A flue gas exhaust thermometer should be installed near the base of the breeching near the boiler, to monitor the outgoing temperature of flue gasses. High flue gas temperature is typically an indication of soot build-up in the fireside of the boiler that causes reduced boiler efficiency, corrosion failure of steel, reduced heat transfer rates to the waterside of the unit, draft loss, excessive fan power consumption, and fire hazards.
The temperature of your boiler/burner unit is one indicator that your burner and boiler are operating efficiently or if it requires a fireside cleaning. Therefore, we propose to install/replace a Flue Gas Exhaust Thermometer which would allow the building staff and service personnel to gauge the boiler’s heat absorption and transference at a glance.
