Commercial Tankless Water Heater Repair in Dearborn Heights
Commercial tankless water heaters in Dearborn Heights face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the importance of maintaining hot water availability. Our commercial tankless water heater repair services address larger capacity units, complex manifold systems and often more severe scaling issues. We prioritize fast, efficient service to minimize disruption to your business operations.
Flow Sensor and Thermistor Repair in Dearborn Heights
Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are accurate.
Tankless Water Heater Descaling Service in Dearborn Heights
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Lake-sourced municipal water in Michigan is moderately hard, so scale gradually builds up in water heaters and fixtures. Our descaling service in Dearborn Heights involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.
Recirculation Pump Repair in Dearborn Heights
Many tankless systems use internal or external recirculation to deliver hot water faster. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your routine. A properly tuned system saves both water and gas.
Ignition Failure Repair in Dearborn Heights, MI
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Condensing Tankless Repair in Dearborn Heights, MI
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also inspected for slope and sagging.

Frequently Asked Questions About Tankless Water Heater Repair in Dearborn Heights
Most tankless repairs cost between $175 and $600, depending on the part. Descaling service often runs $175 to $350, while heat exchanger replacement can exceed $800 if not under warranty. We quote before any work begins.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require specialized tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a professional.
Error codes can be triggered by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code points to a specific system malfunction.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a few years.
Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also significantly reduce mineral buildup in areas with very hard water.
Frequent causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent many of these problems.
Regular maintenance, particularly annual descaling, is crucial for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues early.
