Having the heating on too high causes an unnecessary additional expense. Keeping it at 21 degrees is sufficient to heat a home. Remember that heating does not have the aim of reproducing the summer temperatures to walk around the house in a vest. We should dress in clothes according to the time of year and, thus, prevent the bill from shooting up. With a thermostat you will find it easier to maintain an optimum temperature throughout the year and you will save between 8 and 13% on your consumption. Moreover, remember that you can control the operation of your heating from any point, via the Internet.
