Heating with all the comfort
The Kalorina 21 series wood-burning boiler has a refractory fire top with grate and a large combustion chamber for a clean and efficient combustion.
The large door allows you to load wood in logs, wood briquettes or wood waste up to 50 cm long, ensuring long hours of operating autonomy.
Prepared for gas oil functioning
The Kalorina 21 series wood-burning boiler offers all the advantages of biomass boilers, but is also designed for the installation of a burner for oil-fired operation; the system is perfect for those who cannot guarantee manual feeding with wood or during periods of long absence.
Cleaning and practicality
The exchange surfaces and the combustion chamber can be easily cleaned thanks to the supplied kit. For the removal of ash there is a special ash tray that is easily accessible; a mechanical lever system on the boiler side removes the ashes from the flue gas chamber.
The KALORINA 21 series wood-fired boiler can be easily regulated and allows a practical boiler management in all phases of operation through the temperature thermostat and the air damper, which can be constantly adjusted to optimize ignition and combustion.
