Flue gas thermostat 50-300°C for automatic pump control

Efficient temperature control with the flue gas thermostat 50-300°C

The flue gas thermostat (50-300°C) is the ideal solution for optimizing the operation of your heating system. This thermostat ensures precise control of the charging pump between the boiler and expansion vessel. It simplifies the heating process, saves energy, and extends the lifespan of your heating system through optimally regulated temperatures.

Function and advantages of the flue gas thermostat

The flue gas thermostat performs the important task of automatically switching on the pump as soon as the flue reaches the set operating temperature. This prevents cold water from reaching the bottom of the boiler too early and cooling it unnecessarily. Your boiler thus reaches its optimal operating temperature more quickly, significantly increasing efficiency.

Once the combustion process is complete, the thermostat automatically stops the pump as soon as the flue has cooled down. This not only saves energy but also preserves the thermal stratification in the buffer storage tank, resulting in a significantly higher energy yield.

Avoiding unwanted energy losses

Using only a water thermostat can lead to inefficient energy losses. However, the 50-300°C flue gas thermostat ensures better energy management. For example, if the boiler and buffer tank are heated to 90°C, the flue gas thermostat maintains the thermal stratification within the tank. This prevents the loss of 30% of the stored energy through unnecessary cooling, which would otherwise escape through the chimney.

Easy installation of the flue gas thermostat

The flue gas thermostat and its associated sensor are easy and safe to install. The sensor is securely attached to the outside of the flue. Using the included mounting kit, the sensor can be installed stably without being directly exposed to the flue gas. For top-fired boilers, where the sensor temperature can exceed 300°C, the use of spacers is recommended.

Thanks to its well-designed construction, the thermostat can be installed near the power switch, allowing for short and safe cable routing. When connecting to boilers without automatic circulation, the installation of an additional water thermostat is recommended to ensure maximum safety and operational efficiency.

Robust housing and technical details

The housing of the flue gas thermostat is made of heat-resistant plastic, protecting it from damage caused by heat radiation. This ensures a long service life and reliable operation even in challenging environments. A changeover contact and a 1.5 m long capillary tube allow for flexible installation.

The device offers precise temperature control in the range of 50-300°C, a resistance load of 16 A at 250 V, and mounting options for external smoke ducts. With a sensor length of 160 mm and a diameter of 3 mm, the thermostat is both compact and powerful, and universally applicable.
