If there is reason for concern for contamination from bacteria such as
legionella, consider setting the DHW thermostat to at least “e”
(131 °F (55 °C)).
This setting ensures an economical and comfortable DHW
generation. Consult your local water department or municipality for
further information.
DHW thermostat Typical DHW temperatures
min approx. 59 °F (15 °C)
e approx. 131 °F (55 °C)

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).
