Gas Tankless Water Heater Repair in Brattleboro
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 Brattleboro perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Flow Sensor and Thermistor Repair in Brattleboro
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 faulty parts. Temperature becomes steady again once readings are accurate.
Tankless Water Heater Error Code Diagnostics in Brattleboro, VT
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Brattleboro, VT are trained to interpret these codes accurately, using dedicated diagnostic tools to pinpoint the exact component failure.

Pilot Light and Ignition Repair in Brattleboro, VT
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Brattleboro, VT diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.
Ignition Failure Repair in Brattleboro, VT
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.

Tankless Descaling and Flushing in Brattleboro
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.
