3 Essential Tips to Make Your Water Heater Last Longer and Work More Efficiently

Posted December 28, 2024

Most homeowners purchase a conventional tank water heater and forget about it until it breaks down and needs replacement. However, with a few simple maintenance steps, you can significantly increase your water heater’s lifespan and improve its efficiency, saving both time and money.

1. Flush the Water Heater Tank Annually

Over time, sediment and mineral deposits accumulate at the bottom of your water heater tank. This sediment buildup reduces the efficiency of the burner, making your water heater work harder and increasing energy costs.

Flushing the tank annually helps remove this buildup. To flush your water heater:

  • Turn off the water heater and allow it to cool down.
  • Attach a garden hose to the drain valve at the bottom of the tank, ensuring the other end is placed outside or near a floor drain.
  • Open the drain valve and allow the water to flow out, flushing out sediment.
  • Close the valve, remove the hose, and refill the tank before turning the water heater back on.

Always check the manufacturer’s instructions for your specific model. If you’re unsure how to perform this step, contact a professional plumber for assistance.

2. Check and Replace the Anode Rod

The anode rod is a crucial component that prevents the inside of your tank from rusting. This rod, usually made of magnesium or aluminum, attracts corrosive elements in the water, sacrificing itself to protect the tank.

To check the anode rod:

  • Turn off the water heater and release pressure from the tank.
  • Unscrew the anode rod from the top of the tank and inspect it for heavy corrosion.
  • If the rod is less than 1/2 inch thick or heavily corroded, replace it with a new one.

Inspecting and replacing the anode rod annually is far cheaper than replacing a corroded water heater tank. A properly maintained anode rod can significantly extend the life of your water heater.

3. Insulate the Water Heater Tank

Insulating your water heater tank is a one-time task that can improve efficiency by up to 40%. This reduces heat loss and helps your water heater maintain a consistent temperature without overworking.

To insulate your water heater:

  • Purchase an insulation blanket designed for water heaters from a hardware store.
  • Wrap the tank, avoiding the top, thermostat, and burner compartments for gas water heaters.
  • Secure the blanket according to the manufacturer’s instructions.

Insulating the first 6 feet of hot and cold water pipes connected to the water heater can further reduce heat loss and improve efficiency.

Why Maintenance Matters

Routine maintenance not only extends the life of your water heater but also improves its performance, reduces energy consumption, and prevents costly repairs or replacements. By taking a few simple steps each year, you can ensure your water heater operates efficiently and reliably for years to come.
