Water heaters provide a dependable supply of warm water through household faucets, fixtures, and appliances. However, cold weather can affect the performance of these plumbing devices, which may interfere with tasks such as bathing, cleaning, and cooking. Fortunately, there are several ways you can keep your water heater fully functional. Below, learn more about common winter issues and how to avoid them. 

How Can Cold Weather Affect Your Water Heater?

Water heaters located in poorly insulated closets or attics may become exposed to cold air during winter. If the tank itself is uninsulated, cold air can lower the temperature of the fluids inside it. When this happens, you might notice lukewarm or even cold water running through your faucets and fixtures. 

When outdoor temperatures drop below 32 degrees Fahrenheit, moisture in uninsulated pipes connected to your water heater can also freeze and expand, causing the tubes to crack or burst. You might notice popping or crackling noises, which are the sounds of water freezing and putting pressure on the pipes. Broken pipes may cause moisture to pool onto your flooring around the heater, leading to serious water damage. In some cases, fluids within the heater may even freeze and expand, causing the tank to burst and resulting in more extensive indoor flooding and damage. 

Additionally, when cool air surrounding the tank lowers its internal temperature, its heating elements may have to work harder to warm fluids to the appropriate temperature. This can cause your heater to use excess energy, resulting in elevated utility expenses. The increased stress on the burners may also cause them to fail prematurely, resulting in the need for professional repairs. 

How Can You Prevent Issues?

Keeping the tank and its components insulated is one of the most effective ways to ensure it remains warm enough to resist freezing. You can do this by wrapping connecting pipes with polyethylene foam or heating tape, which can provide insulation. Additionally, covering the tank with a blanket made from polyurethane foam may provide a barrier that protects warm interior water from the cool exterior air. You can also add insulation to the area of your home that contains your heater, which may prevent the space from becoming cool enough to lower the water's temperature. This can also keep the burners from overworking and using too much energy to warm up water, which may save money on your monthly bills.
