Those who have central heating do not have to lose sleep over this dilemma. They do no more than beg the president of the community of neighbours to give the order to fire up as soon as possible, or complain when this is brought forward. Things will change in December 2016 when the new European regulations come into force and each community is obliged to install an individual meter. It is estimated that this measure will bring down the bill for those who take care not to waste heat as each household will pay for exactly what it consumes.
But for now, they are the masters and lords of the temperature of your home spending the winter using trial and error, studying the bills in detail. A brother-in-law said that if the temperature is kept at 19 degrees all day you pay less. Try the following for a month. To check if setting it at 37 degrees for the two hours we are out saves all the day’s heat and costs less… what stress!
The reality is that, contrary to popular belief, leaving it at ambient temperature does not save anything. According to IDEA, the Spanish Institute for Energy Diversification and Saving, you should switch your heating on when your home is really occupied and turn it off or lower the thermostat to between 15-17ºC in the evening.
