At Creative Comfort Solutions, we know how essential a reliable water heater is for your home’s comfort. Regular maintenance helps keep your system running efficiently, prevents costly repairs, and extends its lifespan. Whether you have a traditional tank or a tankless system, routine servicing ensures a steady supply of hot water while reducing energy waste.

Why Preventive Maintenance Matters

Over time, sediment buildup, worn-out components, and neglected systems can lead to inefficiencies, higher energy bills, and unexpected breakdowns. Regular maintenance helps:

  • Improve energy efficiency
  • Extend the lifespan of your water heater
  • Reduce the risk of leaks and damage
  • Ensure consistent water temperature and pressure
  • Lower utility costs by preventing unnecessary energy waste

Key Components of Water Heater Maintenance

Flushing the Tank

Sediment from minerals in the water supply can accumulate at the bottom of a traditional tank water heater. This buildup reduces efficiency, increases heating time, and can cause the unit to overheat. Flushing the tank annually removes this sediment and helps maintain peak performance.

Inspecting and Replacing the Anode Rod

The anode rod is a crucial component that prevents rust inside the water heater tank. Over time, it corrodes and must be replaced to protect the tank from rusting and leaking. Checking and replacing the anode rod every three to five years helps prolong the life of your system.

Checking for Leaks and Corrosion

Leaks around the base of the heater, connections, or pressure relief valve can indicate underlying issues. Corrosion on the tank or pipes can weaken the system and lead to water damage. A professional inspection can catch small problems before they become major repairs.

Testing the Temperature and Pressure Relief (TPR) Valve

The TPR valve is a critical safety feature that releases excess pressure to prevent the tank from bursting. It should be tested regularly to ensure proper function and prevent dangerous pressure buildup.

Adjusting the Temperature Settings

Setting your water heater’s thermostat to 120°F ensures optimal energy efficiency while preventing scalding. A lower temperature setting also helps reduce energy consumption and extends the unit’s lifespan.

Inspecting Gas or Electrical Components

Gas water heaters require checking the burner, gas lines, and ventilation to ensure safe operation. Electric water heaters need an inspection of heating elements and wiring to detect any issues before they cause failure.

Cleaning the Air Intake or Ventilation System

Tankless water heaters require additional maintenance, such as cleaning air intake filters, flushing the system to remove mineral buildup, and keeping the unit free from dust and debris to maintain efficiency and performance.

How Often Should You Service Your Water Heater?

  • Tank Water Heaters – Annually, with anode rod inspection every three to five years.
  • Tankless Water Heaters – Every one to two years, including descaling and ventilation checks.
  • Gas Water Heaters – Yearly inspections for burner efficiency and ventilation safety.

Signs Your Water Heater Needs Maintenance

If you notice any of the following, it may be time to schedule a maintenance check:

  • Fluctuating water temperatures
  • Rust-colored or cloudy water
  • Strange noises coming from the tank
  • Water leaks around the heater
  • Higher-than-usual energy bills

FAQs About Water Heater Maintenance

How long does water heater maintenance take?

A standard maintenance check typically takes 45 minutes to an hour, depending on the condition of the unit.

Can I flush my water heater myself?

While homeowners can flush the tank using a hose, professional servicing ensures thorough cleaning and proper inspection of other components.

Does maintenance help lower energy bills?

Yes, regular maintenance improves efficiency and reduces energy waste, leading to lower monthly utility costs.

What happens if I don’t maintain my water heater?

Neglecting maintenance can lead to sediment buildup, reduced efficiency, higher energy bills, leaks, and premature system failure.

When should I replace my water heater instead of maintaining it?

If your unit is over 10 to 15 years old, has frequent issues, or requires costly repairs, replacement may be the best option.
