Preventing water heater issues is about regular care and attention. Here’s a detailed breakdown of the best practices to keep your water heater running smoothly:
1. Perform Regular Maintenance
Having a professional inspect your water heater at least once a year helps identify small issues before they escalate. Technicians can check for signs of corrosion, leaks, or faulty components. Early detection can save you from costly repairs or replacements.
2. Flush the Tank Annually
Mineral deposits, especially in hard water areas, settle at the bottom of the tank over time. These sediments can insulate the heating elements, making the water heater less efficient and increasing energy costs. Flushing the tank removes these deposits and ensures efficient heating. To do this, turn off the power and cold water supply to the heater, then drain it using the valve at the bottom. A professional can also perform this task during routine maintenance.
3. Set the Thermostat to 120°F
Many homeowners set their water heater thermostats too high, thinking hotter water is better. However, temperatures above 120°F can cause the water heater to work harder, wasting energy and risking overheating. In addition, setting it too high can also lead to scalding water accidents. Keeping the thermostat at 120°F balances comfort and energy efficiency.
4. Inspect and Replace the Anode Rod
The anode rod is a key part of your water heater that prevents rust and corrosion. It attracts corrosive elements in the water, which would otherwise damage the tank. Over time, the rod corrodes itself, and if not replaced, your water heater’s tank will rust and leak. You should inspect the anode rod every 2-3 years and replace it when it’s more than 50% worn down.
5. Insulate the Water Heater and Pipes
Heat loss through uninsulated tanks and pipes can increase energy bills. Insulating your water heater, especially if it’s an older model or located in a colder area, can prevent heat from escaping and maintain water temperature more efficiently. Insulating the hot water pipes helps prevent heat loss between the heater and taps, ensuring water remains at the right temperature when you need it.
6. Check the Temperature and Pressure Relief Valve
This valve is a safety feature that prevents the tank from building up too much pressure, which could cause it to rupture. Over time, mineral deposits or corrosion can affect its function. Test it annually by lifting the valve lever. If water doesn’t flow out, it’s time to call a professional. A malfunctioning T&P valve could be dangerous and should be replaced immediately.
7. Monitor Water Quality
In areas with hard water, mineral buildup can be more severe, leading to clogs, poor performance, and shorter lifespan of your water heater. Consider installing a water softener if your area has hard water. This can protect the heating elements and reduce sediment buildup in the tank.
8. Know When to Replace Your Water Heater
Even with all the preventive measures, your water heater has a lifespan of about 10-15 years. If your unit is approaching this age and experiencing frequent issues, it may be time to replace it. Continuing to repair an old water heater can cost more in the long run than investing in a new, more efficient model.
