Tankless water heaters are becoming increasingly popular due to their energy efficiency and ability to provide hot water on demand. Unlike traditional tank-style water heaters, tankless models heat water directly as it flows through the system, which eliminates the need for a bulky storage tank. While these units are known for their longevity and reliability, they are not immune to issues that could lead to costly repairs if not properly maintained. Proper care and preventative maintenance can save you from expensive repair bills and extend the lifespan of your tankless water heater. In this blog, we’ll explore some essential tips and practices to help you avoid costly repairs and keep your system running smoothly.
1. Regularly Flush the System to Prevent Mineral Buildup
One of the most common issues faced by tankless water heater repair is the buildup of mineral deposits, especially in areas with hard water. Over time, minerals like calcium and magnesium accumulate in the heat exchanger, which can cause the unit to overheat, become less efficient, and eventually break down. To prevent this, it’s essential to flush your tankless water heater regularly.
Why it’s important: Mineral buildup in the heat exchanger can obstruct water flow, reduce heating efficiency, and cause overheating. This not only increases energy consumption but also puts a strain on the unit, which could lead to costly repairs.
How to do it: Flushing your tankless water heater typically requires a descaling solution and a few basic tools. Many manufacturers recommend flushing the system every 12 months. However, in areas with hard water, you may need to flush it more frequently (every 6 to 9 months). If you're unsure about how to do this, consult the user manual or contact a professional plumber.
2. Keep the Air Supply and Exhaust Venting Clean
Tankless water heaters require proper venting to function efficiently and safely. Air supply and exhaust vents ensure that the unit receives enough fresh air for combustion and expels harmful gases like carbon monoxide. Over time, dirt, debris, and even pests can clog the vents, which could result in poor airflow, inefficient operation, and potential damage to the system.
Why it’s important: Blocked vents can lead to poor combustion, which increases wear and tear on the unit and reduces its lifespan. In extreme cases, it could even cause dangerous situations like carbon monoxide buildup in your home.
How to do it: Inspect the venting system regularly, especially before and after extreme weather conditions like heavy rains or snowstorms. Ensure the vents are clear of any obstructions such as leaves, bird nests, or debris. If your tankless water heater uses a direct venting system, check both the intake and exhaust vents for blockages. Clean the vents as needed, and consider hiring a professional for a more thorough inspection.
3. Set the Water Temperature to a Safe Level
Many homeowners set their tankless water heater’s temperature to a higher-than-necessary level, thinking it will improve the hot water output. However, this can put undue stress on the system, increase energy costs, and potentially damage the unit over time. Keeping your water heater at an optimal temperature can prevent these problems.
Why it’s important: Setting the temperature too high can cause unnecessary strain on the heating elements and increase the chances of scaling and overheating. Conversely, setting the temperature too low may result in an insufficient hot water supply. The recommended temperature for most households is around 120°F (49°C).
How to do it: Check the settings on your tankless water heater to ensure it is set to a safe and efficient temperature. If you’re unsure, refer to the manufacturer’s recommendations or consult a professional plumber. Avoid constantly adjusting the temperature, as this can stress the unit and cause erratic performance.
4. Install a Water Softener
If you live in an area with hard water, it’s a good idea to install a water softener. Hard water can significantly reduce the efficiency of your tankless water heater by causing scale buildup inside the unit. Installing a water softener will reduce the mineral content in the water, preventing deposits from forming in the heat exchanger and pipes.
Why it’s important: Water softeners reduce the chances of mineral buildup, which can lead to costly repairs and a shorter lifespan for your tankless water heater. It also improves the overall performance of the unit and enhances its energy efficiency.
How to do it: Consult with a water treatment specialist to determine the best type of water softener for your needs. While water softeners do require some maintenance, they can significantly extend the life of your tankless water heater by preventing mineral damage. Regularly check the softener to ensure it’s functioning properly.
5. Inspect and Clean the Filters Regularly
Many tankless water heaters come equipped with filters that help prevent debris and sediment from entering the system. Over time, these filters can become clogged, restricting water flow and potentially causing damage to the unit. Cleaning the filters regularly is a simple yet effective way to maintain your tankless water heater’s performance.
Why it’s important: A clogged filter can cause a reduction in water flow, which puts strain on the system and can lead to overheating or other malfunctions. Keeping the filter clean ensures that water flows freely through the unit, preventing unnecessary wear and tear.
How to do it: Consult your user manual to find out where the filter is located and how to remove it. In most cases, you can clean the filter by rinsing it with water. Some filters may require periodic replacement, so keep an eye on the condition of the filter and replace it when necessary.
6. Schedule Annual Professional Inspections
Even if you follow all the maintenance tips above, it’s still a good idea to schedule a professional inspection of your tankless water heater every year. A licensed plumber can perform a thorough inspection, check for any early signs of wear and tear, and address potential issues before they become major problems.
Why it’s important: While regular DIY maintenance is essential, some issues may not be easily detectable without professional expertise. An experienced plumber can catch potential problems early, saving you from expensive repairs down the line. Additionally, annual inspections ensure that the unit is operating at peak efficiency.
How to do it: Find a reputable plumber who specializes in tankless water heaters and schedule an annual service. This may include a full inspection, flushing the system, cleaning the filters, and checking for any worn-out components that need replacing.
7. Address Issues Immediately
Finally, if you notice any signs of trouble with your tankless water heater, such as strange noises, fluctuating water temperatures, or a decrease in hot water flow, don’t wait to address the issue. Early detection and prompt repairs are crucial to preventing small problems from turning into expensive repairs.
Why it’s important: Ignoring early signs of malfunction can lead to more serious damage, which could ultimately require the replacement of expensive parts or even the entire unit. By addressing issues as soon as they arise, you can minimize the impact on your wallet and extend the lifespan of your tankless water heater.
How to do it: If you notice any unusual behavior, consult the user manual for troubleshooting tips or call a professional plumber for advice. Don’t wait until the issue worsens.
Conclusion
Tankless water heaters are an excellent investment, offering energy efficiency and consistent hot water. By following these preventative maintenance tips, you can avoid costly repairs and keep your unit running smoothly for years to come. Regularly flushing the system, cleaning filters, checking vents, and addressing issues early can save you time and money in the long run. With proper care and attention, your tankless water heater will continue to provide you with reliable hot water when you need it most.
