The Best Water Heater Temperature Settings to Save Money

There are great efficiency opportunities with your hot water system.

water heater Norfolk, MAWhen you think about the biggest energy consumers in your home, heating and cooling equipment probably come to mind first. But here’s something worth considering: your water heater rivals those systems as one of your home’s largest draws on energy, accounting for nearly one-fifth of the average household’s annual energy use. Unlike your furnace or air conditioner, your water heater runs every single day of the year. That means the opportunities to save energy and money with smart temperature management are significant.

A few simple adjustments could make a meaningful difference on your monthly bills without sacrificing the hot water your household depends on.

How to Find and Adjust Your Water Heater’s Thermostat

Before you can optimize your settings, you need to know where to make the adjustment. The thermostat on most traditional tank water heaters is located at the top or bottom of the unit, typically tucked behind an insulated access panel. Once you locate it, adjusting the temperature is straightforward.

Turn Down the Factory Setting

Most water heaters ship from the manufacturer preset to 140°F. That’s hotter than necessary for most households, and it comes with real downsides:

Dropping your thermostat to 120°F is one of the simplest efficiency improvements you can make. This adjustment, paired with basic water conservation habits, can save you up to $400 per year. It also still delivers water hot enough to eliminate harmful bacteria while meaningfully reducing the risk of accidental burns.

Adjust Settings When You Travel

If you’re heading out of town, there’s no reason to keep heating a full tank of water that no one will use. Before you leave:

This small habit can add up to real savings over multiple trips throughout the year.

Tankless Water Heater Settings

If your home has a tankless water heater, you have even more flexibility and potentially even greater efficiency gains. Tankless units heat water on demand, which means you can often run them at a lower base temperature than a conventional tank without sacrificing comfort.
