Yes, in winter, you should set your fan to Auto rather than On. This is the most energy-efficient choice, ensures only perfectly heated air comes out of your vents, and reduces the frequency with which you need to change your filters.
The best part of leaving your thermostat to Auto is you never have to think about it again. The fan turns on when the furnace or air conditioner starts running and goes off when your home reaches a set temperature. It's a simple, no-fuss, energy-efficient approach to your heating and cooling needs.
The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when you're at home. Energy.gov suggests that 68 degrees is a good room temperature while you're awake at home but recommends lowering it while you're asleep or away.
If you want to save energy and money, the answer is usually “auto.” Here's why: When your thermostat is in the “on” setting, the blower will run regardless of whether the temperature set point has been reached.
The main benefit of setting the thermostat to 'Auto' is that it will result in more energy efficient usage. This is because the fan will run only when it's required. Also, the air filter will need to be changed or cleaned less frequently when the thermostat setting is set to 'Auto'.
Average House Temperature in Winter
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.
AUTO means that the fan turns on automatically only when your system is heating or cooling air. Once the thermostat reaches the desired temperature, the entire system shuts off until the next cycle. ON means that the fan is constantly on and blowing air when your HVAC system is not heating or cooling air.
While it may be tempting to save a few bucks on your heating bill at times, a cold snap is not the time to set back the thermostat if you have pipes that are at risk of freezing. Leave the heat on if you plan to be away during cold weather. Set the thermostat to a temperature no lower than 55° F.
Use thermostatic radiator valves
If the room is warmer than the setting on the TRV, the valve will close a little. This reduces the volume of hot water flowing into the radiator. If the room temperature is lower than the valve setting, the valve opens, increasing the flow of hot water into the radiator.
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.
To save money, aim to have your temperature set around 68-72 degrees Fahrenheit when you're at home and awake. This is a comfortable temperature for most with the help of a light sweater. Overnight and when you're out, around 64 degrees Fahrenheit will keep your home at a good temperature.
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.
It's better to leave interior doors open when heating your home. Open doors allow warm air to circulate evenly, preventing hot and cold spots and reducing the strain on your HVAC system. Closed doors can block airflow, making your system work harder and increasing energy costs.
According to the U.S. Department of Energy, the ideal thermostat setting in the winter is about 68°F when you're awake and at home. This temperature keeps most households comfortable while keeping energy use in check.
If you'd like to calculate your ideal HVAC fan runtime, here's a simple formula: Measure the square footage of your home. Divide the square footage by 2. This number represents the number of minutes your HVAC fan should run per hour.
Set your heating to activate between 30 to 60 minutes before you wake up. Allow it to warm the room gradually, so you're not jolted awake by the thermal equivalent of a slap in the face. Turn it off or way down as you leave, so you're not wasting money heating an empty space.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
Main causes for high gas bills
How much does it cost to run gas central heating per hour? If you're connected to mains gas, you're looking at a cost of around 7pper kilowatt-hour. This means that if you have a 24 kW boiler, you can expect to pay around £1.68per hour to run it on mains gas. Information correct as of the October 2023 price cap.
When a cold snap hovers around or below 32 degrees Fahrenheit for a couple days in a row it's time to let at least one faucet drip. Pay close attention to water pipes that are in attics, garages, basements or crawl spaces because temperatures in these unheated interior spaces usually mimic outdoor temperatures.
While we know that water freezes at 32 degrees Fahrenheit, keep in mind that indoor pipes are somewhat protected from the extreme outdoor weather. Without a heat source, pipes may take as little as 3 hours to freeze at 20 degrees Fahrenheit or lower.
In the colder months, a winter thermostat setting of 68° F should be comfortable for you, your children, and your pets when you are at home and awake. You can then set it lower — say, 63-65° F — while you sleep to save even more.
The best part of leaving your thermostat on Auto is that you never have to think about it again. The fan turns on when the furnace or air conditioner starts running and turns off once your home reaches the set temperature. It's a simple, no-fuss, energy-efficient approach to your heating and cooling needs.
ECO Mode: The best option for keeping consumption low over the long term. AUTO Mode: Provides a balance between comfort and savings. SLEEP Mode: Ideal for reducing energy use during the night.
In this mode, the unit will run on HEAT or COOL depending on the room and set temperatures. Simply set the desired temperature and the inverter compressor will speed up and slow down to maintain temperature. Once the temperature is reached, the outdoor unit will slow down and eventually stop.
