One of the things that many homeowners fail to realize is that it is entirely possible to set and optimize the temperature of their water heater. In light of that fact, the water heater experts here at Marti’s Plumbing Service have put together this water heater temperature optimization guide.

By following our guide, you should have no problem changing the temperature of your water heater. We’ll also discuss the different use-cases that determine the optimum water heater temperature for your needs. So, without further ado, let’s get started!

Optimal Temperature Settings for a Variety of Specific Use-Cases

Determining your optimal water heater temperature is, often, as easy as knowing what you use your water heater for the most. In other words, different uses for hot water designate the temperature said water should be for optimal performance.

To make things a little less confusing, our water heater professionals have put together a list of common water heater use-cases and their optimal temperature settings. Let’s break them down:

Commercial Kitchen
If you run or work in a commercial kitchen, then your hot water needs to be hot enough to sanitize dishes. For these situations, water heaters should be set to around 140 degrees Fahrenheit.

Home With Children or Elderly Bathers
However, if you live in a house with children or elderly people who have access to hot water, then the optimal temperature is about 120 degrees Fahrenheit. Setting your water heater higher can result in burn injuries and scalding.

Home With Someone With Respiratory or Immune System Disorders and Illnesses
If you live in a home where you or another occupant has a severe respiratory disease or immune disorder, then set your water heater to 140 degrees. Temperatures lower may harbor bacteria and viruses that are harmful to those with respiratory or immune system problems.

Adult Home
If you live in a home with nothing but adults, then you should set your water heater however you like.

How to Find Your Optimal Water Heater Temperature

Okay, if you don’t live in a home with a commercial kitchen, children, or the elderly, then, as we said above, you’re free to set your water heater to whatever temperature you like. Just remember that setting your water heater lower than 120 degrees Fahrenheit provides a breeding ground for bacteria and that temperatures over 140 can damage your water heater or cause serious burn injuries.

To figure out your optimal water heater temperature, simply do the following:

  • 1: Locate the thermostat for your water heater.
  • 2: Set the water heater thermostat to 120 degrees.
  • 3: Wait an hour and then test the temperature. If you like it at 120 degrees, then leave it, and you’re done. However, if you don’t want 120 degrees, then move on to step 3.
  • 4: Increase the temperature in ten-degree increments — waiting an hour and testing each time — until you arrive at your optimal temperature.
