Wood-burning stove GEFEST GFS ZK 40 President 1140/60 with soapstone exterior finish. For saunas up to 40 m3. It heats up to 700 degrees in 60 minutes and retains heat for a long time. Holds up to 40 kg of stones.
To increase the heating surface area of the stones, cast iron spikes pointing upwards were installed on the outside of the furnace. Bath stones, cast iron cores or cast iron cones are placed between the needles. Cast iron needles increase water evaporation. By opening the top lid of the oven and pouring water on the hot stones, you will get plenty and soft steam.
The stones are purchased separately.
