¿Cómo debo gestionar mi sistema de calefacción para que sea eficiente sin reducir el confort?
How should I manage my heating system so that it is efficient without reducing the level of comfort?
The IDAE's advice is to set your central heating so that it comes on when you are actually at home and turn it off at night when you go to bed, as while you are asleep a temperature of 15-17ºC is sufficient for comfort. You could leave it on at night with the thermostat set to 15-17ºC if you house is poorly insulated and loses a lot of heat at night. As a rule, turning the heating off at night and turning it on again for a few minutes when you get up is much more efficient than leaving it on all night.
