Heating system inspection and maintenance
The inspection and maintenance of a heating system is specified by the Energy Saving Order
and the DIN 4755, DIN 1988-8 and EN 806 standards.
Regular maintenance ensures trouble-free, energy-efficient and environmentally responsible heating. For this, we
strongly advise you to arrange an inspection and maintenance contract with your local heating contractor.
DHW cylinder (if installed)
The DIN 1988-8 and EN 806 specify that maintenance
and cleaning should be carried out no later than two
years after commissioning and thereafter as required.
Only a qualified heating contractor should clean the
inside of a DHW cylinder and the DHW connections.
Refill any water treatment equipment (e.g. a lock or
injection system) in good time, if such equipment is
installed in the cold water supply of the DHW cylinder.
Observe the manufacturer's instructions.
Safety valve (DHW cylinder)
The safety valve function should be checked every six
months by venting, either by the system user or the
local heating contractor (see the valve manufacturer's
instructions). The valve seat may become contamina-
ted.
Additionally for a Vitocell 100:
We recommend that the correct function of the sacrifi-
cial anode is checked annually by your heating con-
tractor.
The anode function can be checked without interrupt-
ing the system operation. The heating contractor will
check the earth current with an anode tester.
