How to Maintain Your Tankless Water Heater for Efficiency & Longevity

 Tankless water heaters are becoming increasingly popular in homes across Jonesboro, AR due to their energy efficiency, endless hot water supply, and long lifespan. But just like any other appliance, they require regular care to run at peak performance. If you want your system to last for years and avoid costly repairs, proper maintenance is essential.

At Chris West Plumbing, we specialize in tankless water heater services in Jonesboro, AR, and we’re here to guide you through the key steps to keep your unit efficient and reliable.

Why Maintenance Matters for Tankless Water Heaters

Unlike traditional water heaters, tankless units heat water on demand. This reduces energy waste, but it also means mineral buildup, clogged filters, or reduced flow can directly impact performance.

Regular maintenance helps you:

  • Improve energy efficiency

  • Reduce utility bills

  • Extend the lifespan of the system

  • Maintain consistent water temperature

  • Prevent unexpected breakdowns

For best results, homeowners should schedule annual inspections with professional plumbers in Jonesboro, AR — especially if you have hard water, which speeds up scale accumulation.

1. Descale the System Annually

Mineral buildup is the biggest enemy of tankless water heaters. Hard water leaves calcium and magnesium deposits that block heat exchangers, reducing efficiency and increasing wear.

What to Do:

  • Descale or “flush” the system once a year

  • Use a pump, hoses, and descaling solution (or white vinegar)

  • Ensure the system runs the solution through the heater for 45–60 minutes

If you’re not comfortable doing this yourself, call Chris West Plumbing, your trusted experts in Plumbing Jonesboro AR, and we’ll handle it safely and professionally.

2. Clean the Water and Air Filters

Tankless systems rely on proper airflow and clean water to function efficiently.

Water Filter

  • Located near the cold-water inlet

  • Remove and rinse every 6 months

  • More frequent cleaning if your home has sediment issues

Air Filter

  • Typically located near the intake

  • Remove dust or lint buildup

  • Clean using mild soap and water

Keeping these filters clean helps your tankless unit breathe and operate smoothly.

3. Check the Venting System

Blocked or improperly installed venting can cause overheating or unsafe gas buildup.

Maintenance Tips:

  • Ensure there are no obstructions

  • Check for corrosion or loose fittings

  • Make sure outside vents are clear of leaves, dirt, or pests

If you notice strange noises, reduced airflow, or warning lights, contact Plumbers Jonesboro AR immediately for a professional inspection.

4. Inspect for Leaks and Corrosion

Even minor leaks can cause major damage over time.

Check the following areas:

  • Inlet and outlet pipe connections

  • Pressure relief valve

  • Heat exchanger area

  • Gas lines (for gas tankless units)

If you spot moisture or rust, schedule a service call with Chris West Plumbing right away.

5. Monitor Water Temperature Settings

Most tankless water heaters are set around 120°F — the safe and energy-efficient standard.

Why this matters:

  • Higher temperatures increase scale buildup

  • Energy costs rise

  • Internal components wear faster

If you need help adjusting your system, our team can guide you through the proper settings.

6. Schedule Professional Maintenance

Even if you perform DIY maintenance, a yearly inspection by certified plumbers in Jonesboro, AR ensures:

  • Full diagnostic testing

  • Checking error codes

  • Evaluating flow rates

  • Ensuring safe gas combustion

  • Verifying proper venting and electrical connections

Professional servicing eliminates hidden issues before they become expensive repairs.

Final Thoughts

A well-maintained tankless water heater can last 15–20 years, providing efficient, reliable hot water for your household. With regular cleaning, descaling, and professional inspections, you can keep your system running at its best.
