Emergency Tankless Repair in Burlington
A tankless unit that leaks internally or shows a fault you cannot clear needs quick attention. We prioritize no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meantime.

Tankless Descaling and Flushing in 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 wise for most homes on hard water.
Tankless Water Heater Error Code Diagnostics in Burlington, VT
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Burlington, VT 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.
Gas Tankless Water Heater Repair in Burlington
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors. Our certified technicians in Burlington perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Tankless Water Heater Descaling Service in Burlington
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Some Vermont wells carry iron, manganese or other naturally occurring minerals, so a water test is the first step before choosing treatment. Our descaling service in 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.
Flow Sensor and Thermistor Repair in Burlington
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.
Recirculation Pump Repair in Burlington
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.

Electric tankless units offer a compact solution but can run into problems with heating elements or circuit breakers.
