出门度假？热水器应该怎么处理Going on Vacation? What to Do with Your Water Heater

度假时应该关掉热水器吗？以下是节能又不损坏设备的聪明做法，特别是在纽约的冬天。Should you turn off your water heater when going on vacation? Here's the smart approach to save energy without risking damage, especially during NYC winters.

The Vacation Dilemma

Going on vacation? Your water heater will keep heating water 24/7 even though nobody's home. That's wasted energy. But turning it completely off can have consequences, especially in winter.

Best Practices by Season

Summer Vacation (No Freeze Risk)

You can safely:

• Gas water heater: Turn to "Vacation" or "Pilot" mode if available. Otherwise, turn to lowest setting.
• Electric water heater: Turn off the breaker, or set to lowest temperature.
• Tankless water heater: Simply turn off — it only heats on demand anyway. But leave power on for freeze protection.

Savings: $5-$15 per week

Winter Vacation (Freeze Risk!)

⚠️ NEVER fully turn off your heating system in winter. NYC temperatures can drop below freezing, and frozen pipes can burst causing catastrophic water damage. Instead:

• Set thermostat to minimum 55°F
• Set water heater to lowest setting (not off)
• Leave cabinet doors under sinks open to allow heat to reach pipes
• Consider having someone check on your home

Vacation Mode Feature

Many modern water heaters have a "Vacation" or "VAC" setting on the temperature dial. This keeps the pilot lit (gas) or maintains minimal heating (electric) to prevent:

• Bacterial growth (Legionella thrives in warm, stagnant water)
• Freeze damage in cold weather
• Long recovery time when you return

For Extended Absence (1+ Months)

If you're leaving for an extended period:

1. Consider turning off the water supply to the water heater
2. Drain the tank if the home will be unheated
3. Turn off gas or electric supply
4. Have someone winterize the plumbing if needed

When You Return

1. Turn water heater back to normal setting
2. Wait 30-60 minutes for water to heat
3. Run hot water at each faucet to flush stagnant water
4. Check for any leaks that may have developed
