The suitable replacement parts for the Buderus Logalux SM300/1 tank are listed under the replacement parts section for the SM300/1 - SM400/1 models. The document primarily provides details for the SM400/1 model, but since the Logalux SM300/1 and SM400/1 are grouped together, similar replacement parts may be applicable. Specific components such as insulation packages, tank covers, and other accessories are available. However, for exact compatibility, refer to the specific replacement parts list for the SM300/1 model.
