Combustion operates on the wood gasification principle with underfire combustion and is designed for natural log wood. The six-section cast iron boiler body is manufactured in Germany. For the 30 kW version, IBC specifies a recommended living space of 120 to 350 m²; this information serves as an initial guide and does not replace a professional heat load calculation.\u003c\/p\u003e\u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e\u003cp\u003eThe combustion control works with a lambda sensor and modulating primary and secondary fans. The 4.3-inch touch control panel clearly displays boiler operation, buffer tank charging, and relevant operating states. The control manages the buffer tank circulation pump and features residual heat utilization. The 120-liter filling chamber is designed for log wood up to 500 mm in length. Turbulators in the heat exchanger channels support heat transfer and facilitate regular cleaning.\u003c\/p\u003e\u003ch2\u003eEveryday Benefits\u003c\/h2\u003e\u003cp\u003eThe cast iron sectional construction combines a robust boiler design with good heat storage. The large filling door and spacious filling chamber make loading log wood easier. The lambda control adjusts primary and secondary air to the combustion process, while the touch control centrally consolidates essential system states. The door hinge is standard on the right and can be converted to left as an ordering option.\u003c\/p\u003e\u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe GK-7K öko 30 can be integrated into a central heating system as the main heat generator or together with other heat generators such as pellet, oil, or gas heating, or a heat pump. For this output size, a minimum buffer tank volume of 1,650 liters is specified. Hydraulics, return temperature raising, chimney, and safety devices must be matched to the specific system concept.\u003c\/p\u003e\u003ch2\u003eTechnical Data at a Glance\u003c\/h2\u003e\u003cp\u003eNominal heat output30 kW FuelNatural log wood Combustion technologyWood gasification with underfire combustion Efficiency at full load91.44% Energy efficiency classA+ Energy efficiency index119 Seasonal space heating energy efficiency81% Log wood lengthup to 500 mm Boiler class5 Required draft10 Pa Flue pipe connection160 mm Boiler connection flow\/return1 1\/2 inches Max. operating pressure3 bar Lambda sensorYes Buffer tank recommendedYes Minimum buffer tank volume1,650 liters Electrical connection230 V \/ 50 Hz Dimensions H × W × D1,224 × 832 × 1,205 mm Weight700 kg\u003c\/p\u003e\u003ch2\u003eAssembly\u003c\/h2\u003e\u003cp\u003eInstallation, hydraulic integration, electrical installation, and commissioning must be carried out by qualified professionals. Before installation, the suitability of the chimney for the boiler must be checked. The boiler must be integrated into the heating system with a sufficiently sized buffer tank and a suitable return temperature raising system. For closed systems, safety heat exchangers and thermal drain safety devices must be provided in accordance with the system concept and safety requirements.\u003c\/p\u003e\u003ch2\u003eNotes\u003c\/h2\u003e\u003cp\u003eFor reliable wood gasification operation, suitable dry, untreated split logs must be used. The filling chamber, combustion chamber, heat exchanger areas, turbulators, and flue gas paths must be regularly inspected and cleaned.
