Adjusting the water coming into your home or apartment is very easy. If the water is set too hot, you could burn yourself at the sink or in the shower (like we do, prompting this post!), too cold and your water runs the risk of bacterial growth. Setting the correct temperature will provide safety from burns and bacteria, not to mention energy savings!
The magic minimum number is 130 degrees. If you are lucky to have the instructions for water heater, the book will show you where 130 degrees is on the tank. If you don’t have that, you can always test the water temperature at your sink.
Get the water going to the hottest temperature possible and put in your kitchen thermometer that you would use when cooking meats. At the tap, the temperature should be 120 degrees; this will give you a tank temperature of 130 degrees.
Now that we know the desired temperature, let’s talk about how to adjust it! The picture below is what you are looking for on your water heater. It will be at the bottom and may be behind a metal plate if you don’t see it right away.

As you can see from the picture here, this is an easy adjustment. Simply turn the dial up or down to adjust the temperature at the tank. Turning clockwise makes the tank hotter. When you are out on vacation, you can even turn the dial to ‘vacation’ or ‘cold’. Lowering the temperature even a little can bring energy savings, from 3% to 5% for every ten degrees!
Good luck everyone and please comment any questions you may have!
