8 Heating system servicing
8.1 Why is regular maintenance important?
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 reliability,
– to maintain the cleanest possible combustion,
– to ensure reliable operation and long service life.
Servicing work may only be carried out by a qualified serv-
ice technician. If parts are replaced, only Buderus
approved components may be used. A service must be
carried out once a year. The results of the services must
be recorded in the servicing and maintenance log.
