rate of thermal stress. However, either element can go bad due to a variety of issues, such as corrosion from mineral deposits or a malfunctioning thermostat, pressure-relief valve, or control switch.
It is important to regularly check your hot water heater to ensure all elements are in good working order.
Should you replace both water heater elements at the same time?
When it comes to replacing your water heater elements, it is not necessarily a requirement to replace both of them at the same time. However, it is usually recommended to do so if you plan on replacing them.
This is because it helps to extend the life of the heater by reducing the overall stress on the tank. Additionally, it eliminates the risk of needing to replace one element a few years down the line, which could be costly.
Furthermore, replacing both elements at the same time ensures the heater operates more efficiently and evenly. Overall, although it may be more expensive to replacing them both, it will be beneficial in the long run.
Do you have to drain a water heater to replace the elements?
Yes, in most cases, you must drain a water heater to replace the elements. This is because the elements are usually located at the bottom of the tank, so you must empty the tank before you can access them.
If you try to replace the elements without draining the tank the chances of the elements being damaged or not seating correctly are greater. It is important to be aware of the size of the tank and the availability of draining methods before attempting this project.
Too much water removed too quickly can crack the tank, so it is best to be prepared to handle drainage slowly and methodically. Furthermore, before attempting this project, it is highly recommended that you follow all safety protocols as outlined in the owner’s manual for the water heater and always wear the appropriate safety gear such as long pants, closed-toe shoes, long-sleeve shirts, eye protection, and gloves.
What causes a heating element to burn out?
The most common cause of a heating element burning out is overload due to an excessively high current passed through the element for too long. This could be caused by a fault in the wiring, a control component such as a thermostat or relay, or a fault in the heating element itself.
Other causes could include an accumulation of dirt or dust which prevents good heat transfer from the element to its surroundings, excessive vibrations or impacts which can weaken the element, or being subjected to temperatures too high for its design tolerance.
Sometimes, a heating element will simply wear out over time due to continuous use.
How can I make my heating element last longer?
Here are some tips for ensuring your heating element lasts as long as possible:
1. Check for Blockages: Make sure there are no blockages preventing air from reaching the heat source. A blocked filter or heat exchanger can cause the heating element to overheat and fail.
2. Change the Filter: Change the filter regularly, as a clogged filter restricts airflow and causes premature failure of the heating element.
3. Monitor Operating Temperatures: Monitor the operating temperatures of the system, as overheating could damage the heating element.
4. Clean Surface Areas: Make sure the surrounding surfaces are dust and debris free, as this could increase the temperature of the heating elements.
5. Inspect Regularly: Regularly inspect the heating element for any signs of wear or damage. If any issues are found, they should be addressed immediately to avoid further potential damage.
6. Use the Appropriate Voltage: Ensure the voltage supplied to the heating element is appropriate for the manufacturer’s requirements. Improper voltage can cause the heating element to fail prematurely.
