Water Heater Temp: Energy Savings & Safety Tip This Week

August 12, 2026 · AcRepairTechnician Pros News Desk

TL;DR: Adjusting your water heater temperature can save energy and improve home safety. Here's how to do it practically this week.

This week, a practical step you can take to boost your home’s efficiency and safety involves a simple adjustment to your water heater. According to Real Simple, setting your water heater to the right temperature is key, offering a dual benefit of energy savings and enhanced household security. Many homeowners may not realize the impact this setting has. Too high a temperature wastes energy as the water heater works harder to maintain it, leading to higher utility bills. On the other hand, a temperature that's too low can pose health risks, particularly for children and the elderly, by not effectively killing bacteria. For most households, a temperature between 120°F and 125°F is recommended. This range strikes a balance between preventing scalding injuries and ensuring the water is hot enough for most common uses, while also helping to inhibit the growth of harmful bacteria. This is a straightforward adjustment that can be made with minimal effort. To implement this change, locate the thermostat on your water heater. It's usually a dial or a set of buttons. Carefully adjust it to the desired temperature. It’s a good idea to use a thermometer to confirm the water temperature at a faucet a few minutes after making the adjustment. This ensures accuracy and safety. Taking this proactive step this week can contribute to lower energy consumption and a safer environment for your family. Remember, if you encounter any issues with your water heater or need assistance with plumbing-related tasks, licensed and insured professionals are available to help. For those in and around Chicago, Illinois, if an unexpected water heater issue arises and you require emergency service, reaching out to a qualified local expert is a wise choice.
