This leaflet from BDH (The Federal Industrial Association of Germany House, Energy and Environmental Technology) concerns the annual inspection and maintenance of heating systems.
Maintaining the reliability, energy efficiency and low environmental impact of a heating system requires regular maintenance and control.
The EU Directive 2010/31/EU on the " Energy Performance of Buildings" requires periodical inspection, while the German Energy Saving Ordinance (Energieeinsparverordnung) requires a regular assessment of heating installations.
In this context, this leaflet describes the inspection and maintenance procedure for heat generators and solar thermal systems. Annex 1 gives the definition and a list of spare parts, ware parts and auxiliary material. Annex 2 references European directives and national regulations, together with technical rules and standards.
