Heating system inspection

Heating systems should be regularly maintained for the following
reasons:
• to achieve a high level of efficiency and to operate the system
economically (low fuel consumption),
• to achieve a high level of operational safety,
• to maintain the cleanest possible combustion
• to ensure reliable operation and a long service life.
Servicing work may only be carried out by a qualified service
technician. If parts are replaced, only Buderus-approved
components may be used. Maintenance must be carried out once a
year. The results of the inspection must be recorded in the
inspection and maintenance log.
Spare parts can be ordered from Buderus using the parts
list.
