Save Money by Adjusting Your Water Heater’s Temperature This Winter

Adjusting your water heater temperature during the winter can be a practical way to save energy and enhance comfort. Here’s why and how:

Why Adjust Your Water Heater in Winter?

  • Compensate for Colder Inlet Water: During winter, the water entering your home is much colder. Your water heater works harder to heat it to the same temperature. Increasing the water heater setting can maintain consistent hot water temperatures for your daily needs.
  • Improve Comfort: A slight temperature increase can ensure your showers and baths are warm and cozy, especially in colder months.
  • Energy Savings: While it seems counterintuitive, optimizing your water heater’s temperature (instead of keeping it too low or excessively high) can reduce energy loss, making the system more efficient.

Recommended Temperature Settings:

  • Default Setting: Most water heaters are set to 120°F (49°C), which is safe and energy-efficient for most households.
  • Winter Adjustment: Increase the temperature to about 130°F (54°C) if you notice lukewarm water. However, always ensure it doesn’t exceed 140°F (60°C) to avoid scalding risks.

Additional Energy-Saving Tips:

  • Insulate Your Water Heater and Pipes: Adding insulation reduces heat loss and keeps water hotter for longer.
  • Use Less Hot Water: Install low-flow showerheads and fix leaks to reduce hot water consumption.
  • Upgrade to Energy-Efficient Models: Consider a high-efficiency model, such as a tankless or heat pump water heater.
