Do Tankless Water Heaters Need Tune-ups?


You’ve made the transition from a tank to a tankless water heater. You’re undoubtedly enjoying the many advantages it offers such as lower utility bills and a constant supply of hot water. You’re so impressed with its performance that it might feel like it’s infallible and that nothing will hinder its performance.

Well, we’re here to tell you that if you want to continue to be impressed by it, you still need occasional tankless water heater service. After all, tune-ups are the best way to make sure you continue to have unbeatable performance–not to mention investing in the life of your system! Read on to learn more about why tankless water heaters still need tune-ups.

Scaling in Water Heaters

Scaling is a concept you’re well familiar with when you live in Salt Lake City, UT. That’s because scaling is the result of our hard water which contains high amounts of magnesium, calcium, and sometimes iron. Although these minerals are safe to ingest, they can eventually wreak havoc on your home’s pipes, plumbing, and appliances, including your water heater. 

Scaling impacts the heat exchanger of any type of water heater. The heat exchanger is the component responsible for heating up the water. Hard water deposits tend to accumulate on the heat exchangers which impedes the water heater’s ability to heat water efficiently. Scaling makes the burners work harder and can overwork the system to the point that it breaks down.

Frequency of Maintenance Tune-Ups

A water heater flush is one of the things our team of plumbers will perform during a tune-up. Flushing a water heater gets rid of all the mineral buildup to help prevent scaling. Ideally, this should be done once a year. It could be less often but it depends on the level of hard water in your area and if your home has a water softener installed to combat hard water.

Other Benefits of Water Heater Tune-Ups

A tune-up has many other benefits besides reducing the ill effects of hard water. Maintenance is an investment in the longevity of your tankless water heater. It helps your tankless water heater work at maximum efficiency to keep your utility bills low as well. 

In addition to flushing the tank, the technician will check the anode rod to see if it needs to be replaced. Ignoring the anode rod is going to result in a rusted, broken-down water heater, so this is an essential part of the maintenance visit. 

They’ll also check that the temperature is at the recommended temperature which should be around 120º F. You can save up to 5% in energy costs for every 10º F that you lower the temperature. 

If the water isn’t hot enough, it could be a faulty thermostat. If the thermostat is not operating properly, it will need to be repaired or replaced. Lastly, they’ll also check the water pressure to make sure it’s at the correct level.
