Heating insert SD 6 F

Our smallest and narrowest.
The SD 6 F heating insert is characterized by its low installation depth of only 45 cm. Ventilation for convective heat is integrated in the front panel. Heating with wood or brown coal? Since the end of 2016, the SD 6 F has now also been approved for mixed firing. So you can change the fuel type quickly and easily.

Front panel: 420 x 820 mm
body: 330 x 700 x 450 mm
Type: Door hinge on the right, self-closing, not changeable
Wood performance: 6 kW
Performance of brown coal briquettes: 4 kW

Multiple glazing

The multiple glazing ensures approx. 30% less heat emission via the glass pane, higher combustion chamber temperatures and clean panes over a longer period of time.

inner lining

Our heating inserts are equipped with solid fireclay bricks which are placed in the device dry, without walling in.

stove body

The furnace body consists of high-temperature resistant furnace casting. This material has proven itself over decades.
