How to Prepare Your Water Heater for Cold Weather

As winter approaches, ensure your water heater is ready to handle the colder temperatures. A well-prepared water heater can prevent issues like freezing pipes, decreased efficiency, and unexpected breakdowns. Here are key steps to prepare your water heater for cold weather and keep your home comfortable throughout the season.

1. Check the Temperature Setting

Before you find yourself standing beneath a cold shower, you may want to slightly increase your water heater’s temperature setting. 

Adjusting the temperature setting on your water heater can enhance its performance during colder months. The recommended temperature for optimal performance is around 120°F. This setting saves on energy costs while still providing safe and sufficient hot water.

Depending on how your water fixtures and pipe insulation, you may feel the need to raise the temperature even higher in the winter. While you know your home best, proceed with caution to avoid overheating. Additionally, if you take this step, you must lower the temperature once the weather starts heating up. Otherwise, you could risk scalding, especially for older adults and young children. Read our guide to raising water heater temperatures here. 

2. Drain and Flush Your Water Heater’s Tank

Regular maintenance, including draining and flushing your water heater, is crucial for its efficiency and longevity. This process removes harmful sediment buildup, which can affect water heater performance. Sediment is especially prominent in areas with hard water, like Sacramento. A professional will complete this service during a routine maintenance visit to keep your unit working throughout the winter season.

3. Replacing Old Sacrificial Anode Rods

Your water heater needs all the help it can get to survive the winter season. Thankfully, it has a sacrificial anode rod on its side. 

The sacrificial anode rod plays a key role in protecting your tank from corrosion.  You can read about the anode rod’s purpose and function here. Having a professional routinely replace this rod can extend the lifespan of your water heater. This process can also help address other issues, like smelly water. If your rod is 2-4 years old, consider replacing it before the winter season hits. 

4. Consider Adding a Heat Trap

A heat trap can enhance the efficiency of your water heater, especially in colder weather. This device prevents hot water from flowing back into the cool water line. Many newer water heaters already include a heat trap, but adding one to an older unit may help boost efficiency and longevity. Your plumbing professional can tell you if you need a heat trap and explore your options for this service.

5. Prepare and Monitor for Leaks

Cold weather can cause pipes to contract, leading to potential leaks throughout your plumbing system —  including your water heater. 

First, take measures to prevent leaks, such as winterizing your outdoor plumbing.

Throughout the winter, you will want to regularly check your home for signs of water leaks. It is essential to know where your main water shutoff valve is and how to switch it in the case of a plumbing emergency. If you suspect a leak, immediately turn off your home’s water and call a professional.
