If there is reason for concern for contamination
from bacteria such as legionella, consider setting
the DHW thermostat
(131 °F (55 °C)).
This setting ensures an economical and
comfortable DHW generation. Consult your local
water department or municipality for further
information.

Always set the DHW temperature as low as
possible.
A lower setting on the thermostat means a higher
rate of energy savings.
Furthermore, higher DHW temperatures result in
increased limescale deposits and thereby may
impair the function of the appliance (e.g. longer
times for heating up or lower output).
