Save on Vacation: How to Turn Off Water Heater When Traveling

Are you a frequent traveler looking to optimize your home's energy efficiency and save on utility bills? One often overlooked aspect is your water heater. Did you know that even when not in use, your water heater consumes energy? This is why it's a good idea to consider turning off your water heater when traveling for extended periods. Let's dive into the details and explore how to do this safely and efficiently.

Before we get started, it's essential to understand that the U.S. Department of Energy recommends lowering the thermostat to 50°F when away from home for an extended period. However, for this guide, we'll explore the process of fully turning off your water heater. This method is suitable for trips longer than a week, as it helps to save the most energy and money.

Understanding Your Water Heater

Water heaters come in various types, but the two most common are gas and electric. The method for turning off a gas water heater differs from that for an electric one. Let's look at each type to ensure you're taking the appropriate steps for your specific water heater.

Additionally, we'll address safety measures to ensure that your water heater functions properly upon your return and remains in good condition during your absence.

What to Consider Before Turning Off Your Water Heater

Before proceeding, it's crucial to address a few points to ensure that turning off your water heater won't lead to any problems upon your return:

• Sediment buildup: If your water has high mineral content, sediment can accumulate at the bottom of the tank. Turning off the heater for extended periods can cause this sediment to harden and make the sediment buildup problem worse.
• Frost protection: If you live in a cold climate, ensure that your water heater's frost protection setting is adjusted accordingly. In some cases, you might need to leave your water heater on to prevent freezing.
• Condensation: During the off-period, water in the cold dip tube (the pipe that brings cold water into the tank) might condense. This can lead to rust, causing issues with your water quality upon return. To prevent this, you can drain a small amount of water before turning off the heater.

How to Turn Off Your Water Heater Safely

Now that you're aware of the potential issues, let's look at how to turn off your water heater safely, depending on its type:

Gas Water Heater:

• First, turn the thermostat dial to "pilot" or "off".
• Then, turn the cold water inlet valve to the "off" position. If you have a water softener, make sure to bypass it as well.
• Finally, turn off the gas supply valve located near your water heater.

Electric Water Heater:

• First, turn off the electrical power supply. Locate the electrical panel that controls your water heater and switch it to the "off" position.
• Next, turn the cold water inlet valve to the "off" position. If you have a water softener, make sure to bypass it as well.

Preparing Your Water Heater for Your Return

To ensure a smooth transition back to normal operation after your trip, it's essential to prepare your water heater for your return:

Gas Water Heater:

• Turn the gas supply valve back on.
• Initiate a "hot water flush" to remove any sediment that may have accumulated at the bottom of the tank. This involves draining a small amount of water from the tank and then refilling it.
• Reconnect your water softener, if you had it bypassed.
• Finally, turn the thermostat dial back to your preferred temperature setting.

Electric Water Heater:

• Turn the electrical power supply back on at the electrical panel.
• Initiate a "hot water flush" to remove any sediment that may have accumulated at the bottom of the tank.
• Reconnect your water softener, if you had it bypassed.
• Finally, ensure that the thermostat is set to your preferred temperature.

After switching everything back on, it may take a few hours for your water heater to reheat the water. Be patient, and don't forget to turn your hot water taps back on after the water heater has finished reheating. With these steps, you'll be back to enjoying hot water in no time!

Turning off your water heater when traveling is an excellent way to reduce energy consumption and lower your utility bills. However, it's essential to take safety measures to prevent potential issues. By following the steps outlined in this guide, you'll ensure that your water heater remains in good condition during your absence and functions properly upon your return. Happy travels!
