ToggleWhat is a Tankless Water Heater?
A tankless water heater is like a magic box that heats water only when you need it. Instead of storing hot water in a big tank, it heats the water as it flows through the pipes. This means you won’t run out of hot water when you’re taking a shower or washing dishes. Isn’t that great?
How Does It Work?
When you turn on the hot water tap, cold water travels through a pipe into the unit. A flow sensor detects the water coming in, and the heater turns on. This is when electricity or gas ignites and heats the water right away. Because it doesn’t keep a lot of water hot all the time, tankless heaters are usually more energy-efficient.
Why is Maintenance Important?
Just like how you brush your teeth every day to keep them clean, your tankless water heater needs some regular attention too. If you take care of it, it can last a long time and save you money. A well-maintained heater also works better and provides you with hot water when you expect it.
Benefits of Regular Maintenance
- Longer Lifespan: Taking care of your heater means it will last longer, sometimes up to 20 years!
- Better Efficiency: Regular maintenance helps your heater work well, so you get hot water quickly without wasting energy.
- Fewer Repairs: Fixing small problems early means you won’t have big, expensive issues later on.

Basic Maintenance Tasks You Can Do
Here are some monthly and yearly tasks you can do to keep your tankless water heater in tip-top shape.
Monthly Tasks
-
Check the Air Filter: If your unit has an air filter, make sure to check it once a month. Dust and dirt can block airflow, making your heater work harder. If it looks dirty, clean it or replace it.
-
Inspect for Leaks: Look around the heater for any signs of leaking water. If you see a puddle or dripping, it’s time to call a professional.
-
Flush the System: The water you use might have minerals, like calcium, that can build up in the heater. Use the flush valve at least once a month to release any stored minerals. This keeps the water flowing smoothly.
Yearly Tasks
-
Descale the Heater: Over time, limescale can build up, making your heater less efficient. You should descale your heater once a year. This means running a special solution through it to clean it out.
-
Check the Venting System: Make sure that the venting for your heater remains free from obstructions. Look for signs of soot or damage. If something looks wrong, get it checked.
-
Inspect the Burner: If you have a gas tankless water heater, make sure to check the burner. It should be clean and able to ignite the gas correctly. If you see rust or dirt, it’s best to have a technician clean it.
Advanced Maintenance Tasks
Some things are better left to the experts. Here are some tasks you should consider having a professional handle.
Annual Tune-Up
Calling a professional for a yearly check-up can help keep major problems away. A certified technician will:
- Inspect the entire unit for wear and tear.
- Clean internal components that you can’t reach.
- Check your electrical or gas connections.
Pressure Relief Valve Inspection
Your heater might have a pressure relief valve to prevent too much pressure from building up. It’s good to have this checked by a pro once a year. This helps keep everything safe.
Flushing the System
While you can flush the system yourself, a professional knows how to do it the right way. They can ensure that all the mineral buildup is washed away, which will help your heater work better.

Signs Your Tankless Water Heater Needs Help
Sometimes, your heater will let you know that it needs attention. Here are some signs to look out for:
Erratic Temperature
If the water temperature goes up and down while you’re using it, your heater might be having trouble. This could be caused by limescale build-up or a faulty part.
Strange Noises
If your tankless heater starts making weird sounds—like banging or hissing—it might be time to call a technician. These sounds often indicate that something isn’t right.
Low Water Pressure
If you notice that your hot water pressure is lower than usual, this could also suggest a blockage or a problem inside the heater.
How to Choose a Reliable Technician
If you find that your tankless water heater needs repairs or maintenance that you can’t do alone, it’s essential to find a good technician. Here’s how:
Check Qualifications
Make sure the technician has proper certification. You want someone with knowledge about tankless systems.
Read Reviews
Look at what other customers say about their experiences. Websites and social media can help you find a trustworthy company.

Don’t be afraid to get different quotes. This can help you find the best price for quality work.

As helpful as tankless water heaters can be, they can still run into some common issues. Here are some problems to look out for:
Inconsistent Heating

Low Flow Rate
