Should I Turn Off My Water Heater When I Go on Vacation?
Before leaving for vacation, most homeowners remember to lock the doors, hold the mail, and adjust the thermostat. But what about the water heater?
If you’re going to be away for several days or longer, you may wonder if turning off your water heater can save energy and money. The answer depends on how long you’ll be gone and the type of water heater you have.
In many cases, lowering the temperature or using vacation mode is a better option than completely turning the unit off. Here’s what Kentucky homeowners should know before heading out of town.
Why Adjust Your Water Heater Before a Trip?
Your water heater keeps water hot so it’s ready whenever you need it. Even when no one’s using hot water, the system still uses energy to keep the water warm.
If you’ll be away for a while, reducing that energy use can help lower utility costs and avoid wasting energy.
Many newer water heaters have a vacation setting that lowers the water temperature while keeping the unit running safely.
Benefits of Turning Down Your Water Heater
For longer vacations, adjusting your water heater can offer a few benefits.
Lower Energy Use
Since nobody will be home using hot water, there’s no need for the system to work as hard. Lowering the temperature can reduce energy use while you’re away.
Lower Utility Bills
The savings may not be huge, but they can add up if you’re gone for a week or longer.
Less Wear on the System
Running the water heater less often may reduce some wear on parts over time.
Things to Think About Before Turning It Off
Completely turning off your water heater isn’t always the best choice.
It Takes Time to Heat Back Up
When you return home, the water heater will need time to heat the water again. Depending on the tank’s size, that could take a few hours.
Different Systems Have Different Requirements
Gas and electric water heaters aren’t shut down the same way. It’s important to follow the manufacturer’s instructions.
Older Units May Not Benefit as Much
Some older water heaters do better when they’re left running normally. If your system is already showing signs of wear, shutting it off and restarting it may not be necessary.
What Should You Do for a Short Trip?
If you’re only leaving for a few days, it’s usually fine to leave the water heater on.
The amount of energy you’ll save during a short trip is often small. Instead, you may want to lower the temperature slightly or use vacation mode if your unit has that feature.
What About Longer Vacations?
If you’ll be away for a week or more, adjusting the water heater may make more sense.
Common options include:
- Using vacation mode
- Lowering the temperature setting
- Turning off an electric water heater at the breaker
- Following the manufacturer’s instructions for shutting down a gas water heater
Always check your owner’s manual before making changes to your system.
Safety Tips Before Leaving Your Water Heater Unattended
Whether you decide to leave your water heater running or adjust the settings, a few simple precautions can help prevent problems while you’re away.
Check for Signs of Leaks
Before leaving, look around the water heater for standing water, rust, or moisture. Even a small leak can become a larger problem if it goes unnoticed for several days.
Follow Manufacturer Recommendations
Every water heater is different. Some models have a vacation mode, while others may have specific instructions for lowering the temperature or shutting the system down. Always follow the manufacturer’s guidelines.
Don’t Shut Off a Gas Water Heater Improperly
If you have a gas water heater, avoid turning it off completely unless you’re familiar with the proper procedure. Incorrect shutdown or restart procedures can lead to operational problems.
Enjoy Your Vacation With Peace of Mind
Turning down your water heater can be a smart way to save energy while you’re away. For many homeowners, using vacation mode or lowering the temperature is the easiest option. The right choice depends on your water heater and how long you’ll be gone.
