There is nothing like a good debate between friends to get to the bottom of some of those questions that everybody wonders about. I received one of those questions by e-mail the other day and thought I would give it to all of you to come up with the best answer.
A co-worker and I are having an ongoing debate: Is it more energy efficient to turn down the house thermostat during the day (after leaving for work in the morning at about 7:00 am since no one is home) to 50 degrees, then have it turn on automatically at 3:00 pm to 67 degrees to warm the house up for a 6:00 pm return or to keep it at a constant 67 degrees the entire day?
My co-worker contends that too much energy is consumed to return the temperature to 67 to make it economical. Do you have information on this?
I asked a couple of friends what their opinion was and it seems that there is a fairly even split between those who believe that leaving the temperature at a constant while you are gone and those who believe you should turn the temperature down is better. I am sure that there are plenty of other people who would like to know which is more environmentally friendly and I’m sure that the readers here will shed light this issue.
