Your Hot Water Tank Temperature Setting
What is the “correct” temperature of hot water tank in your home? Many people wonder if 120 degrees is an adequate temperature setting, or if it should be raised to 140 degrees. The true answer to that is there is no right answer. You are given both choices and both can work, it just depends on a few factors and which setting is the right one for you and your family. To make an informed choice, we decided to list out the main facts below so you can navigate the answer to your needs on your own, as well as a couple further points on how to maintain your hot water supply!

- Your bills will be lower as you won’t pull as much power heating your water
- If it the more environmentally friendly temperature setting for sure

Changing The Temperature Setting

Make sure you have a good read through, including the diagrams so you know what exactly you are doing.
