The standard version operates with electromechanical boiler control and manual ignition and is suitable for single- and two-family homes as well as for modernizing existing heating systems. As a guideline, the output class can be roughly assigned to an area of 200 to 300 m² for suitable building and system configurations; the building\u0026#39;s heat load remains decisive for the specific sizing.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe GSE series operates on the wood gasification principle with a ceramic combustion chamber and induced draft fan. The DC25GSE offers a rated heat output of 25 kW, a boiler efficiency of 92.5%, and energy efficiency class A+. The fuel shaft holds 120 liters and accommodates split logs up to 530 mm in length. The standard control operates the boiler electromechanically; an automatic ignition device is not included in this version.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe large fuel chamber allows the use of long logs and reduces the effort required for fuel preparation. The induced draft fan supports controlled combustion, while the ceramic combustion chamber is designed for the typical post-combustion of wood gas in gasification boilers. After the burn-out, the fan can be switched off via the existing thermostat control.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe DC25GSE is designed for operation with a buffer tank and return temperature raising. Based on the requirement of at least 55 liters of buffer volume per kW of boiler output, this results in a calculated 1,375 liters for 25 kW. For the output class of 20 to 25 kW, a buffer volume of 1,500 to 2,000 liters is planned, so at least 1,500 liters should be assumed for practical system planning. The return temperature to the boiler must be at least 65 °C. Integration can be achieved, for example, via a Laddomat 22 or a correspondingly designed thermostatic valve or mixing solution.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e
