Filling the water heater
WARNING: The water heater can crack if filling is
performed in the wrong order.
▶ Fill and pressurise the water heater before filling the
heating system.
Do not forget to vent after filling the outer shell and
commissioning the system.
Anode
For extra safety there is an electronic sacrificial anode installed in the
water heater. The task of the anode is to protect against corrosion to give

the water heater a longer service-life. In cases where there are thought
to be high amounts of chlorides in the water (>10 mg/litre), inspect the
anode every 1-2 years. The anode (aluminium) which is on the top of the
water heater has an original diameter of 20 mm. If it has been affected,
e.g. its diameter has been reduced to 5-8 mm or is 10 cm long, it should
be replaced and re-inspected after 2-3 years.
▶ Pressurise the water heater (outer-shell first).
▶ Shut off the main cold water supply.
▶ Open the venting cock.
▶ Unscrew the anode at the top of the water heater, check and replace
if necessary.
In confined spaces (low ceiling heights) a chain anode is available as an
alternative. Order anodes from your local installer specifying the tank
model.
