Intro

Tankless water heaters are a smart, energy-efficient investment for many homes in Eastvale and Corona, CA. They provide endless hot water on demand, save space, and often last longer than traditional water heaters. But like any hardworking appliance, they require routine maintenance to keep running at peak performance—especially in areas with hard water like ours.

In this blog, we’ll break down why tankless water heater maintenance is essential, what homeowners in our area should look out for, and how regular servicing can extend the life of your system.

The Rise of Tankless Water Heaters in Eastvale & Corona

Over the last decade, tankless water heaters have become increasingly popular in Southern California homes, especially in growing communities like Eastvale and Corona. With modern home construction and a focus on energy efficiency, more homeowners are opting for these compact, high-performance systems.

But one thing many people don’t realize is that while tankless systems require less maintenance than traditional tanks, they don’t require no maintenance.

Why Maintenance Is So Important in Our Area

1. Hard Water Is a Big Deal Here
Eastvale and Corona both deal with hard water—water with high levels of calcium and magnesium. Over time, minerals can build up inside the unit’s heat exchanger and plumbing lines. This reduces efficiency, shortens the system’s lifespan, and can lead to expensive repairs or full replacements.

2. Protect Your Warranty
Many tankless water heater manufacturers require proof of regular maintenance to keep your warranty valid. Skipping annual service could mean you’re out of luck if something goes wrong.

3. Energy Efficiency and Cost Savings
Without maintenance, scale buildup can force your system to work harder than it should. That means higher utility bills and more strain on internal components.

4. Prevent Unexpected Breakdowns
Regular checkups catch issues early—like sensor problems, blockages, or failing parts—before they become a costly emergency.

What Does Tankless Maintenance Involve?

At Circle City Plumbing and Drain, a typical tankless water heater service includes:

• Descaling/Flushing the unit to remove mineral buildup
• Cleaning the inlet filter to ensure proper water flow
• Inspecting internal components for wear and corrosion
• Testing the system’s performance and temperature accuracy
• Checking the venting system for blockages or leaks

This can usually be completed in about an hour—and the peace of mind is well worth it.

How Often Should You Service Your Tankless Water Heater?

We recommend annual maintenance for most homeowners, though some homes with particularly hard water or heavy usage may need service every 6–9 months.

If you’ve never had your system serviced, or if you notice signs like:

• Inconsistent hot water
• Error codes on the unit
• Slower heating or reduced water flow

…it’s time to call in a professional.
