With a nominal output of 55 kW and an output range of 27.5 to 55 kW, this version is intended for larger central heating systems whose heat demand has been professionally matched to the boiler output.\u003c\/p\u003e \u003cp\u003eThe 230-liter loading chamber accommodates dry, split firewood with a length of up to 750 mm. The generously sized fuel chamber allows the use of long logs and reduces the effort required for splitting and reloading the fuel.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe LAMBDA Touch control processes boiler temperature, flue gas temperature, and residual oxygen content. Based on these measured values, it controls the induced draft fan as well as the motorized primary and secondary air dampers. The combustion air and boiler output are thus automatically adapted to the respective operating state.\u003c\/p\u003e \u003cp\u003eTouchscreen, lambda sensor, and air actuators support controlled combustion. A tubular heat exchanger with turbulators improves heat transfer to the heating water. The integrated safety heat exchanger enables the integration of a thermal drain safety device.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe large loading chamber and the maximum log length of 750 mm allow the use of long logs. With suitable fuel quality, nominal operation, and a correctly matched system, the approximate burn time is about four hours per load.\u003c\/p\u003e \u003cp\u003eThe automatic combustion control reduces the need for manual adjustments of the primary and secondary air. Boiler, flue gas, and buffer tank temperatures can be monitored via the touchscreen.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eFor the ATTACK SLX 55 LAMBDA Touch, a buffer tank volume of 4,000 liters is recommended. The final sizing depends on the heating load, system hydraulics, heat draw, operating mode, and the technical requirements of the respective building.\u003c\/p\u003e \u003cp\u003eFlow and return connections are designed as G 2 inch connections. The flue pipe connection has a diameter of 150 mm, and the required chimney draft is 23 Pa. A suitable return temperature boost must ensure a return temperature of at least 65 °C.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0
