All our stoves are made of high quality marine aluminum. The thermal conductivity of aluminum is about 15 times better than the stoves made of stainless steel and therefore our stoves are up to 30% more effective.
The material is 3 mm thick, which is two times more than in case of regular furnaces made of stainless steel. And of course, aluminum furnace is 30% lighter. Aluminum furnaces have longer useful life than furnaces made of stainless steel. The aluminium heaters retain their shape for a long time. Heaters made from thin stainless steel may become crooked.
High-quality MIG welding ensures the perfect end result. We check and test impermeability of all welded seams.
