Condensing Tankless Repair in Hendersonville, TN
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 checked for slope and sagging.

Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems. BGV Plumbing provides specialized Navien tankless water heater repair in Hendersonville, addressing common problems like ignition failures or condensate drain blockages. Our team is familiar with Navien's parts and troubleshooting protocols, delivering a precise and effective repair that maintains your unit's high efficiency.
Ignition Failure Repair in Hendersonville, TN
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 reliably.
Tankless Water Heater Error Code Diagnostics in Hendersonville, TN
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Hendersonville, TN are trained to interpret these codes accurately, using dedicated diagnostic tools to pinpoint the exact component failure. This precision allows us to quickly order the correct parts and perform targeted repairs, saving you time and money. We address codes related to burner failures, fan issues and temperature sensor errors, and more.
Tankless Water Heater Descaling Service in Hendersonville
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Mineral buildup from harder water can wear out water heaters and leave scale on faucets, showerheads and dishwasher parts. Our descaling service in Hendersonville involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.
Recirculation Pump Repair in Hendersonville
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 Descaling and Flushing in Hendersonville
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting 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.
