In fact, you have to add a lot of cold water from that tap to make it tolerable to your skin. When you truly stop to think about it, isn’t it silly to heat water just so that you can add cooler water to it to use it?

Even more silly is the fact that you keep heating it all day long to that 140-degrees even though you aren’t using it other than once or twice per day for showering. The wasted energy is costing you money.

You also don’t want that water standing in the tank at too low of a temperature because it can become a breeding ground for bacteria. Therefore, shutting it off between uses isn’t wise either. 120F is the perfect compromise.

The Right Water Temperature to Save Money and Fight Bacteria


When it comes to choosing a water temperature setting for your water heater, 120F is the perfect one because it is low enough to reduce energy costs while also being hot enough to inhibit the growth of harmful bacteria that could make you or your family sick.

120F is safe but still a good twenty-degrees-Fahrenheit cooler than the 140F that many people set their thermostats at. Twenty degrees can lower your heating costs of water by as much as 6-10%.

For most families, this is going to be somewhere between $10 and $20 per year. While that doesn’t seem like a fortune, there are other things to consider as well.

Water Heater Temperature Contributes to Burns by Scalding

If you have small children, are elderly or have someone living in your home who is, water temperatures of 140F may be hot enough to cause severe burns. Young children are susceptible.

Special needs children and young adults are also prone to hot water heater burns because they may have an inhibited awareness until they are already burned badly. As we age, our skin loses its elasticity and isn’t as protected from burns as it used to be; it also will not heal as readily if you have a skin wound.

Lowering the temperature of your water heater will ensure that no one in your home is unnecessarily burned by hot water that scalds the skin. Water burns are very painful, can blister and get infected.

Available Water Is More Constant


When the water heater is set lower, it doesn’t have to work as hard to keep hot water in the tank.

This means that you won’t have to wait as long between showers if you are a family with several showers to take each evening.

That’s a bonus that everyone at The Plumbing Factory, Inc. will be in agreement with. When the water tank is emptied by two people taking a shower, your wait for hot water won’t take more than a few minutes if your hot water heater is an efficient one.

As you can see, there are many reasons to consider a lower temperature setting on your hot water heater. It’s safer, lasts longer, keeps a more constant supply at the ready and it will save you a few bucks each year. What’s not to love?
