This version combines the proven GSE wood gasification with an electronic ACD04 control system and a separate ignition chamber with a glow coil. The boiler is suitable for single-family homes and comparable buildings, as well as for modernizing existing heating systems, provided that output, buffer tank, hydraulics, and heat demand are professionally coordinated with each other.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eCombustion takes place according to the principle of generator gasification with a ceramic secondary combustion chamber and induced draft fan. The fuel shaft holds 120 liters and, in the DC25GSE, accommodates split logs up to 530 mm in length. For automatic wood ignition, a removable ignition chamber with a glow coil is integrated between the boiler doors. To prepare for automatic ignition, the ignition chamber is filled with suitable pellets; the boiler\u0026#39;s main fuel remains dry split logs. The electrical power consumption is 50 W in normal operation and 550 W for the ignition system.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe ACD04 control system expands classic split log operation with schedulable automatic ignition. Depending on the system configuration, the start can be prepared according to a schedule, according to buffer tank temperature, or, in systems without a buffer tank, according to a heating system demand. The wood is still loaded manually; the automatic ignition then takes over lighting the prepared fuel. The ACD04 control system also allows control of the heating circuits configured for the respective hydraulics and domestic hot water preparation.\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 integration into a system with a buffer tank and effective return temperature boosting. At 25 kW, a buffer volume of 1,500 liters is a suitable minimum approach within the storage ranges specified for this output. The return temperature to the boiler must be at least 65 °C, while the boiler water temperature during operation is in the range of 80 to 90 °C. Return temperature boosting can be implemented, for example, with a Laddomat 22 or a correspondingly designed thermostatic valve or mixing solution.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e
