Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you're asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
According to ENERGY STAR, setting your thermostat to 68 degrees Fahrenheit (20 degrees Celsius) when you're home is the ideal balance of comfort and energy efficiency.
The reason being: it takes more energy to heat a cold house or to cool down a hot house than it takes to maintain a steady temperature.
Regardless of the type of heating you have in your home, turning the thermostat down to the lowest comfortable temperature is sure to save money over time.
The Department of Energy estimates savings of about 1 percent for each degree of thermostat adjustment per 8 hours, and recommends turning thermostats back 7 to 10 degrees from their normal settings for 8 hours per day to achieve annual savings of up to 10%.
When the average temperature outside rises above 65 degrees Fahrenheit, your system works harder to cool your house. That's why hot weather can affect your electric bill, even if you leave your thermostat on a constant setting.
In fact, leaving your heat on all day can actually cost you much more than turning it off every now and then. Heat tends to diffuse, so the high heat in your home will diffuse to areas of low heat outside the home during the winter. So even when you have your furnace on, your home is always losing a little bit of heat.

Here's the secret: Set the temperature of your home at least eight degrees lower for the eight hours or so that you sleep at night. Every degree you lower the thermostat can net you an estimated 1% off your heating bill. So, eight degrees for eight hours a day can save you up to $180 every year.
A viewer asked us to verify whether turning your heat on and off is more cost effective than leaving it running steady. Our researchers asked AC and Heating experts. They agree you should not turn your system off completely—then it'll have to work extra hard to reheat the house and it'll end up costing you.
What temperature should you keep your house at? Or better yet, “What is the most energy saving temperature to set my thermostat at?” According to ENERGYSTAR.gov, the ideal home temperature should be between 70 to 78 degrees Fahrenheit.
The Department of Energy recommends a winter heat setting of 68 °F (20 °C), which matches up very well with the temperatures most of us are comfortable with.
14-15° - If your home is this cold, you may be diminishing your resistance to respiratory diseases. 18° is the recommended night time bedroom temperature. 19-21° is the recommended daytime temperature range for occupied rooms.
Your AC will actually run longer overall if it is left on all day instead of being shut off. If you turn it off for part of the day, it runs less and results in more energy savings for you. In almost all cases, it will save you money to shut off your AC while you are away from home.
Heating one room, particularly if you have electric radiators can offer you a great reduction on your energy bills. Kitchens are potentially rooms that do not need heating, after all you are moving around when your are in there, getting food ready or making a drink.
However, the primary culprit of high winter energy bills is your heating system. Heating a home tends to cost more than twice as much as cooling a home.
To save money on your electric bill and to ensure maximum energy efficiency, it is recommended to alter your thermostat a couple of degrees depending on the time of year and if you're home or not. The recommended heating and cooling temperature for ideal year round comfort is between 70 and 78 Fahrenheit.
Temperature affects how electricity flows through an electrical circuit by changing the speed at which the electrons travel. This is due to an increase in resistance of the circuit that results from an increase in temperature. Likewise, resistance is decreased with decreasing temperatures.
The most comfortable room temperature will vary based on your personal preferences, the season, and which areas of the home you are living in. Most people can agree that a healthy range will go from 20 – 24 degrees Celsius (68 – 76 degrees Fahrenheit).
The average room temperature is typically around 20°C, or 68 degrees Fahrenheit. This is a good ambient temperature to aim for, but it is important to bear in mind that different rooms will need to be heated to specific temperatures.
The ideal healthy home temperature should be no higher than 20 degrees Celsius or 68 degrees Fahrenheit. When you're at home during the day, you'll be quite comfortable at this temperature.
