Essential Tips for Water Heater Efficiency

April 18, 2025

A reliable water heater is essential for everyday comfort, from warm showers to clean dishes. However, without proper care, it can become inefficient, increasing energy costs and shortening its lifespan. Fortunately, Garner Plumbing Services helps homeowners keep their water heaters running smoothly with expert installation, maintenance, and repairs.

Signs of a Hidden Leak

A failing water heater often gives warning signs before it stops working. Addressing issues early, such as water heater efficiency, can prevent costly repairs or replacements.


  • Inconsistent Water Temperature: If your hot water fluctuates, your heater may have sediment buildup or a faulty heating element.
  • Strange Noises: Popping or rumbling sounds often indicate sediment buildup, which reduces efficiency and can damage the tank.
  • Discolored Water: Rusty or cloudy water may signal corrosion inside the tank, a problem that worsens over time.
  • Leaks Around the Unit: Even small leaks can lead to significant water damage and signal the need for immediate repair.
  • Higher Energy Bills: An inefficient water heater works harder, using more energy and raising your monthly costs.

How to Improve Water Heater Efficiency

Maintaining your water heater can extend its lifespan and lower energy bills. These simple steps keep your system in peak condition:


  • Flush the Tank Annually: Draining sediment from the tank improves efficiency and prevents overheating.
  • Check the Anode Rod: This rod prevents rust inside the tank. Replacing it every few years can extend the heater’s life.
  • Insulate the Tank and Pipes: Adding insulation reduces heat loss, helping your heater maintain temperature with less energy use.
  • Adjust the Temperature: Setting the thermostat to 120°F provides hot water while preventing scalding and reducing energy consumption.
  • Schedule Professional Maintenance: A licensed plumber can inspect your water heater for issues before they become major problems.

When to Upgrade to a Tankless Water Heater

If your current water heater is over 10 years old, upgrading to a tankless water system can save space and improve efficiency. Tankless water heaters provide endless hot water while using less energy, making them a smart long-term investment.
