A system designed and patented by CS THERMOS 100% Made in Italy.

The innovative multi-fuel burner, the heart of our stoves, allows to burn all types of wood pellets and also wastes from agricultural processing like: agripellet, pelletised vine pruning, coffee ground pellet, chopped or whole olive pits, shells of almonds/walnuts/hazelnuts/apricots pits, cherry pits, wood chips.

The patented CS Thermos System: horizontal auger and self-cleaning, multi-fuel burner
An auger (1) picks up the pellets from the tank, lets them drop along a perfectly vertical pipe (2), and then another horizontal auger (3) pushes them into the dynamic and selfcleaning burner (cast iron wheel 4) where the fire is ignited by 2 heating elements (5) in about 5 minutes. The vertical drop of the pellet and the motor that pushes it along the horizontal auger make sure that the pellet duct (2) is always clear, preventing any possibility of backfire from the fire box to the fuel tank.

Classical structural method
An auger (1) picks pellets from the tank and drops them along the oblique pipe (2) up to the brazier where the fire is lit in approximately 10-15 minutes by only 1 electrical resistor (3).

The CS Thermos Patent

The innovative multi-fuel burner is patented by CS THERMOS (Patent N° EP 2144001B1), and through, the vertical drop of the pellet and the motor that pushes it along the horizontal auger make sure that the pellet duct is always free, preventing any possibility of backfire from the fire box to the fuel tank.
