Energy Efficiency

Does turning down the hot water heater save money?

Turning down your hot water heater can indeed save money on your energy bills. By reducing the temperature setting, you decrease the energy needed to heat water, which can lead to noticeable savings over time. This simple adjustment not only cuts costs but also extends the lifespan of your appliance and reduces the risk of scalding.

How Does Adjusting Your Hot Water Heater Temperature Save Money?

Lowering the temperature on your hot water heater reduces the amount of energy required to maintain the water at a constant temperature. Most heaters are set to 140°F by default, but lowering it to 120°F can significantly decrease your energy consumption.

Benefits of Lowering Hot Water Heater Temperature

  • Energy Savings: Reducing the temperature by 10°F can lead to savings of 3-5% on your energy bills.
  • Extended Appliance Lifespan: Lower temperatures reduce mineral buildup and corrosion, prolonging the heater’s life.
  • Safety Improvements: Decreases the risk of scalding, making it safer for children and the elderly.

How Much Can You Save?

The actual savings depend on your water heater’s efficiency and your household’s hot water usage. On average, a family can save up to $60 annually by making this adjustment.

Steps to Adjust Your Hot Water Heater Temperature

  1. Locate the Thermostat: Most water heaters have a thermostat dial on the front. Electric heaters may have two, one for each element.
  2. Adjust the Setting: Turn the dial to 120°F. For electric models, adjust both thermostats.
  3. Check the Temperature: After a few hours, test the water temperature at the tap to ensure it has adjusted correctly.

Is Lowering the Temperature Always a Good Idea?

While lowering the water heater temperature offers many advantages, there are a few considerations:

  • Bacterial Growth: Temperatures below 120°F can promote bacteria like Legionella. Ensure your setting is at least 120°F to prevent this risk.
  • Household Needs: Consider the hot water needs of your household. Larger families or homes with high hot water demand might require a higher setting.

Frequently Asked Questions

What is the recommended temperature for a hot water heater?

The Department of Energy recommends setting your hot water heater to 120°F. This temperature balances energy efficiency and safety, reducing the risk of burns while saving on energy costs.

How often should I check my water heater’s temperature?

It’s a good practice to check your water heater’s temperature every few months. Regular checks ensure it remains at the desired setting and helps identify potential issues early.

Can lowering the temperature affect water pressure?

Lowering the temperature does not directly affect water pressure. However, if you notice a pressure drop, it could be due to other issues like sediment buildup or plumbing problems.

Is it safe to turn off the water heater when not in use?

Turning off the water heater when not in use can save energy, but it might not be practical for daily use. Consider this option if you’re away for extended periods.

How can I maximize my water heater’s efficiency?

In addition to adjusting the temperature, consider insulating your water heater and pipes, performing regular maintenance, and using energy-efficient fixtures to maximize efficiency.

Conclusion

Lowering your hot water heater’s temperature is a straightforward way to save money and improve safety.
