5.3 Tips on energy-efficient heating
– You can save 6 % on your heating bills by reducing the daytime
temperature by 1 °C.
– Only run the heating if you need warmth. Use the switching
program for automatic night setback.
– Ventilate rooms correctly: open the window wide for a few
minutes rather than leaving it constantly open with a small gap.
– Close the thermostatic radiator valves when the room is being
ventilated.
– Ensure that doors and windows are correctly sealed.
– Never stand large objects, such as a sofa, immediately in front
of radiators (maintain a clearance of at least 50 cm). Otherwise
the heated air cannot circulate and heat the room adequately.
– You can also save energy when heating DHW: compare the
times at which rooms need to be heated with those at which
you need hot water. If necessary, use a separate switching
program for heating DHW.
– Arrange with your local heating contractor to have your heating
system serviced annually.
