Room venting
Do not keep windows cracked for ventilation purposes as it continuously cools down
the room without significantly improving the air quality in the room. It is better to vent
fully for a short time (with completely open windows).
Turn off the thermostats (if installed) in the room when venting.
Domestic hot water (DHW)
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 heating-up times or
lower output).
Recirculation pump
If there is a DHW recirculation pump installed, use a timer program to control its
operation according to the specific requirements (e.g. morning, afternoon, evening).
