Will Space Heaters Keep Pipes From Freezing?

Frozen pipes are an expected winter catastrophe. The extreme winter’s temperatures are not only punishing you but can freeze your pipes, risking bursts and other related problems like dangerous flooding in your home. Most frozen pipes occur in unfinished basements or behind poorly insulated exterior walls connected from wall to wall. 

When water freezes in the pipes, the ice expands and can crack the copper pipes. The water will seep through the cracks in the pipes when the pipes warm and the ice thaws. These damages are costly to homeowners. Being educated and prepared is the best way to prevent pipes from freezing.

In this post, we’ll address some concerns, such as if space heaters can keep pipes from freezing, and suggest other methods that can be used to achieve the same results.

Prevention is more cost-effective than ripping apart walls to insulate pipes even if you have to keep the space heaters constantly running for several days. The cheapest and easy fix to prevent pipes from freeing is space heaters.

Installing a space heater in your basement can keep any poorly insulated pipes from bursting as the heat will act as an insulation barrier. At this time of the year, plumbers have a long list of customers with similar problems. Most insurance companies will not pay for repairs without first sending an adjuster to inspect the damage.

Due to these factors, it can take some time to get the pipes fixed, leaving a portion of your home unusable. Hence you can be proactive and take preventive measures to save you headaches and a lot of money.

Why do Pipes Freeze in Winter?

When water freezes inside the pipes, the molecules expand, and density decreases, causing the ice to expand, pushing the ice towards the faucet. The expansion causes a significant amount of stress between the ice blockage and the faucet.

In the end, the pipes can handle the pipe buildup and bursts. Usually, the burst occurs in a location in the pipe where there is little or no ice. The more exposed the pipes are to freezing temperatures, the greater the risk of rupturing during winter. The pipes at greater risk are not insulated, and the indoor pipes are in unheated areas like basements and attics spaces. 

Will pipes freeze in one night?

The lower the outside temperature and unprotected water pipes are, the more likely the pipes are to freeze. With very low temperatures and uninsulated pipes, the pipes can freeze overnight.

How quickly do pipes freeze?

Generally, the pipes are expected to freeze within 3 to 6 hours of drawn-out subnormal temperatures. There is a specific threshold below which pipes are in grave danger of freezing and most likely bursting. 

Lowest temperatures to keep pipes from freezing

Not all temperature levels are disastrous to your pipes. You should be worried when the prevailing temperatures fall below 20 degrees Fahrenheit in an unheated house, and the temperature constantly remains low for hours.  Pipes are exposed to freezing even when the temperature lingers above 20 degrees Fahrenheit if openings are letting in the cold air near the pipe’s location.

At what temperature do pipes freeze without heat?

There are activities you can undertake without the heat to keep your pipes from freezing. It is all contingent on how low the outside temperature drops and the amount of time the temperature stays that way.

The temperature is different from state to state making it different to guess the exact temperature to be vigilant to the endangerment of freezing and bursting pipes. As stated by the research overseen by the Building Research Council at the University of Illinois, without heat the temperature threshold for pipes to freeze is 20 degrees Fahrenheit.

Will pipes freeze at 32 degrees?

Water freezes at 32 degrees Fahrenheit, but the indoor pipes, even those in unheated parts of the house like the basement and attic areas, are guarded against the extreme outside temperatures.

Just because the outside temperature is 32 degrees, Fahrenheit doesn’t necessarily mean the pipes will reach those temperatures. For pipes to freeze, the outside temperature must drop to at least 20 degrees Fahrenheit or lower.  

At what temperature should you set your heater to keep pipes from freezing?

Although leaving your heater ON may seem counterintuitive, it can be disastrous if the cold temperatures freeze the pipes and burst them in the process. However, it doesn’t mean you have to keep your home as warm as usual as any temperature of 55 degrees Fahrenheit, or higher is appropriate to keep your pipes safe.

How long does it take a space heater to thaw pipes?

The space heaters can be used to thaw out pipes in 30 to 45 minutes. It’s advisable to get professional help if the pipes burst from the buildup pressure to cause property damage.

Although the space heater can aid in rectifying the situation, preventive measures like insulating the pipes that are highly susceptible to freezing and move outdoor pipes to warmer areas can save you time and money during winter.
