With a nominal output of 20 kW and an output range of 10 to 20 kW, it is suitable for heating systems whose heat demand has been professionally matched to this output.\u003c\/p\u003e \u003cp\u003eThe 200-liter filling chamber accommodates split, dry firewood with a length of up to 650 mm. The generously sized fuel chamber supports longer burn phases and reduces the amount of operator effort compared to boilers with smaller filling chambers.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe LAMBDA Touch control system records boiler temperature, flue gas temperature, and residual oxygen content. On this basis, the induced draft fan and the motor-operated primary and secondary air dampers are regulated. This allows the combustion air to be automatically adapted to the respective operating state.\u003c\/p\u003e \u003cp\u003eA tubular heat exchanger with turbulators supports heat transfer to the heating water. The integrated cooling loop or safety heat exchanger, in conjunction with a suitable thermal drain safety device, protects the boiler against impermissibly high temperatures.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe large filling chamber and the maximum log length of 650 mm allow the use of longer logs. With suitable fuel quality and a correctly designed system, an indicative burn duration of up to about eight hours per load is possible at nominal operation.\u003c\/p\u003e \u003cp\u003eThe automatic air control relieves the operator of manual adjustment of primary and secondary air. Touchscreen, lambda sensor, and regulated induced draft fan support controlled and traceable boiler operation.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eFor the ATTACK SLX 20 LAMBDA Touch, a buffer tank with a nominal volume of 1,500 liters is recommended. The final sizing depends on the heating load, system hydraulics, heat draw, and the applicable technical requirements.\u003c\/p\u003e \u003cp\u003eThe boiler has flow and return connections in G 6\/4 inch as well as a flue gas connection with a 150 mm diameter. The required chimney draft is 23 Pa.
