Essential Guide to Water Heater Maintenance

Water heater maintenance is crucial to ensuring its longevity and efficiency. Regular maintenance not only helps you avoid unexpected breakdowns but also improves the unit’s performance, saving energy and reducing utility bills. 

Here’s a comprehensive guide to water heater maintenance

Understanding Your Water Heater 

There are primarily two types of water heaters: tank and tankless. Tank water heaters store and heat a large volume of water continuously, while tankless water heaters heat water on demand. Despite their differences, both types require regular maintenance to function optimally. 

Annual Inspection 

Conducting an annual water heater inspection is a good practice. Start by checking for any visible signs of wear and tear, such as:

  • Rust
  • Leaks
  • Corrosion

Pro Tip: Ensure that the area around the water heater is clean and free from flammable materials.

Checking the Pressure Relief Valve 

The pressure relief valve is a safety feature designed to release excess pressure if the tank overheats. To test your valve:

  • Place a bucket under the discharge pipe.
  • Lift the valve lever.
  • Allow some water to flow out.

If the valve does not release water or leaks after the test, it may need to be replaced.

Flushing the Tan

Sediment buildup at the bottom of the tank can reduce efficiency and damage the heater. Flushing the tank annually helps to remove these sediments. 

Here’s how you can do it in 5 easy steps: 

  • Turn Off the Power: For electric water heaters, turn off the power at the circuit breaker. For gas heaters, set the thermostat to the “pilot” setting. 
  •  Shut Off the Water Supply: Close the cold-water supply valve to the water heater. 
  • Drain the Tank: Attach a garden hose to the drain valve at the bottom of the tank and run the hose to a suitable drainage location. Open the drain valve and allow the tank to empty completely. Be cautious as the water may be hot. 
  • Flush the Tank: With the drain valve open, turn on the cold-water supply to flush out any remaining sediment. Continue until the water runs clear. 
  • Refill the Tank: Close the drain valve, remove the hose, and turn on the cold-water supply to refill the tank. Once the tank is full, restore power to the water heater.

Inspecting the Anode Rod 

The anode rod is a crucial component that prevents tank corrosion by attracting corrosive elements. Inspecting and replacing it every 3-5 years can significantly extend the life of your water heater. 

To check the anode rod: 

  • Turn Off the Power and Water Supply: As with flushing the tank, ensure the power is off and the water supply is closed. 
  • Locate the Anode Rod: It is usually located on the top of the tank. Remove it using a socket wrench. 
  • Inspect the Rod: If the rod is heavily corroded or less than half an inch thick, it’s time to replace it. 
  • Install a New Rod: Insert the new anode rod into the tank, tighten it securely, and restore the water and power supply.

Adjusting the Thermostat 

Setting the thermostat to 120°F (49°C) is recommended for optimal efficiency and safety. This temperature is hot enough to meet your needs but reduces the risk of scalding and minimizes energy consumption. 

Insulating the Heater

Insulating your water heater and the pipes can reduce heat loss and improve efficiency. Use an insulating blanket for the tank and pre-slit foam pipe insulation for the pipes. 

Pro Tip: Make sure not to cover the thermostat or any controls.

Keep Your Water Heater in Tip-Top Shape

Regular maintenance of your water heater is essential for its longevity and efficiency. By performing annual inspections, flushing the tank, inspecting the anode rod, adjusting the thermostat, and insulating the heater, you can ensure a steady supply of hot water while minimizing energy costs and avoiding costly repairs or replacements
