ATMOS AC 25 S

Product detailed description

– 26 kW gasification boiler for brown coal briquettes, black coal and wood – COMBI with extraction fan and cooling loop

It is designed for burning briquettes on the principle of generator gasification using an extraction fan (S), which draws flue gases out of the boiler.
The boiler body is made as a welded construction from high-quality steel sheets 3 to 6 mm thick. It consists of two chambers positioned one above the other - the upper one serves as a fuel hopper, the lower one as a combustion chamber and ash pan. Between them is a new, patented, rotating grate, which enables perfect gasification of the fuel and easy removal of ash. At the rear of the boiler body is a vertical flue gas duct, fitted at the top with a lighting-up flap. The upper part of the flue gas duct is fitted with an extraction neck for connection to the chimney. Primary and secondary air is preheated to a high temperature to achieve high efficiency and quality combustion.

Frequently Asked Questions

• How to choose the correct output for a solid fuel boiler? Base your choice on the calculated heat loss of the heated building; however, for wood/coal boilers also consider that the boiler burns for several hours at essentially constant output during one filling - therefore it is common practice to add a storage tank to the boiler, which stores excess heat for later use instead of the boiler having to be inefficiently throttled down.
• What else do I need for the installation of this boiler? In addition to the boiler itself, the system usually requires: a storage (buffer) tank of appropriate volume, a circulation pump (often already with a built-in Laddomat or thermoregulatory valve against low-temperature corrosion of the boiler), a safety valve, an expansion vessel and a flue/chimney with sufficient draught corresponding to the boiler output - the exact draught values can be found in the technical parameters above.
• What fuel is suitable and what is not? Use only fuel recommended by the manufacturer for the given model (usually split wood of a defined length and moisture content, or brown coal briquettes or coal depending on the boiler type) - unsuitable or excessively moist fuel reduces efficiency, increases the formation of tar and deposits, and can cause damage to the boiler.
• What about chimney inspection and legislation? Before putting the boiler into operation, as well as regularly during its use (usually once a year for solid fuels), a chimney sweep authorized by law must inspect/clean the chimney - without the relevant inspection document, an insurance claim in the event of a fire may also be disputed.
• How much maintenance does the boiler require? This usually includes regular removal of ash and cleaning of heating surfaces/flue gas passages from soot (interval depending on intensity of use, usually in the order of weeks), and once a year a thorough inspection including seals and the chimney.
• Can I install the boiler myself? The actual placement and connection of the boiler to the heating system, chimney and safety elements should be carried out or at least professionally checked by a heating technician - this is a device with open fire, high temperatures and pressure elements, where a connection error can be a safety risk.
