Servicing the boiler

Permanent operational readiness and safety, reliability and
a long working life require inspections and maintenance
work to be carried out annually on the boiler by a compe-
tent person.
Regular servicing ensures maximum efficiency and a more
economical operation of your boiler.
We recommend making a maintenance agreement.
