Boiler Flue Temperature Sensor Replacement in Greater Vancouver
Monitors exhaust temperature for safety and efficiency. Supplied and professionally installed by licensed gas fitters — never sold for DIY.
What the Flue Temperature Sensor Does
The flue (exhaust) temperature sensor watches the temperature of gases leaving the boiler. Abnormal readings indicate a blocked or failing heat exchanger, scaling, or venting issues, and will trigger a protective shut-down.
A thermistor in the flue path feeds exhaust temperature to the control board, which uses it to protect the heat exchanger and confirm the boiler is condensing efficiently.
We supply and fit the flue temperature sensor as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
