For home heating, the optimal daytime temperature is 68∘ F when you are awake and home. Lower the thermostat by 7∘ F to 10∘ F overnight or when away for over four hours to save up to 10 % on your annual energy bill.
Yes, 73°F is a perfectly good temperature if you prefer a warm and cozy home. However, because it is on the higher end for winter heating, it will result in higher energy bills.
In the winter, 70°F is better for comfort, while 60°F is better for energy savings. However, 68°F is widely considered the ideal "sweet spot" by the Department of Energy.
The most energy-efficient heat setting for winter is 𝟔𝟖∘𝐅 while you are awake. To maximize savings, drop the thermostat by 77𝟕 to 𝟏𝟎∘𝐅 for eight hours while sleeping or away. This simple adjustment can reduce your heating and cooling bills by up to 10% annually.
68 to 72 degrees is a temperature range that is not too warm or cool, and is sufficient enough to warm up the home just enough so that everyone is comfortable regardless of the type of clothing they have on.
One of the leading reasons homes feel cold during winter months is heat loss through windows and doors. Older or poorly sealed windows and doors allow cold air to seep in and warm air to escape. This not only makes rooms feel colder but also forces your heating system to work harder, increasing your energy bills.
No, it is generally not cheaper to leave your heating on low all day. According to the U.S. Department of Energy, maintaining a constant temperature results in continuous heat loss, causing your system to consume more overall energy.
For most healthy adults, 68°F (20°C) is not considered too cold and is actually the standard indoor temperature recommended by the U.S. Department of Energy. It serves as a great sweet spot for balancing physical comfort with energy savings.
It is almost always cheaper to lower your thermostat when you are away or sleeping than to maintain a constant temperature, according to the Department of Energy.
The "30-minute heating rule" is a highly efficient, money-saving thermostat strategy that involves turning your heating system on 30 minutes before you need a space warmed up, and turning it off 30 minutes before you no longer need it.
65 Degrees is (Nearly) the Perfect Temp
For most people, 60 is a chilly sweater-friendly temperature, while going over 70 can get a little toasty. The most efficient setting for your thermostat is around 65 degrees in the winter when temperatures outside have dropped to 50 or below.
Insulate central heating and hot water pipes
Insulating central heating and hot water pipes might reduce the amount of lost heat, which helps you save energy and money on your heating bills. You don't need to insulate every pipe - ask a plumber or heating engineer if any of your pipes are worth insulating.
In general, industry experts say you can set your thermostat between 50 and 65 degrees when you're away in winter. But don't go lower than 50 degrees Fahrenheit, or you run the risk of pipes freezing in extreme cold.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
While 72 degrees is a popular choice among homeowners, it's actually lower than what's recommended for energy efficiency. The Department of Energy suggests setting your thermostat to 78 degrees during the summer months.
It is OK to set your thermostat to 74°F if you're happy with that temperature. However, many people find temperatures between 68°F–72°F more comfortable for everyday living. If efficiency is a concern, you might want to consider lowering the temperature by a few degrees to save energy.
Turning the heat completely off and on manually can actually raise your heating bill if done incorrectly. It is more efficient to maintain a lower, steady temperature and use a programmable thermostat to schedule adjustments when you are asleep or away.
Known for his practical tips, Lewis introduced the '4pm rule' which involves using curtains strategically to retain heat. He suggests opening curtains when the sun rises at around 8:30am to let in natural warmth, and closing them by 4pm to keep the heat inside.
Heating and cooling (HVAC) systems are the biggest energy consumers in a typical home, accounting for about 40–50% of your total electricity bill. Water heating, refrigerators, and lighting follow closely behind.
Regardless of how long you will be traveling and away from home, keep your thermostat set at 68 degrees Fahrenheit or above. This will help to keep the pipes on the inside of the home from freezing and the ones under the home at a slightly higher temperature as well.
An indoor temperature of 65 degrees (∘raised to the composed with power∘F) feels cold primarily because of low humidity, poor air circulation, and radiant heat loss. The air may also be warmer than the objects around you, and your body might be conditioned to warmer environments.
Here's a simple guide for September and October: Daytime: Set your thermostat between 68°F and 70°F for a cozy, energy-efficient home during the day. Nighttime: Lower the temperature to 60°F or 65°F while you sleep to save on heating costs without sacrificing comfort.
Typically, a furnace should cycle 3 to 8 times per hour, running for about 10 to 15 minutes each time. If it's cycling more frequently (short cycling) or running for 20+ minutes straight regularly, something's not right.
A 1500W heater (1.5 kW) at $0.17/kWh: 1.5 kW × $0.17 = $0.26 per hour (if running continuously). Note: Heaters typically do not run continuously to maintain a rooms temperature.
