Understanding Water Heater Temperature

Most water heaters are set to 140°F (60°C) by default, which is hotter than most households need. Lowering this temperature can lead to significant energy savings and reduce the risk of scalding.

Why Lower Your Water Heater Temperature?

  1. Energy Savings: Reducing the temperature by just 10°F (about 5.5°C) can save you 3-5% on your energy bill.
  2. Safety: Lowering the temperature helps prevent accidental burns, especially for children and the elderly.
  3. Environmental Impact: Using less energy reduces your carbon footprint, contributing to a healthier planet.

How to Adjust Your Water Heater Temperature

Here’s a simple step-by-step guide to help you adjust your water heater temperature:

  1. Locate the Temperature Dial: Most electric water heaters have a dial on the front, while gas water heaters often have a thermostat behind a removable panel.

  2. Check the Current Setting: Use a thermometer to check the water temperature at the tap. This will give you a baseline for adjustment.

  3. Adjust the Temperature:

    • For electric heaters, turn the dial to a lower setting, ideally between 120°F (49°C) and 130°F (54°C).
    • For gas heaters, use a flathead screwdriver to adjust the thermostat to the desired temperature.

  4. Test the Water Temperature Again: After waiting a few hours, turn on the hot water tap and use a thermometer to check if the temperature is now at the desired level.

Practical Examples

  • Example 1: If your water heater is currently set to 140°F and you lower it to 120°F, you could save around \(36 to \)61 annually on energy costs.
  • Example 2: A family of four that reduces their water heater temperature to 120°F will not only save money but also reduce their risk of scalding, especially for young children.
  • Example 3: If you live in a warmer climate, consider setting your temperature even lower, at around 110°F, which can still provide adequate hot water for tasks like showering and dishwashing while maximizing savings.

Final Thoughts

Reducing your water heater temperature is a simple yet effective way to save energy, cut costs, and promote environmental sustainability. By making this small adjustment, you can enjoy hot water without the extra expense or risk. So, why not give it a try today?
