With a nominal output of 40 kW, this model is aimed at applications with higher heat demand where a classic log wood boiler with wood gasification technology, a large fuel chamber, and clear, robust engineering is required.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gema-section\"\u003e\n\u003ch2\u003eTechnology \u0026 Features\u003c\/h2\u003e\n\u003cp\u003eThe boiler operates on the principle of downdraft gasification with an induced draft fan. The combustion air is preheated before being introduced into the combustion chamber, the secondary combustion chamber is equipped with ceramic components, and the boiler has an integrated cooling coil for overheat protection. Features include a thermometer, flue gas thermostat, boiler thermostat for the fan, and mechanical operation of the start-up damper.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gema-section\"\u003e\n\u003ch2\u003eEveryday Benefits\u003c\/h2\u003e\n\u003cp\u003eFor practical operation, the Atmos GS 40 offers a large fuel shaft for logs up to 530 mm in length. This supports longer burn intervals and reduces the frequency of refueling compared to smaller units. The induced draft fan contributes to more even combustion, while the clear electromechanical control logic makes the boiler appealing to users who prefer robust and straightforward technology.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gema-section\"\u003e\n\u003ch2\u003eSystem Integration \u0026 Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe boiler is designed for integration into water-based heating systems. According to the documentation, installation with a buffer tank is mandatory; for the GS 40, the technical specifications state a minimum volume of 750 liters. When used with buffer tanks, benefits include more economical operation, lower fuel consumption, and compatibility with radiators and underfloor heating. For return temperature protection, integration via a Laddomat 22 or a suitable thermostatic control valve is recommended.\u003c\/p\u003e\n\u003c\/div\u003e\n\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\n\u003cdiv class=\"product-th\"\u003e\n\u003ch2\u003eTechnical Specifications at a Glance\u003c\/h2\u003e\n\u003cp\u003eA compact overview of the most important, reliably verified core data for the Atmos GS 40.\u003c\/p\u003e\n\u003ctable class=\"product-th__table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eNominal Output\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e40 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eFuel\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eWood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eCombustion Technology\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eWood Gasification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eEfficiency\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e88.8 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eEnergy Efficiency Class\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eA+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eMax.
