Lower water heater energy use while you’re away
Water heaters can use more energy than you may realize, even when no one is using hot water. Managing your water heater while you’re away can lead to noticeable savings on your electricity or gas bill.
Water heater shutdown vs. temperature reduction
A shutdown stops the water heater from using energy altogether, while a temperature reduction lowers energy use without fully turning the system off. Before leaving for your trip, adjust your water heater based on how long you’ll be away:
- For trips longer than 3 days, some Texas homeowners choose to turn off their water heater entirely.
- For shorter trips, keeping your water heater's temperature at or above 120-140°F helps prevent bacterial growth while maintaining efficiency.
Tankless systems, which are common in newer homes in Texas, usually allow scheduled temperature adjustments with the use of an app or control panel. During winter, don’t shut off water heaters completely in case your pipes freeze. Instead, reduce the temperature to prevent potential damage.
Smart water heater controls and scheduling
Smart water heaters make it easy to manage settings even if the weather in Texas flips from warm to freezing while you’re gone. Common features include:
- Remote shutoff from your phone or smart home app
- Customizable temperature schedules for weekdays, weekends or vacation periods
- “Vacation Modes” that automatically lower energy use during extended absences
- Energy monitoring to see exactly how much you’re saving
Combined with HVAC and appliance strategies, taking these actions can contribute to meaningful energy cost savings, even while you’re away.
What to keep connected
Not every device should be disconnected. Some should stay on to keep your home safe, secure and functional, such as:
- Essential lighting timers
- Refrigerators and freezers
- Security systems
- Smart locks and cameras
- Wi-Fi routers (if using remote monitoring)
For extended getaways, consider emptying the fridge and pulling the plug on any secondary refrigerators or garage freezers to save additional energy.
