The US Department of Energy recommends setting your hot water heater to 120° Fahrenheit (49°C) for optimum comfort, safety, and energy efficiency. If you are experiencing discomfort with the water being slightly too cold, you can try adjusting the temperature settings up a notch by following these steps:
- Locate your Water Heater
- Turn the hot water dial to adjust the settings (up or down) to your desired temperature.
Note: Storge tank hot water heaters will not show actual temperature settings in degrees (Warm, Standard, Hot, and Vacation).

Having troubles with this step?
If I turn up the setting of my water heater, will I not be using more energy to use Nebia?
Think of your water heater as a kettle. It takes less energy to heat warm water a couple of degrees up rather than emptying the kettle halfway, filling it with cold water, and then heating it back up to the desired temperature. Since Nebia draws little water from your water heater, your water heater won’t need to continuously heat up gallons and gallons of cold water to replenish itself after a water intensive shower. Even if it is at a couple degrees higher, you will still be saving energy with Nebia overall.
