8 Heating system servicing
8.1

Why is regular servicing 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 trained and
certified service 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 serv-
ices must be recorded in the servicing and maintenance
log.
Spare parts can be purchased from your
Buderus distributor using the parts list.
