The output range of 20 to 40 kW and the large-volume filling chamber make it particularly interesting for buildings and systems with a correspondingly high, professionally determined heat demand.\u003c\/p\u003e \u003cp\u003eThe intended fuel is dry, split firewood with a moisture content of about 12 to 20 percent. The permissible log length for this size is up to 750 mm. The selection of boiler output does not replace a heat load calculation and must be matched to the building, heat distribution, chimney, and buffer tank.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe boiler operates on the wood gasification principle with an induced draft fan and separately guided primary and secondary air. The filling chamber holds 230 liters. The resulting wood gases are afterburned in the lower combustion chamber, and the heat is then transferred to the heating water via a tubular heat exchanger with turbulators.\u003c\/p\u003e \u003cp\u003eThe PROFI control processes the boiler and flue gas temperatures and adjusts the fan speed to the operating state. In addition, it can control the heating circuit pump and optionally a hot water or buffer tank charging pump. When approaching the set boiler temperature, the output is reduced, and the fan is switched off when the setpoint is reached.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe large filling chamber allows long logs to be loaded and, with a suitable system output, reduces the number of required refills. As a guide value, the SLX 40 is specified with a burn time of about six hours per full load at nominal operation.\u003c\/p\u003e \u003cp\u003eThe externally accessible turbulator lever supports regular cleaning of the heat exchanger flues. This helps reduce deposits and supports heat transfer through the tubular heat exchanger during 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 40 PROFI, a buffer tank with a nominal volume of 3,000 liters is recommended. The final tank size depends on boiler output, system hydraulics, building, and operating mode. Flow and return connections are designed with G 2 inch threads.\u003c\/p\u003e \u003cp\u003eA suitable return temperature control must ensure a return temperature of at least 65 °C. In addition, a sufficiently sized safety valve, a thermal drain safety device on the integrated cooling circuit, appropriate pressure maintenance, and a permanently secured heat dissipation are required.\u003c\/p\u003e \u003cp\u003eThe chimney and flue gas pipe must be designed for a required draft of 23 Pa. The flue gas connection has a diameter of 150 mm.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0
