Winter Water Heater Maintenance: Tips to Keep Warm Until Spring

March 4, 2025

As winter settles in, ensuring that your home's water heater is functioning optimally becomes crucial. Nothing disrupts the cozy atmosphere of your home quite like a malfunctioning water heater, especially during the chilly months when warm baths and hot showers are at a premium. Here at Chesapeake Bay Plumbing LLC, we understand the importance of maintaining a reliable and efficient water heater. In this post, we’ll share essential tips on winter water heater maintenance to keep your home warm and comfortable until spring arrives.


1. Check the Temperature Setting


The first step in winter water heater maintenance is to check and adjust the temperature setting of your water heater. For optimal performance, the U.S. Department of Energy recommends setting your water heater thermostat to 120 degrees Fahrenheit. This not only ensures you have enough hot water for your needs but also helps save energy. Lowering the temperature setting can minimize the risk of overheating and excessive energy bills.


2. Insulate Hot Water Pipes


One often overlooked aspect of water heater maintenance is the insulation of hot water pipes. Insulating these pipes helps retain heat as water travels from your heater to your faucets, ensuring that your water arrives at the desired temperature. Insulation can also reduce energy costs, keeping your water heater from working overtime to maintain water warmth during transit. Consider using foam pipe insulation or fiberglass insulation sleeves for effective results.


3. Flush the Tank Regularly


Sediment buildup is a common issue in water heaters that can lead to decreased efficiency and even damage over time. This is especially relevant in areas with hard water, which contains high levels of minerals. Flushing your water heater at least once a year can help remove sediment buildup, allowing your system to run efficiently throughout the winter. To do this, turn off the power supply to your water heater, connect a hose to the drain valve, and let the water flow out until it runs clear.


4. Inspect for Leaks and Corrosion


Taking a few minutes to inspect your water heater can save you from costly repairs down the road. Look for any leaks around the unit, as well as signs of corrosion on the tank and connections. If you notice any issues, it may be time to call in a professional plumber to assess the situation and make necessary repairs. Catching these problems early can save you from the burden of a day without hot water or, worse, a replacement water heater.


5. Test the Pressure Relief Valve


The pressure relief valve is a critical safety feature of your water heater that helps prevent excessive pressure buildup. Testing this valve is an essential part of winter water heater maintenance. To test it, simply lift the lever slightly and allow some water to escape. If water flows freely and stops when you release the lever, your valve is functioning correctly. If it doesn’t, consider replacing it to ensure your water heater remains safe and efficient.


6. Schedule Professional Maintenance


While these maintenance tasks can be performed by homeowners, one of the best ways to ensure your water heater operates smoothly through winter is to schedule professional maintenance. At Chesapeake Bay Plumbing LLC, our experienced technicians can conduct a thorough inspection, providing peace of mind that your water heater is ready to handle the winter demands.

Winter water heater maintenance is key to ensuring a warm and comfortable home throughout the colder months. By checking the temperature setting, insulating pipes, flushing the tank, inspecting for leaks, testing the pressure relief valve, and scheduling professional maintenance, you can keep your water heater operating efficiently.
