Introduction:
Rheem Tankless water heaters are popular for homes because they are more energy-efficient than traditional tank water heaters. However, choosing the right temperature setting for your Rheem tankless water heater is important to ensure safety and optimal performance.
This blog post will discuss the recommended temperature setting for a Rheem tankless water heater, how to adjust the temperature setting, and the risks and consequences of setting the temperature too high or too low.
Recommended Temperature Setting For Rheem Tankless Water Heater
The Consumer Product Safety Commission (CPSC) recommends setting your water heater to 120 degrees Fahrenheit. It is the safest temperature to prevent scalding and burns. At 120 degrees Fahrenheit, water takes about five seconds to cause a second-degree burn. At 140 degrees Fahrenheit, water can cause a second-degree burn in just one second. If you increase the temperature above 120 degrees Fahrenheit, you are increasing the risk of scalding and burns. You are also reducing hot water availability and increasing your energy costs.

If you do want to raise the temperature on your Rheem tankless water heater, you can follow these instructions:
- Dial the temperature control up to 120 degrees Fahrenheit.
- Hold the up arrow button until 140 degrees Fahrenheit appears on the display.
- While holding the up arrow button, press the down arrow button. It will lock in the higher temperature limit.

Tips for Choosing the Right Temperature Setting
When choosing the right temperature setting for your Rheem tankless water heater, consider the following factors:
- The number of people in your household
- Your bathing and showering habits
- The climate in your area
If you have young children or elderly adults, keeping the temperature low is especially important to reduce the risk of scalding.
Conclusion
The safest and most efficient temperature setting for a Rheem tankless water heater is 120 degrees Fahrenheit. However, depending on your needs, you may need to adjust the temperature setting. For example, if you have a large household or live in a cold climate, you may need to raise the temperature to ensure enough hot water. If you have young children or elderly adults, keeping the temperature setting low is essential to reduce the risk of scalding. You should also install thermostatically controlled shower valves, which will help to prevent accidental burns. If you need help determining what temperature setting is right for you, consult your manufacturer’s instructions or contact a qualified plumber.
