Professional planning is required for the design of the chimney, flue gas pipe, and hydraulics. :contentReference[oaicite:3]{index=3}\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 technical data for the Atmos GS 15 has been reliably verified from the available documents and official manufacturer sources.\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\"\u003e15 kW\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eFuel\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eDry Wood\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eCombustion Technology\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eWood Gasifier with Induced Draft Fan\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eEfficiency\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e91.2 %\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eEnergy Efficiency Class\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eA+\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eMax.

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.

It is intended for water-based heating systems and serves as a heat generator in systems where the generated heat is controlled and distributed via a buffer tank.\u003c\/p\u003e \u003cp\u003eThe Optima HG model series is designed for use with hardwood split logs. The boiler operates on the wood gasification principle, making it an attractive option for operators who want a classic log wood heating system with structured combustion technology.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026 Equipment\u003c\/h2\u003e \u003cp\u003eIn the Defro Optima HG, the wood is degassed in the upper combustion chamber. The resulting wood gases are directed through a combustion nozzle into the lower combustion chamber, where they are burned off. The combustion chambers are lined with fireclay bricks designed for high temperatures in the combustion zone.\u003c\/p\u003e \u003cp\u003eThe flue gases are routed through tubular heat exchangers. Specially shaped turbulators support the heat exchange process. An induced draft fan extracts the flue gases from the boiler, while the electronic control system regulates operation to the set boiler temperature. Standard equipment also includes a safety temperature limiter and an integrated safety heat exchanger.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Advantages\u003c\/h2\u003e \u003cp\u003eThe wide loading door makes it easier to load split logs.

The integrated cleaning mechanism for the heat exchanger supports proper maintenance of the boiler.\u003c\/p\u003e \u003cp\u003eFor ongoing heating operation, it is important that the generated heat is continuously absorbed by the heating system.
