Electric Tankless Water Heater Repair in South Burlington, VT
Electric tankless units offer a compact solution but can encounter problems with heating elements or circuit breakers. CKV Plumbing offers expert electric tankless water heater repair in South Burlington, VT, addressing electrical faults, ensuring proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Tankless Descaling and Flushing in South Burlington
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.
Navien Tankless Water Heater Repair in South Burlington
Navien units are known for their advanced condensing technology but can sometimes experience issues with their circulation pump or exhaust systems.

For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in South Burlington, VT diagnoses issues with igniters, flame sensors and gas valves.

Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.
Gas Tankless Water Heater Repair in South Burlington
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our certified technicians in South Burlington perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Flow Sensor and Thermistor Repair in South Burlington
Tankless heaters rely on 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 South Burlington
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. A large share of Vermont homes rely on private wells, and well water here can range from soft to moderately hard depending on the bedrock. Our descaling service in South Burlington 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.
Condensing Tankless Repair in South Burlington, VT
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.
