WHAT IS THE BEST WATER HEATER TEMPERATURE TO SAVE ENERGY? – Experienced Residential Plumbing Services in Springfield, MO

With rising energy prices worldwide, homeowners must continuously seek ways to save on utility bills, and water heater repair or maintenance plays a crucial role in achieving this. Adjusting your water heater temperature can significantly reduce energy consumption and lower monthly expenses. 

In this post, our plumbing experts will reveal the most energy-efficient water heater temperature and share their tips for optimal water heater installation .

How Does Water Heater Temperature Impact Energy Consumption?

It’s vital to understand how water heater temperature impacts energy consumption. The higher the temperature, the more energy it takes to maintain that level. Thus, lowering the temperature even slightly can make a substantial difference in your energy bill.

What is the Best Water Heater Temperature to Save Money?

The U.S. Department of Energy recommends an ideal water heater temperature of 120ºF (49ºC). This temperature is sufficient to eliminate bacteria and prevent harmful pathogen growth while remaining energy-efficient. Additionally, maintaining a 120ºF temperature helps prevent scalding injuries from accidental hot water exposure.


If your dishwasher lacks a booster heater, you may need to increase your water heater temperature to 140ºF (60ºC) to ensure proper dish sanitation. However, most modern dishwashers include booster heaters, so this adjustment may be unnecessary.

More Tips For Energy-Efficient Water Heater Installation 

Besides temperature adjustments, other factors in your water heater installation can help reduce energy consumption and save on utility bills:

  • Insulate your water heater: Insulating your water heater with a blanket or insulation sleeve can decrease standby heat loss, which is the heat that escapes from the water heater into the surrounding area.
  • Use low-flow showerheads and faucets: By installing low-flow showerheads and faucets, you can decrease hot water usage, thereby reducing energy consumption.
  • Promptly fix leaks: Addressing even small leaks quickly can conserve hot water over time, saving on your energy bill and preventing water damage.

It’s also essential to consider the type of water heater you have, as various models are available, including tankless, heat pump, and solar water heaters. Each type offers unique advantages and disadvantages regarding energy efficiency.

  • Tankless water heaters are highly energy-efficient, as they only heat water on-demand, avoiding the energy waste associated with maintaining a constant temperature like traditional tank water heaters. However, tankless models can be more expensive to install and may not accommodate the hot water demands of larger households.
  • Heat pump water heaters represent another energy-efficient option. They use electricity to transfer heat from the surrounding air or ground to heat water. While heat pump water heaters may cost more upfront, they can save homeowners significantly on energy bills in the long run.

  • Solar water heaters harness the sun’s power to heat water and are highly energy-efficient. However, they can be more expensive initially and require ample sunlight to function correctly.

Keeping Your Water Heater Running Efficiently

Regardless of your water heater type, scheduling regular maintenance is crucial for efficient operation. Maintenance tasks include flushing the tank, checking the pressure relief valve, and inspecting the anode rod. Proper water heater care extends its lifespan and ensures peak efficiency.
