Checking the protective anode
Checking the protective anode only applies to stainless steel hot water
cylinders. At the top of the hot water cylinder, under the insulation, there is
a protective anode. The task of the anode is to prevent corrosion so the hot
water cylinder does not corrode away. The hot water cylinder must be fi lled
with water in order for the protective anode to work.
There are two types of protective anodes: a sacrifi cial anode and an
electronic anode.
Sacrifi cial anode
The sacrifi cial anode can corrode depending on the water quality. If the
diameter of the anode has been reduced to a few millimetres it must be
replaced. This is how you check the sacrifi cial anode:
1. Shut off the main cold water supply.
2. Open a tap and let the water run out to reduce the pressure in the hot
water cylinder.
3. Unscrew the anode from the heat pump and check its diameter.
Electronic anode
If the protective anode is electronic there is a control box showing the
status of the anode. The diode lamps are either green or red. If green, the
protective anode is operating and working normally. Red can indicate a
fault. When large amounts of hot water are used (e.g. with a bath) the lamp
may show red for a short period without there being a fault. However, if the
red light is on for more than ten hours this indicates the anode is faulty and
you should contact your dealer. If the fault occurs at the weekend you can
wait to the next working day before contacting your dealer.
If the diameter of the anode has been
reduced to a few millimetres it must
be replaced as soon as possible.
