Energy Saving Tips; Tips For More Comfort - Viessmann VITODENS 100-W Operating Instructions Manual

Energy saving tips

Central heating
■ Room temperature
Never overheat your rooms. Every
degree of room temperature reduction
saves up to 6 % on your heating bills.
Set your room temperature no higher
than 20 °C.
■ Operating modes:
If you do not require central heating,
select one of the following operating
modes:
– If you do not wish to heat rooms in
summer but require domestic hot
water, set rotary selector "tw" (see
page 13) and turn rotary selector
"tr" to "0".
– If you require neither central heating
nor DHW for a prolonged period, set
rotary selectors "tr" and "tw" to
"0".
■ Ventilation:
To ventilate, open the windows fully for
a brief time and meanwhile close the
thermostatic valves (if there is no
domestic ventilation system installed).

Tips for more comfort

DHW heating
■ Comfort function:
If the comfort function is switched on,
the instantaneous water heater is kept
up to temperature (standby). Hot water
is therefore quickly available. Start
comfort function (see page 14).
Introductory information
■ Roller shutters:
Close roller shutters (where installed)
at dusk.
■ Thermostatic valves:
Ensure that thermostatic valves are
properly set.
■ Radiators:
Never cover radiators or thermostatic
valves.
DHW heating
■ DHW temperature:
Never set the DHW cylinder tempera-
ture excessively high (see page 13).
■ DHW consumption:
Consider showering instead of running
a bath. A shower generally uses less
energy than a full bath.
