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.
The water temperature should be around 45 degrees (1). Keep the thermostat at a minimum of 68 degrees Fahrenheit: During the winter, it is important to maintain a consistent temperature inside your home. Keeping the thermostat at 68 degrees Fahrenheit or above helps to prevent the pipes from freezing (3).
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.
🌡️ Keep your pipes warm
Ideally, the lowest you want to keep your thermostat set at is 50 degrees, but heating is expensive. According to Thompson, the absolute lowest you can go is 40 degrees, because your pipes will start freezing at 39 degrees.
Pipes can freeze when the temperature stays at or below 0°C for an extended period of time, especially if they are exposed to the cold.
Ways to avoid frozen pipes
Keep each room in your home warm by setting your thermostat to a minimum of 16 degrees centigrade. If you're worried about your heating bills, turn the radiators down in the rooms you don't use. If you have a loft, leave the hatch open to allow warm air to enter the roof space.
Yes, pipes can freeze overnight if temperatures plummet drastically. Uninsulated pipes in unheated areas like attics or exterior walls are most vulnerable.
Your pipes are at risk of freezing any time temperatures drop below 32°F. However, it's much more common for pipes to freeze when temperatures dip below 20°F. The longer the weather remains below freezing, the more likely it is your pipes can freeze if not properly protected and winterized.
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.
Frozen pipes generally occur below 20° F. But freezing can happen above that threshold as well, especially if you have uninsulated pipes running through an uninsulated space. Keep garage doors closed, especially if there are water supply lines in the garage.
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home. If there are infants or elderly individuals, they recommend keeping the temperature at 70 degrees at a minimum.
Prevent Frozen Pipes
Moving water keeps pipes from freezing. Find shut off valves for emergencies. Insulate pipes in unheated areas. Open cupboards and vanities to warm pipes.
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.
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.
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.
The maximum temperature for long term water heat pipes is 270 °C (518 °F), with heat pipes operating up to 300 °C (572 °F) for short term tests. The main reason for the effectiveness of heat pipes is the vaporization and condensation of the working fluid.
If you live in a climate with freezing temperatures, you'll want to cover your outdoor faucets in the winter rather than dripping them. Even with a vigorous drip, frigid temperatures can travel through your faucet and freeze the connecting pipes. Before using a cover, you'll need to properly winterize your faucet.
Here's a list of ways to prevent freezing pipes in your home: Keep the thermostat at a minimum of 68 degrees Fahrenheit. Make sure pipes are properly insulated. Keep water slowly flowing on outer wall faucets.
Although common, frozen pipes do not always burst. However, the ice can increase this risk when it thaws and is usually worsened as it raises pressure further which makes pipe bursting common near winter's end or springtime. Furthermore, the more water flowing through the pipe, the greater chance of rupture.
At what temperature do pipes freeze? Technically pipes can freeze in 32-degree weather, but most will not freeze until under 20 degrees. The longer the temperature remains under 20, the greater the chance of freezing. Pipes can fully freeze within six hours if the temperatures are cold enough.
How Long Does It Have To Be Below Freezing For RV Pipes To Freeze? It will only take about 24 hours of below-freezing temperatures (lower than 32 degrees Fahrenheit) for the pipes to freeze in your RV.
Overall, it's best that you take heed and drip your faucets when temperatures dip below freezing. A simple trickle of hot and/or cold water—both from faucets inside and outside the home—can prevent you from having to deal with a much larger issue (and bill!) in the long run.
