The GRA-G is the largest and most powerful EWI-Therm slow-combustion stove.. Equipped with a double jacket, it is the only stove which has an additional fan on the back side. Room heating is based on the circulating air principle.

Controlled by a thermostat, the fan takes in the cold room air, leads it through the furnace jacket and releases it in heated condition at the floor. According to this method, the rooms are heated quickly, evenly and without dust turbulences.
