WHY? Because...

Water heaters are some of the biggest energy users in the home. That’s why more homeowners—especially those looking to cut utility costs or reduce environmental impact—are taking advantage of a feature known as vacation mode.

So, what exactly is vacation mode, and how can you use it to save money and protect your plumbing?

What Is Vacation Mode on a Water Heater?

Vacation mode is a setting available on many water heating systems that allows the unit to operate at a much lower temperature than usual while you're away. Instead of heating water to the standard 120°F, the system maintains a lower standby temperature—typically around 50°F. This is warm enough to prevent pipes from freezing but cool enough to significantly reduce energy use.

Some water heaters have a dedicated vacation setting on the thermostat, while others may require manual adjustment. Either way, the goal is the same: lower energy usage without risking cold-weather plumbing damage.

How to Set Your Water Heater to Vacation Mode

There are a couple of ways to enable vacation mode, depending on your model:

Using the Thermostat Setting

Check your water heater’s control panel or thermostat. If there's a “Vacation” mode listed, select it. Your system will automatically lower the temperature to a safe, energy-saving level.

Manual Adjustment

If your unit doesn’t have a labeled vacation mode, you can still achieve the same effect by:

Turning the dial to the "Pilot" setting on gas heaters.
Lowering the thermostat temperature manually on electric models.

This reduces heating activity while ensuring your system is ready to come back online when you return.

Why Vacation Mode Matters

Turning down your water heater while you’re away offers two major benefits:

Lower Utility Bills: Heating water when no one is home to use it is simply wasteful. Vacation mode conserves energy and reduces your monthly costs.
Protection Against Freezing: In colder climates, turning the heater completely off can result in frozen pipes. As water freezes, it expands—potentially cracking pipes or damaging the water heater tank itself.

Vacation mode strikes the perfect balance between energy efficiency and winter protection.

How to Reactivate Your Water Heater After Vacation

Once you’re back home, reactivating your system is simple. Here’s how All Hot Water LLC recommends doing it:

For Gas Water Heaters:

Locate the Temperature Dial – Usually near the bottom of the tank.
Set Your Preferred Temperature – 120°F is ideal for most homes.
Allow Time for Reheating – Depending on the tank size, it may take 1–2 hours.

For Electric Water Heaters:

Find the Breaker – Go to your main electrical panel.
Flip the Switch Back On – Restore power to the unit.
Wait for Water to Heat – Be patient as it comes back to temperature.

For Tankless Water Heaters:

Each model is different. Review your unit’s manual to learn how to safely exit vacation mode and restart the heater.

Helpful Reminders from All Hot Water LLC

Check Hot Water Flow – Run your taps to confirm hot water is returning.
Watch for Any Irregularities – If you hear strange noises or notice leaks, it’s best to call in a professional.
Schedule Regular Maintenance – Keeping your system in top shape prevents future issues.
