The output range from 3.3 to 11.0 kW allows the heat output to be adapted to the current demand of the heating system.\u003c\/p\u003e\n\u003cp\u003eWood pellets are used as fuel. The SmartFire SF11 can be used both for building heating and in conjunction with domestic hot water preparation. For pellet storage, three storage containers with capacities of 150, 240, or 440 liters are available.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"gema-section\"\u003e\n\u003ch2\u003eTechnology \u0026 Equipment\u003c\/h2\u003e\n\u003cp\u003eThe GEMA Automatic version combines the SmartFire SF11 with a lambda sensor, automatic heat exchanger cleaning, and automatic ash removal. In addition, there is the automatic stainless steel pellet burner, automatic mechanical burner cleaning, and automatic ignition.\u003c\/p\u003e\n\u003cp\u003eThe lambda sensor supports the control of the combustion process by measuring the residual oxygen content in the flue gas. The motor-driven heat exchanger cleaning reduces the regular manual cleaning effort of the heat exchanger.\u003c\/p\u003e\n\u003cp\u003eFor fuel supply, the boiler works with a screw conveyor and a backburn protection flap. The control system also handles functions of the heating system in addition to boiler operation and is operated via a touch control panel.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"gema-section\"\u003e\n\u003ch2\u003eAutomatic Ash Removal\u003c\/h2\u003e\n\u003cp\u003eIn the Automatic version, the ash produced in the boiler is automatically transported via two screw conveyors into a laterally arranged ash container. In the container, the ash is compacted, which can significantly extend the required emptying intervals compared to a classic ash box.\u003c\/p\u003e\n\u003cp\u003eIn the versions with 150, 240, and 440 liter storage containers, the ash container is located to the left of the boiler. This increases the overall width of the system compared to the standard version.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"gema-section\"\u003e\n\u003ch2\u003eEveryday Benefits\u003c\/h2\u003e\n\u003cp\u003ePellet feeding, ignition, burner cleaning, heat exchanger cleaning, and ash removal run largely automatically in the Automatic version. This significantly reduces the regular operating and cleaning effort compared to the standard version.\u003c\/p\u003e\n\u003cp\u003eThe three available container sizes allow adaptation to different space conditions and desired pellet supplies.
