Does using a thermostat save energy?


If I set my thermostat to consistently stay on a certain temperature, will that use less energy than needing to cool/heat?

    Hi Luci, here is the information on saving energy. Hope this is helpful. You can save energy and keep your costs in check by keeping your thermostat at 68 degrees Fahrenheit during the daytime. reports that turning your thermostat lower by 10 to 15 degrees for 8 hours per day will help you see an energy usage reduction of 5 to 15 percent per year on your bill.

    Luci, I work in the HVAC industry and the answer to your question is.... It depends. Let me explain. If using air conditioning, the appliance has to first remove humidity from the air (called latent heat) before it can drop the room temperature (sensible heat.) When you turn off an air conditioner, this humidity immediately starts to rise so if using air conditioning, it is best to adjust the temperature up when unoccupied and down when occupied by just a few degrees but to keep the air conditioning turned on. This is because it takes a lot more energy to remove the humidity described above than to just lower the temperature. This is where a programmable Thermostat is really helpful. A good example is to set it to 78 when home and 82 while at work.
    For heating, it's a little different. In most cases the humidity is not an issue in winter months. For winter conditions, it's usually best to keep your Thermostat temperature set lower when you are at work or sleeping and tucked under the covers and slightly warmer when getting ready for work or relaxing around the house. It's best to not lower the temperature below 55 so that plumbing pipes don't freeze. Most thermostats have a bottom temperature of 55 or 60. Turning the heater all the way off could leave your home at risk for freezing pipes and other costly damage, so it's not all about energy conservation at that point.
    A programmable Thermostat is one of the best ways to save money if you program it to match your life.

    Some people put timers on their thermostat so it kicks on before you would be home from work, turns it down at bed time, and kicks it back up before you rise in the a.m. We leave ours at a cool temperature and put on warm every day clothes and heavy socks in the house. We supplement with throw blankets as needed. Temperature is what you get used to in the home. I hope this helps.

    I find I save money in my old 40s house leaving the heat on a low temp all the time versus turning down when I leave and heating up when I return.
