It is suitable as a central heat source for heating systems in residential buildings, holiday homes, small businesses, and comparable properties when a biomass heating system with flexible fuel use is planned.\u003c\/p\u003e \u003cp\u003eIn wood operation, the boiler works on the principle of wood gasification. For pellet operation, a pellet burner is provided that enables operation with wood pellets. The boiler output must be matched to the heating load and the planned system configuration.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe combination boiler is designed for split logs and wood pellets, but not for simultaneous operation with both fuels. In wood operation, combustion takes place according to the gasification principle with an induced draft fan, while in pellet operation the pellet burner handles fuel supply, ignition, and combustion.\u003c\/p\u003e \u003cp\u003eEquipment includes a PROFI-PID controller, a flue gas heat exchanger with turbulators, a water-cooled boiler body, and a pellet burner on a pantograph arm. The controller monitors key operating values and can control, among other things, the heating circuit and the domestic hot water or buffer tank charging pump.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe Attack SLX 35 COMBI Pellet combines manual wood firing with the more convenient pellet operation in a single boiler. The large loading chamber makes wood operation easier, while pellet operation reduces the effort required compared to pure log wood firing.\u003c\/p\u003e \u003cp\u003eThe display of operating states, fault diagnosis, and structured control support clear operation. For long-term stable operation, professional installation, suitable fuel, regular maintenance, and clean hydraulic integration remain crucial.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe combination boiler is integrated into water-based heating systems and requires suitable return temperature raising to ensure the required return temperature is maintained. In wood operation, integration with a buffer tank is intended; in pure pellet operation, the system logic may differ and must be planned accordingly.\u003c\/p\u003e \u003cp\u003eFor pellet operation, a suitable pellet container and a screw conveyor are required. The chimney, safety valve, thermal drain safety device, hydraulic integration, and electrical connections must be designed according to the applicable regulations and the specific installation situation.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0 1rem}.product-th__table{width:100%;border-collapse:separate;border-spacing:0}.product-th__table td{padding:.95rem 1rem;vertical-align:top}.product-th__label{font-weight:700;width:38%;color:#213670}.product-th__value{color:#1f2937}.product-th__table tr:nth-child(odd) td{background:#f4f7fb}.product-th__table tr:nth-child(even) td{background:#fafbfd} \u003c\/style\u003e \u003cdiv class=\"product-th\"\u003e \u003ch2\u003eTechnical data at a glance\u003c\/h2\u003e \u003cp\u003eThe following values summarize the confirmed key data of the Attack SLX 35 COMBI Pellet.\u003c\/p\u003e \u003ctable class=\"product-th__table\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eNominal output\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e35 kW wood \/ 30 kW pellets\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eFuel\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eFirewood and wood pellets\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eCombustion technology\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eWood gasification \/ pellet operation\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eEfficiency\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e90.3% wood \/ 90.6% pellets\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eBoiler class\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e5\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eMax. flow temperature\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e90 °C\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eMax. operating pressure\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e2.5 bar\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eLog length\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e650 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eDraft requirement\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e23 Pa\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eFlue gas temperature\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e170 °C wood at minimum output \/ 148 °C pellets at rated output\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eFlue pipe connection\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e150 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eSafety heat exchanger\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eAfter-cooling circuit integrated\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eHeight\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e1472 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eWidth\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e703 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eDepth\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e1650 mm with burner\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eVoltage \/ Frequency\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e230 V \/ 50 Hz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003ePower consumption\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e42 W wood \/ 190 W pellets \/ 600 W at ignition\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eWeight\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e610 kg\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eAssembly\u003c\/h2\u003e \u003cp\u003eThe installation of the boiler should be carried out by a qualified specialist company based on local requirements and the manufacturer\u0026#39;s documentation.
