Heating system servicing
9.1
Why is regular servicing important?
Heating systems should be regularly maintained for the
following reasons:
– to maintain 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
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 services must
be recorded in the service and maintenance report.
Offer your customer an annual contract covering
inspection and demand-dependent service. The work that
needs to be included in a maintenance contract is
detailed in the inspection and service reports
(

Chapter 9.5, page 55).
