HOW TO SAVE ENERGY WITHOUT FOREGOING ON COMFORT
– A temperature of around 21°C is advised in the rooms
that are used. Every degree above this will increase hea-
ting costs by 6–7%.
– Aerate the rooms only for a brief period, opening the win-
dows completely.
– In the rooms that are not used place the regulating valve
in the antifreeze position.
– Leave the space in front of the radiators free from
obstructions (remove furniture, curtains...).
– Close windows and blinds to reduce
dispersion of heat.
