The Brandson chimney fan increases the performance of your stove - without additional energy consumption. Increase the efficiency of your stove with the Brandson chimney fan - at no extra cost. The innovative fan does not require an external power supply as it is equipped with a thermoelectric module. This module drives the electric motor, which starts operating at a minimum temperature of 50°C. The optimum operating range extends from 80° to 250°C. With an air flow rate of around 300 cubic metres per hour, you will be enjoying the tangible benefits of this system in no time at all. Please note: The surface temperature may be too low for stoves with a natural or soapstone cladding. We therefore recommend that you measure the temperature on the surface in advance - ideally it should reach 50°C or more.
