Every article I read about “Energy Programmable” thermostats say only positive things about them. They will cut your energy costs by ?% and take all the guesswork out of when you should down the thermo up or down. Most articles tell a homeowner to set the thermo back a few degrees at night and at times when the occupants are not at home.
That sounds great but! How much energy is used when the thermo clicks the furnace on . Now it has to work a little longer to bring the house back up to the occupant’s comfort level and maintain it.
I never see the articles address this aspect of setback thermos. I lean towards leaving the thermo at one setting and let the furnace maintain that setting all the time. Seems to me it would be steady as opposed to up and down, up and down.
What does everyone think about this issue?
