Flow Sensor and Thermistor Repair in Paducah
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 faulty parts. Temperature becomes steady again once readings are accurate.

Commercial Tankless Water Heater Repair in Paducah
Commercial tankless water heaters in Paducah face heavier usage and require durable 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.
Tankless Descaling and Flushing in Paducah
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.
Condensing Tankless Repair in Paducah, KY
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 confirm proper drainage. PVC venting is also checked for slope and sagging.
Recirculation Pump Repair in Paducah
Many tankless systems use internal or external recirculation to deliver hot water more quickly. 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 daily routine. A properly tuned system saves both water and gas.
Tankless Repair vs Replacement Cost in Paducah, KY
Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.
Electric Tankless Water Heater Repair in Paducah, KY
Electric tankless units offer a compact solution but can encounter problems with heating elements or circuit breakers.

Ignition Failure Repair in Paducah, KY
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.

Private wells and cisterns still serve some rural homes, and iron, sulfur, and sediment are frequent reasons for water treatment. Tankless heaters scale up when water is hard, so careful repair and regular descaling are what keep these efficient units running for their full lifespan.

Frequently Asked Questions About Tankless Water Heater Repair in Paducah
The cost of tankless water heater repair in Paducah varies widely depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after diagnosing the specific problem.
Regular professional maintenance, including descaling and checking all connections, is the best defense. Installing a whole-home water softener can also greatly reduce mineral buildup in areas with very hard water.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to pinpoint the cause.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still smart.
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.
Yes, BFK Plumbing stands behind its work. All our tankless water heater repairs come with a satisfaction guarantee and a warranty on both parts and labor. We will provide full warranty details with your repair estimate.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a couple of years.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or delicate internal components should always be left to a licensed professional. DIY attempts can be dangerous and cancel warranties.
