Hot-Air stove / Hot-Air heating system 

To get a closer look please move your "Mouse" over the hot air stove - picture on the left.

Shell
Due to the large volume and the double-type locking, which is just as simple as efficient, the shell warrants a secure, time-saving and effortless charging.

Induced draught blower
The Induced draught blower guaranties uniform combustion, independent of the location and draught intensity of the existing chimney; in addition, it can be manually regulated by a reducing damper.

Hot air blower
The double-side intake, powerful radial blower with external motor and V-belt drive guaranties both a high hot-air capacity and a low-noise operation

Fill and fire room / Combustion Room
The two-part combustion room with a thick fireproof special fireclay lining and cast-iron fire and soot door is designed for an operating temperature of up to 1,200°C.

Heat exchanger with de-dusting
A large-sized heating element made of steel 2 mm thick is surrounded by cast plates, 2 to 15 mm thick, according to DIN 1691, and permits the rapid transmission of combustion energy into hot air. A highly efficient radial blower conveys the heated air through ducts even into distant rooms. The integrated flue gas de-dusting system safeguards the observance of emission limits stipulated by the law.
