Why Your Water Heater Might Freeze in the Winter

Water heaters can freeze under certain conditions. If temperatures drop low enough, the water sitting inside your heater can freeze, and possibly cause serious damage to the tank and its components. This is especially a concern for outdoor water heaters or those installed in uninsulated areas like garages or basements.

Draining the Water Heater

One of the most effective ways to prevent your water heater from freezing is by draining it during periods of extended inactivity. If you’re planning to be away for a while, draining the tank ensures that no water is left inside to freeze and expand, which could cause cracks or leaks. While refilling your water heater isn’t the most fun task, it beats having to call a plumber for an emergency plumbing repair service because your tank froze and burst.

Letting the Water Run

Another tried-and-true method for keeping your water heater safe from freezing is to keep the water flowing. It doesn’t have to be a gushing stream; just a slight trickle can work wonders. When water is moving, it’s less likely to freeze, especially in frigid temperatures. It may feel like a bit of a waste, but it’s much more cost-effective than dealing with the aftermath of frozen pipes or a damaged water heater.

Adding Insulation

If your water heater is located in a colder part of your home, like the garage, basement, or outside, insulating it is a smart move. Installing a water heater insulation blanket is like wrapping your tank in a cozy winter jacket. These inexpensive blankets can be found at most hardware stores and provide that extra layer of protection your heater needs when the temperatures dip below freezing. It’s also a good idea to insulate the pipes leading to and from the water heater. Pipes are vulnerable to freezing, and pipe insulation can be an easy, affordable way to keep the water flowing. If you’re not sure what type of insulation to use, reach out to a plumber for guidance.

Installing a Hot Water Recirculation System

If you want a more permanent solution to keep your water heater from freezing, consider installing a hot water recirculation system. This system keeps hot water moving through your pipes, which prevents freezing and reduces the time it takes for hot water to reach your taps. While installing this system might sound complex, it’s something a professional plumbing service can handle easily. You’ll always have hot water on demand and peace of mind knowing your system is protected from freezing.

Location, Location, Location

Sometimes, the best prevention is installing your water heater in the right place to begin with. If you live in a cold area, your heater should be installed in a warmer part of your home, away from drafts or uninsulated walls. If your current water heater is installed in a less-than-ideal location, it might be time to consider a water heater replacement. Moving your heater to a more protected spot could save you from dealing with future freeze-ups.

Investing in Freeze Protection

If you’re in the market for a new water heater, look for models that come with built-in freeze protection. Some newer water heaters are designed with freeze-resistant features, such as automatic heat tracing or insulation that protects the internal components from extreme cold. Although these models may cost more upfront, they can save you a ton of hassle in the long run, especially if freezing temperatures are a regular occurrence where you live. If you’re not sure which model is best for your home, ask a plumbing specialist for advice.
