Hwam Classic 4 + Ofn
All HWAM wood-burning stoves are convection stoves.
This means that the wood-burning stove quickly emits heat after lighting.
The heat is transferred by a natural air current, and not by heat radiation.
This results in a pleasant indoor climate and a uniform temperature throughout the entire room.
Another advantage is that the outer cap of the wood-burning stove does not become especially hot.
This is to say that furniture can be placed quite close to the wood-burning stove.
3 WAY „AIRWASH“
Dancing flames are both fascinating and relaxing. Furthermore, flames are beautiful in all phases from the initial lighting to the burning of coals.
For this reason, it is important that the glass pane on a HWAM wood-burning stove does not become sooty during combustion.
HWAM has developed a technique that ensures that the glass pane always receives heated air from three sides in order to prevent it from becoming sooty.

HWAM Classic 4
The mechanical HWAM Autopilot with its heat sensitive spring ensures the correct air supply for the different combustion phases enabling an optimal combustion.
HWAM unique Autopilot is a strikingly, yet ingeniously brilliant function which offers numerous benefits - both for you and for the enviroment.
• Simple, convenient operation
• Clean burning
• More enegy, better economy
• Easy on the enviroment
The automatic dampers ensure that the combustion air is led to the right places in the combustion chamber, in the right quantities and at the right time to ensure optimum combustion.
Simply light, sit back and enjoy...
The bimetallic spring in the HWAM automatic controls the positions of the dampers. As the temperature in the combustion chamber rises, the spring expands and moves the dampers, shutting off the supply of primary air and opening up the supply of secondary air. It is solely the temperature in the combustion chamber that determines how the dampers move. The entire process is ongoing so that the supply of air for each stage of combustion is adjusted precisely to ensure the most eco-friendly, fuelconserving combustion.
The first schematic diagram simply shows the vast of heat that is lost when you leave a stove unattended without HWAM Autopilot.
The second diagram shows the immense savings a HWAM Auopilot makes. You simply light the fire - the HWAM Autopilot will completely control the fire for you automatically regulating the stove so that it continually achieves optimum combustion and prolongs the refill period.
