Are you tired of the inefficient and bulky traditional water heater tanks?

What Are Tankless Water Heaters?

Before delving into maintenance specifics, let us tell you some basics of tankless water heaters.

There are generally two main types of tankless water heaters; the first one is gas tankless water heaters that use propane or natural gas to heat water as it flows through a heat exchanger. On the other hand, condensing tankless water heaters are advanced models that capture and utilize the heat from flue gasses, further increasing their energy efficiency. Both water heater types are purchased, but it is important to know your lifestyle, needs, and budget before you buy a tankless water heater for your home or office.

Essential Tankless Water Heater Maintenance Tasks

Let’s now review the essential maintenance tasks for a tankless water heater. These tasks include cleaning the air filter, inspecting for leaks, and more. Let’s delve into the details of water heater maintenance to make sure that everything is covered.


Inspecting for Leaks

To avoid any water damage and keep your home or commercial building in tip-top shape, it’s important to regularly check for leaks around your water connections, valves, drain pipes, etc. You should always Keep an eye out for any dripping, unusual sounds, or dampness that might suggest a leak. If you spot a leak, it’s best to call a qualified plumber ASAP to resolve the issue before it worsens. Don’t wait until it’s too late.


Cleaning the Air Filter

Did you know that tankless water heaters come with a built-in air filter? This filter keeps dust and debris from getting into your unit, which causes all sorts of problems. To keep your water heater running smoothly, you should check the owner’s manual for the specific location of your air filter and cleaning instructions for your particular model. Generally, you should clean your air filter every 1-3 months, depending on your home’s environment.


Cleaning the Water Filter

Tankless water heaters have water filters, similar to air filters, that capture sediment and other impurities from the incoming water supply. However, if the water filter becomes clogged, it reduces water flow and damages the heat exchanger. Therefore, you should always consult your owner’s manual to locate the filter and follow the recommended cleaning instructions. 


The frequency of cleaning your tankless water heater filter depends on the quality of your water. Still, typically, it is recommended to clean the water filter every 3-6 months to get the maximum performance of your tankless water heater.


Flushing the System 

Mineral deposits accumulate in your tankless water heater over time, reducing the amount of hot water it produces and making it less efficient. To prevent this, it is suggested that these deposits be flushed out regularly. Depending on how hard the water is in your area and the manufacturer’s recommendations, you must flush your water heater every 1-2 years. You should never attempt to flush your water heater on your own unless you are an expert, have training, and have the proper tools. If you do it wrong, you can damage the unit and void the warranty. It’s best to hire a professional plumbing technician with the knowledge and equipment to do it safely.


Checking the Purge Port Valve Caps

Another essential tankless water heater maintenance task is checking the purge port valve caps. Condensing tankless water heaters come with purge port valve caps that gather condensation from the gasses. You must drain these caps regularly to prevent overflow and harm to the unit. To locate these caps and learn how to drain them in the right way, refer to the owner’s manual. If you can’t do it on your own, it is best to hire a professional plumber for this maintenance task.


Annual Professional Tankless Water Heater Maintenance 

To guarantee the best performance of your tankless water heater, you should perform regular maintenance tasks like flushing the system and checking for leaks. Scheduling an annual inspection by a certified plumber is highly recommended to keep your tankless water heater in top condition. 


During the annual inspection, the plumbing technicians thoroughly check the entire water heater system, including the electrical components, heat exchanger, burner, and safety features. By examining these components, the plumber identifies potential problems early on, preventing costly repairs and ensuring efficient operation of your tankless water heater. 


The plumbing team generally starts by examining the heat exchanger responsible for heating the water. They inspect the heat exchanger for signs of scaling, corrosion, or other damage that can impact its performance. The plumbing technicians also check the burner to ensure that it is clean and free of debris. 


Next, the plumber will examine the electrical components of the tankless water heater, including the wiring and control board, and will check for any signs of wear and tear or loose connections that may indicate a potential problem. 


Finally, the professional plumber will examine the safety features of the tankless water heater, such as the automatic shut-off switch and pressure relief valve. They will also confirm that these safety features are working correctly and that they will activate in an emergency. 


When you schedule an annual inspection from a professional plumbing company, you can rest assured that your water heater system is operating efficiently and that any possible problems are pinpointed and fixed right on time. This saves you money on costly repairs and guarantees the reliable operation of your tankless water heater for years to come.
