A new boiler – Unica Sensor Bio – is now available in our offer. It is a universal set for burning solid fuel such as coal, pellets. The set consists of UNICA Sensor boiler, an universal burning head with an automatic fuel feed system, an igniter and a tank. Its universality is possible due to the head that can be detached ( quick assembly and disassembly) and a classic construction of UNICA Sensor that allows for manual feeding. It is the boiler of high efficiency in which variety of fuel can be effectively burnt. Unica Sensor Bio’ advantage is its charge flap placed at an angle that covers a wide opening through which long logs can be loaded in a large combustion chamber. In the frame of igniting door a burner for burning pellets has been installed; such solution allows for burning various fuel, facilitates cleaning the head and above all, it answers the eternal question: “what to burn with”. The igniter fixed in the head reduces the time of device handling to minimum.
