4 Energy-saving tips
You can help to save energy by following the tips and
advice below:
Appropriate hot water temperature
The water should only be heated up to the extent that is
necessary for use. Any further heating will result in
unnecessary energy consumption. For you, this means
that you should:
>
Set your VED to stage I in normal operating mode.
>
Briefly set the output selector to stage II in special
cases where you need more hot water than stage I is
able to provide. After using the hot water, remember
to set the output selector back to stage I.

caused by limescale formation. In areas of
hard water (more than 14 °dH = 2.5
CaCO
3
mmol/l) or very hard water (more than
20 °dH = 3.6 CaCO
3
mmol/l), a significantly
more frequent maintenance interval may be
required.

Have your VED inspected at least every
3 years by a competent person.

If you live in an area with very hard water,
Vaillant recommends that you have the
maintenance service carried out once a
year by a competent person.
