Water Heater Maintenance: What Actually Matters (and What Doesn’t)

Most homeowners either ignore maintenance or are told to do things that don’t make sense for their system.

At Hot Water Solutions, we take a practical approach based on what actually works in the field across Cobb, Cherokee, Paulding, and surrounding counties.

How Often Should You Maintain a Water Heater?

• Tank: Only if maintained consistently

• Tankless: Once per year

👉 Tankless systems benefit the most from maintenance.

Why Maintenance Matters

• Extends lifespan

• Improves efficiency

• Helps prevent breakdowns

But not all maintenance advice applies equally to every system.

Tank Water Heater Maintenance (Real Talk)

You’ll often hear:

• “Flush it yearly”

• “Replace the anode rod regularly”

👉 That can be true, but only if it’s been done consistently from early on

⚠️ If a tank has gone years without maintenance:

• Flushing can stir up sediment

• It can lead to leaks or failure

👉 This is why many older tanks are left alone unless there’s a reason to intervene

Tankless Water Heater Maintenance

This is where water heater maintenance matters most.

Key Tasks:

• Descaling the heat exchanger

• Cleaning inlet filters

• Inspecting system performance

👉 Important: Homeowners can do this themselves with a flush kit and basic instructions.

Professional service is helpful but not always required.

What Homeowners Should Watch For

• Leaks

• Strange noises

• Reduced hot water

• Error codes (tankless systems)

  
  

How Often?

• Tankless: Annually

• Tank: Only if it’s been consistently maintained

  
  

Bottom Line

Maintenance is important—but it has to be done the right way for your system.
