Stable construction: The body is primarily made of robust steel and cast iron. Additionally, the combustion chamber is heat-resistant and lined with fireproof material. The wide filling door opening allows for larger logs to be easily inserted. Clean combustion: WAMSLER workshop stoves are tested for the fuels wood and lignite. Depending on the type of fuel and operating conditions, secondary air can be dosed in. Unburned components are safely re-burned, leading to even higher energy utilization. This process also results in lower pollutant emissions into the environment. The workshop stove WO 109-6F also features a viewing window and top connection.
