In general, it's recommended to set your thermostat to 55 degrees Fahrenheit or higher. This may seem high compared to the freezing point of 32 degrees Fahrenheit, but it'll help keep the interior of the floor and wall cavities – where your plumbing is often located – safely above freezing temperatures.
Whether you plan to leave for a vacation or for the season, most heating and cooling professionals recommend setting the thermostat to 55 degrees Fahrenheit. This temperature will reduce your heating costs and minimize the risk for hazards such as frozen or burst pipes and flooding.
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.
A couple of hours twice a day of heating, around 14-15 degrees a day should keep the internal temperature in the house above freezing and stave off any freezing in the pipes. Keep the heating on, at a very low level, (around 12 degrees Celsius) all the time.
But while a lower temperature may reduce your heating bill, it could mean disaster if a cold temperatures hit, and your pipes freeze and burst. This doesn't mean you have to keep your house as warm as normal — any temperature 55 degrees or higher is appropriate to keep your pipes safe.
Insulating your pipes and water tanks is one of the best ways to prevent them from freezing. You can buy inexpensive pipe lagging and tank jackets from most DIY stores and fit them yourself for free. Just make sure you check the pipe and tank measurements first.
Don't turn your thermostat down below 65 degrees during extreme cold. Further drops in temperature could be enough to cause a problem, especially inside walls where pipes are located. Your heating bill may go up a little, but that's better than an expensive repair job if a pipe freezes and bursts.
Keeping your home warm in the winter is essential for one's comfort and also to keep pipes from freezing. However, you should be mindful of energy consumption as well. According to the Department of Energy, the optimal temperature setting for homes during freezing weather is 68 °F.
Recommended Temperature When the Home is Vacant
For short periods of time away, like going to work, we'd recommend a temperature of around 55 – 60 degrees (F). While away on long periods of time, such as vacation, we don't recommend setting the temperature any lower than 50 degrees (F).
The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees Fahrenheit for healthy people. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems. Watch out for signs of hypothermia.
In the winter, set your thermostat to 68 degrees or the lowest comfortable temperature. In warmer months, set it to 78 degrees or higher. It's a no-cost option to reduce energy expenses. At night or when you're going to be away from home for an extended period, adjust the thermostat a few more degrees.
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.
If you're in the house, it needs to be around 18-20 degrees. Your breath + cold walls = condensation and mould. If you're not in the house, it's something like 14-15 degrees to protect the piping. Common mistake is people lower the tempt to reduce their heating bills then get tons of mould.
Set your thermostat (don't turn it off) at the lowest temperature that will keep your pipes from freeze damage (at least 50 to 55 degrees should do it). You want it warm enough to keep your pipes or anything else from freezing.
During winter, the lower the interior temperature, the slower the heat loss. So the longer your house remains at the lower temperature, the more energy you save, because your house has lost less energy than it would have at the higher temperature.
In general, it's recommended to set your thermostat to 55 degrees Fahrenheit or higher. This may seem high compared to the freezing point of 32 degrees Fahrenheit, but it'll help keep the interior of the floor and wall cavities – where your plumbing is often located – safely above freezing temperatures.
The best winter thermostat setting is 62 to 68 degrees. On winter days, program your home's thermostat to 68 degrees for a comfortable indoor temperature while you're home and awake. When sleeping, program your thermostat to 62 degrees. Consider rolling this temperature back to 55 degrees when no one is home.
During heat waves, experts, including utility companies, recommend keeping your thermostat no more than 20 degrees cooler than the outdoor temperature. For instance, if it's 100 degrees outside, aim to set your thermostat to at least 80 degrees.
In fact, you're likely only to see savings of a few cents a day depending on the make and model of your unit. Unless you'll be vacating your home for a month or longer, turning off your water heater is unnecessary.
When temperatures approach zero, wind can penetrate through a small opening and can freeze nearby pipes, even thought the room temperature is 70 degrees! Insulate pipes in unheated garages and crawl spaces.
What's The Lowest Temperature I Can Set My Thermostat in Winter? Do you just love the cold so much you'd rather not run any heat in winter? The winter thermostat setting should at minimum be between 50-55 degrees to keep your appliances and pipes from freezing.
So, exactly how cold does it need to be before you do this? Southern Living says professionals list the threshold temperature for pipes to freeze at 20 degrees Fahrenheit, meaning this or anything below can create a potential for water to turn to ice in your pipes.
