Do Tankless Water Heaters Need Maintenance? A Complete Guide
Tankless water heaters are becoming increasingly popular due to their efficiency and convenience. But like all appliances, they require proper maintenance to keep them functioning optimally. In this article, we’ll explore why tankless water heaters need maintenance, how often they should be serviced, and what maintenance entails.
Why Is Maintenance Important for Tankless Water Heaters?
Tankless water heaters are efficient and reliable, but they aren’t maintenance-free. Regular maintenance ensures that they continue providing hot water efficiently while minimizing the risk of costly repairs. Here are a few reasons why maintaining your tankless water heater is crucial:
Prevent Mineral Buildup
Tankless water heaters are susceptible to mineral buildup, especially in areas with hard water. Over time, calcium and magnesium deposits can accumulate in the heat exchanger, reducing the unit’s efficiency and even leading to damage if left unchecked. Regular maintenance helps prevent this buildup, keeping your unit running smoothly.
Prolong the Life of the Unit
Proper maintenance can extend the lifespan of your tankless water heater. Regular servicing helps detect and address small issues before they escalate into major problems, ensuring that your unit continues to perform effectively for years to come.
Ensure Efficient Performance
A tankless water heater that isn’t maintained can become less efficient over time, leading to increased energy usage and higher utility bills. By performing regular maintenance, you can ensure that your unit operates at peak efficiency, providing hot water when you need it without wasting energy.
How Often Should You Maintain a Tankless Water Heater?
The frequency of maintenance depends on factors like water hardness and the manufacturer’s recommendations. Generally, it’s a good idea to have your tankless water heater professionally serviced at least once a year. If you live in an area with hard water, you may need to perform descaling more frequently—every six months—to prevent mineral buildup.
Steps Involved in Tankless Water Heater Maintenance
Descaling the Unit
Descaling, also known as flushing, is one of the most important steps in tankless water heater maintenance. It involves running a descaling solution through the unit to remove mineral buildup. This helps maintain efficiency and prevents damage to the heat exchanger. Learn more about descaling tankless water heaters:
Cleaning the Air Filter
Tankless water heaters have air filters that can become clogged over time. Regularly cleaning or replacing the air filter helps maintain proper airflow, ensuring that the unit functions efficiently.
Inspecting the Burner
The burner should be inspected annually to ensure that it is operating correctly. A professional plumber can check for any signs of wear or damage and make adjustments as needed to keep the burner functioning properly.
Checking for Leaks and Corrosion
A thorough inspection should also include checking for any leaks or signs of corrosion. Identifying these issues early can help prevent more serious problems down the line.
DIY vs. Professional Maintenance
Some maintenance tasks, like cleaning the air filter, can be done by homeowners. However, more complex tasks like descaling and burner inspection are best left to a professional plumber. Professional maintenance ensures that all components of your tankless water heater are thoroughly checked and serviced, reducing the risk of damage or breakdowns.
Signs Your Tankless Water Heater Needs Maintenance
Fluctuating Water Temperature:
If you’re experiencing inconsistent water temperatures, it may be due to mineral buildup affecting the heat exchanger.
Reduced Water Flow:
A decrease in hot water flow can indicate a blockage or buildup in the unit that needs to be addressed.
Strange Noises:
If your tankless water heater is making unusual noises, such as gurgling or popping, it could be due to mineral deposits or other internal issues.
Error Codes:
Modern tankless water heaters often display error codes when there’s an issue. If you see an error code, consult your user manual or contact a professional.
FAQs on Tankless Water Heater Maintenance
What maintenance is required on a tankless water heater?
Maintenance on a tankless water heater typically includes descaling to remove mineral buildup, cleaning or replacing the air filter, inspecting the burner, and checking for leaks or corrosion.
What happens if you don’t service your tankless water heater?
If you don’t service your tankless water heater, mineral buildup can reduce efficiency, increase energy costs, and lead to potential damage to the heat exchanger. Neglecting maintenance can also shorten the lifespan of the unit and increase the risk of unexpected breakdowns.
Are tankless hot water heaters high maintenance?
Tankless water heaters are not necessarily high maintenance, but they do require regular servicing to function efficiently. Most units only need professional maintenance once a year, although more frequent descaling may be needed in areas with hard water.
What is the downside of a tankless water heater?
One downside of a tankless water heater is the initial cost, which can be higher compared to traditional tank heaters. Additionally, they require regular maintenance to prevent mineral buildup, and some models may struggle to provide hot water simultaneously to multiple fixtures in large households.
