Stable construction: The body is primarily made of robust steel and cast iron. Additionally, the combustion chamber is heat-resistant and lined with firebrick. The wide filling door opening allows for the convenient insertion of larger logs. 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 burned off, leading to even higher energy utilization. This process also results in lower pollutant emissions into the environment. The WO 109-8F additionally features a viewing window.
