3 Tips on energy-efficient heating
Here are a few tips on how to heat economically, without
sacrificing comfort:
– Only heat if you need warmth. Use the preset
heating programs (standard programs) on the
controls or those which you have tailored to your
personal needs.
– Ventilate smartly during the cold season: Open the
window three to four times per day for approx. five
minutes. Having the window slightly open all the
time does not provide fresh air changes and
wastes valuable energy.
– Close the thermostatic valves while ventilating.
– Windows and doors are places where a lot of heat
is lost. So check that the doors and windows are
properly sealed.
– Never position large objects such as a sofa or a
desk immediately in front of the radiators, and
maintain a clearance of at least 1 foot (30cm).
Otherwise the heated air cannot circulate and heat
the room adequately.
– In those rooms which you occupy during the day,
a room temperature of 70°F (21°C) is
recommended. 63°F (17°C) may be sufficient at
night. To achieve this, use the standard heating
mode (day mode) and the setback mode (night
mode), (see Chapter 6 "Basic functions",
page 19).
– Never overheat rooms; overheated rooms are
unhealthy and waste money and energy. If you
reduce the daytime room temperature, for
example, from 70°F (21°C) to 68°F (20°C), you will
save around six percent on your heating bill.
– Heat in an energy-conscious manner during
shoulder seasons too, and make use of the warm
weather shutdown (WWSD) function (see
Chapter 7 "Extended functions", page 28).
– A comfortable room climate depends not only on
the room temperature but also on the relative
humidity. The drier a room, the cooler it feels. You
can optimize the relative humidity with house
plants.
– You can also save energy when heating DHW.
Only operate the DHW recirculation pump via a
timer. Research has shown that it is generally
sufficient to run the DHW recirculation pump for
three minutes in every half hour.
– Arrange with your local heating contractor to
service your heating system annually.
