The standard version operates with a robust electromechanical control and is manually ignited. It is suitable for heating systems where a classic, clear boiler control without automatic wood ignition is desired.\u003c\/p\u003e \u003cp\u003eThe DC22GSE can be used particularly in single-family and two-family homes as well as in renovations, modernizations, and the replacement of existing wood heating systems. For product selection, the 23 kW output is assigned as a guideline for the building class of 200–300 m². The final sizing depends on the actual heating load of the building.\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 wood gasification principle with reverse combustion. The ceramic-lined combustion chamber supports the combustion of the resulting wood gas at high temperatures. Primary and secondary air can be adjusted separately, while an induced draft fan supports the combustion and flue gas process. The tubular heat exchanger in the rear boiler area serves to transfer heat to the heating water.\u003c\/p\u003e \u003cp\u003eThe standard control operates electromechanically. The boiler output is influenced via the air flap and the draft regulator Honeywell FR124. Boiler thermostat and flue gas thermostat control the induced draft fan and support automatic shutdown after the fuel has burned out. Ignition itself is manual.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe DC22GSE combines comparatively simple control technology with the functions typical of the GSE series for a wood gasification boiler. The 86-liter fuel shaft and the filling opening of 450 × 260 mm enable practical loading with split logs up to 330 mm in length. After the burn-off, the flue gas thermostat can switch off the fan and the boiler circulation pump.\u003c\/p\u003e \u003cp\u003eWhen reloading and during maintenance work, the induced draft fan supports the flue gas routing. The thermal safety drain protects the boiler against overheating in conjunction with the required safety valve.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe DC22GSE is designed for operation with a buffer tank and effective return temperature boosting. The current ATMOS design requires at least 55 liters of storage volume per kilowatt of boiler output. For 23 kW, this calculates to a minimum of 1,265 liters. For the 20–25 kW output class, the system design specifies a buffer volume of approximately 1,500–2,000 liters. The specific tank size must be matched to the heating load, hydraulics, and desired operating behavior.\u003c\/p\u003e \u003cp\u003eThe return temperature to the boiler must be at least 65 °C. In normal operation, a boiler temperature of approximately 80–90 °C is intended. The required chimney draft is 18 Pa. Return temperature boosting, buffer tank, safety heat exchanger, and flue system must be properly designed as a complete system.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"product-th\"\u003e \u003ch2\u003eTechnical data at a glance\u003c\/h2\u003e \u003ctable class=\"product-th__table\"\u003e \u003ctbody\u003e\u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eNominal heat output\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e23 kW\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eHeat input\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e25.3 kW\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eEfficiency\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e90.7 %\u003c\/td\u003e\n\u003c\/tr\u003e \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 \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eEnergy efficiency index EEI\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e119\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eSeasonal space heating energy efficiency\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e81 %\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eFuel\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eDry log wood, 12–20 % moisture content\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eMaximum log length\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e330 mm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eFuel shaft\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e86 l\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eFilling opening\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e450 × 260 mm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eBuffer storage tank\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eCalculated minimum 1,265 l;
