It typically costs about $150 to $800, though the average tends to be around $600 to fix a tankless water heater. Tankless water heaters require periodic flushing of minerals and sediment to keep them from building up inside the unit. If these maintenance procedures are neglected, you’ll likely run into water heater issues that will need to be repaired by one of our plumbers.
While tankless water heaters require significantly less repairs than storage tank water heaters, they can still encounter problems that will require a professional’s skill set to repair. When and if issues arise, lean on Biagi Plumbing. Our team of expert plumbers will get your tankless water heater repaired in no time!
Your tankless water heater could stop working for a plethora of reasons; a plugged heat exchanger due to hard water, a blocked vent and air intake, or running too many hot water appliances at once. Tankless water heaters only heat water as needed, so running multiple appliances that require hot water can overwhelm your system and cause it to stop working. If your tankless water heater does stop working, call (847) 512-8921 to have an expert help resolve the problem.
Common issues with tankless water heaters range from air supply and exhausts getting blocked (which can cause the device to shut down), the pilot light failing to ignite, sensors quitting at random, and more. It’s important to have one of our certified technicians repair your tankless water heater as trying to do it yourself could potentially void the warranty or cause further damage.
Tankless water heaters do rely on gaskets, seals, and other components that can wear out over time. Generally, an annual maintenance service will include an inspection of these components and allow the opportunity to replace them when they start to show signs of wear or failure. However, if you do find water leaking from your system, don’t be alarmed. Simply call a repair technician at Biagi Plumbing to take a look at the issue for you.
Common culprits of water heater issues include a buildup of sediment in the system, a clogged filter, or a problem with the heating element. Over time, sediment can accumulate, especially in areas with hard water, reducing the efficiency of your unit. This is why regular maintenance from Biagi Plumbing is essential for keeping your system running efficiently. With cooler fall weather setting in, it’s more important than ever to address any problems if your unit is failing to provide hot water. Biagi Plumbing is here to help with professional repairs to ensure your tankless water heater is functioning properly and reliably.
It depends on the issue’s severity, the unit’s age, and its overall condition. Minor problems, such as clogged filters or faulty sensors, can often be addressed quickly and affordably, making repairs a practical option for newer systems still within their expected lifespan. On the other hand, if your unit is experiencing recurring issues, reduced efficiency, or is approaching the end of its usable life, replacing it may ultimately prove to be the more cost-effective and reliable solution. At Biagi Plumbing, our experts are here to give you honest advice, helping you decide whether repairing your current tankless water heater or upgrading to a new one is the best choice for your situation.
Unusual noises coming from your tankless water heater—such as clicking, banging, or hissing—could indicate trapped air, pressure imbalances, sediment buildup, or even faulty components. While these sounds may seem minor, ignoring them can lead to reduced performance, higher energy bills, or costly damage over time. Don’t wait for small issues to become major repairs—fall is the perfect time for a check-up before colder weather puts extra demand on your system.
Low water pressure is often caused by clogged pipes, a faulty pressure regulator, or mineral buildup inside your tankless water heater. Since these issues develop gradually, you might not notice them until your water pressure drops significantly. Addressing the problem early not only restores proper water flow but also helps prevent unnecessary strain on your plumbing system. Fall is the perfect time to have a Biagi Plumbing expert inspect your system and ensure your home is ready for the colder months ahead.
When you turn on the hot water tap, your tankless water heater must detect the water flow, ignite the burner, and heat the water to your desired temperature before it reaches your faucet. Depending on the distance your water has to travel, you may experience a slight delay—this is completely normal. However, there are ways to speed up hot water delivery. Installing a recirculation pump or insulating your pipes can help reduce wait times and improve efficiency. Our Biagi Plumbing experts can assess your home’s setup and recommend the best solutions for faster, more reliable hot water.
