tankless water heater repair

Tankless water heaters are amazing for supplying your home with on-demand hot water. But just like any other appliance, they need a bit of regular maintenance to stay in top shape. 

Following a few simple tips, you can avoid surprise issues and the hassle of a tankless water heater repair—keeping it running smoothly for years to come.

Here are some easy ways to maintain your tankless water heater.

1. Flush the System Regularly

Mineral buildup is the number one enemy of tankless water heaters. Over time, minerals like calcium can settle in the system, affecting performance and damaging parts. Flushing your tankless water heater every 6 to 12 months (especially if you have hard water) can help prevent this.

Many homeowners can do it themselves with the help of the manufacturer’s instructions, but a plumber can also do the job quickly and safely.

2. Check the Inlet Filter

Your water heater’s inlet filter helps keep debris from entering the unit, but it can get clogged over time. Checking and cleaning this filter periodically is an easy way to keep the system running smoothly.

A clean filter means better water flow and less chance of needing a tankless water heater repair due to blockages.

3. Use a Water Softener if You Have Hard Water

If you live in an area with hard water, your tankless water heater will benefit from a water softener. Hard water leads to more mineral buildup, which can cause efficiency issues and wear down the heater.

Installing a water softener can significantly reduce scaling, helping your water heater last longer and work better.

4. Keep the Vent Area Clear

Tankless water heaters need proper ventilation to work safely. If the air intake or exhaust vents get blocked—by dust, leaves, or even items stored nearby—it can cause the unit to overheat. 

Check your vents regularly to make sure they’re clear, and keep the area around your heater free so it has room to “breathe.”

5. Set a Moderate Temperature

Setting your tankless water heater at a high temperature can put extra stress on the unit. Most manufacturers recommend keeping it around 120°F, which is hot enough for most household needs.

A lower temperature reduces the risk of mineral buildup and general wear, helping prevent tankless water heater repair down the line.

6. Schedule a Yearly Professional Checkup to Avoid Water Heater Repair

You can do a lot to keep your tankless water heater in good shape, but it’s still worth having a professional check it over once a year. A licensed plumber can look for any issues you might miss, clean hard-to-reach spots, and make sure everything’s running smoothly.

This small investment in annual maintenance can go a long way toward preventing big repair bills later.

Keep Your Tankless Water Heater Problem-Free

With just a little attention now and then, you can help your tankless water heater stay in peak condition and avoid the need for repairs. A few simple steps can make all the difference in keeping your system efficient, reliable, and ready for anything.
