A water heater is an important appliance in your home. It gives you hot water for showers, washing dishes, and doing laundry. Even though it’s used daily, people often forget about it, until it stops working. If you ever face issues with your unit, contacting a professional Plumber in Oxford can ensure proper inspection and maintenance. Knowing how long a water heater typically lasts and how to properly care for it can help you avoid cold showers and costly repairs.
How Long Does a Water Heater Last?
Most traditional water heaters with a tank last about 8 to 12 years. Tankless water heaters, which heat water only when needed, can last up to 20 years or more.
Several things affect how long a water heater lasts:
- Type: Tankless models usually last longer than traditional ones. Electric heaters may last longer than gas ones.
- Water Quality: If you have hard water (water with lots of minerals), it can damage your heater faster.
- Usage: Larger families or homes with heavy water use may wear out a heater more quickly.
- Maintenance: Regular care can help your heater last longer.
How to Make Your Water Heater Last Longer
1. Flush the Tank
Minerals from hard water can build up inside the tank and make your heater less efficient. Flushing the tank once a year removes these deposits.
How to do it:
- Turn off the power (or gas).
- Attach a garden hose to the drain valve.
- Let the water drain out completely.
- Close the valve, remove the hose, and refill the tank.
If you’re not sure how to do this, call a plumber.
2. Check the Anode Rod
This rod prevents the tank from rusting. It should be checked every 2–3 years. If it’s very thin or corroded, replace it.
3. Insulate the Tank and Pipes
Insulating the heater and pipes keeps the water hot longer, reduces energy use, and eases the workload on your heater. You can purchase specially designed insulation blankets for water heaters.
4. Test the Pressure Relief Valve
This valve keeps too much pressure from building up in the tank. Once a year, lift the valve’s lever and let some water out. If it doesn’t work properly, replace it.
5. Lower the Temperature
Most heaters are set to 140°F, which is higher than needed. Setting it to 120°F saves energy and reduces wear.
6. Get Professional Help
Have a plumber inspect your water heater every couple of years. They can spot problems you might miss and perform detailed checks.
When to Replace It
You may need a new one if:
- It’s over 10 years old.
- The water is rusty
- It’s making loud noises.
- You notice leaks around the base.
Conclusion
Taking care of your water heater means fewer problems and more years of reliable hot water. Regular maintenance, combined with professional assistance when needed, can help keep your heater functioning properly for an extended period. If it’s getting old, consider replacing it before it fails completely.
