How to Turn Off Your Water Heater — Barre, Vermont
Complete checklist with climate-adjusted recommendations for Barre, Vermont
Overview
For gas: set to pilot or vacation mode. For electric: turn off at the breaker. Drain the tank if the home will be unheated.
Step-by-Step Guide
Identify your water heater type
Determine whether you have a gas or electric water heater. Gas units have a gas line, a burner at the bottom, and a vent pipe on top. Electric units have no gas line and connect to a dedicated 240V circuit. Tankless units have a separate procedure — check the manufacturer's manual.
For gas: set to Pilot or Vacation mode
Locate the temperature dial on the front of the gas control valve (usually near the bottom). Turn it to 'Pilot' to keep the pilot light running (recommended for short vacations) or to 'Vacation' mode if available. This prevents the burner from firing while keeping the pilot ready for your return.
For gas (extended absence): turn off the gas valve
If you are shutting down the home for an extended period, close the gas shut-off valve on the gas supply line to the water heater. The valve handle should be perpendicular to the pipe when closed. You will need to relight the pilot when you return.
For electric: turn off the circuit breaker
Open your electrical panel and locate the breaker labeled 'Water Heater' — it is typically a double-pole 30-amp breaker. Flip it to the OFF position. Place a piece of tape over the breaker with a note so no one accidentally turns it back on.
Turn off the cold water supply to the heater
Locate the cold water inlet valve on top of the water heater (usually on the right side). Turn it clockwise to close. This prevents water from flowing into the tank while you are away and avoids potential leaks from an unmonitored tank.
Drain the tank if the home will be unheated
Attach a garden hose to the drain valve at the bottom of the tank. Route the hose to a floor drain, sump pit, or outside. Open the drain valve and a hot water faucet upstairs to allow air in. Let the tank drain completely — a 40-gallon tank takes 20–30 minutes.
For tankless units: follow manufacturer instructions
Tankless water heaters require a different shutdown procedure. Typically: close the gas valve or turn off the breaker, close both hot and cold isolation valves, and remove the drain plugs to empty residual water. In freezing climates, the built-in freeze protection only works if the unit has power.

Safety Tips
- Never turn on an electric water heater when the tank is empty — the exposed heating elements will burn out immediately, requiring replacement.
- When draining a gas water heater, the water coming out may be extremely hot. Direct the hose away from people, pets, and plants.
- If you smell gas at any time while working near a gas water heater, do not flip any switches. Leave the area immediately and call your gas utility from outside the home.
- When relighting a pilot, follow the manufacturer's instructions exactly. If the pilot does not light after two attempts, close the gas valve and call a technician.
When to Call a Professional
Call a plumber if the drain valve is stuck or leaking, if you smell gas, if the gas control valve is malfunctioning, or if you are unsure how to relight the pilot. For tankless units with complex isolation valve setups, a professional winterization visit is worthwhile.
Pro Tip
When you return and refill the tank, open a hot water faucet upstairs and let water run from it before turning the heater back on. This confirms the tank is full — air pockets are pushed out through the open faucet. Once a steady stream flows, close the faucet and turn on the heater.
Common Mistakes to Avoid
- Turning off the electric breaker but forgetting to turn off the water supply, leaving the tank at risk of leaking unmonitored.
- Draining the tank without turning off the power first, which burns out the heating element (electric) or overheats the tank (gas).
- Turning the electric heater back on before the tank is completely refilled with water.
- Forgetting to close the drain valve before refilling — water floods the utility area.
- On gas units, turning the knob past 'Pilot' to 'Off' when 'Vacation' mode would have been sufficient, requiring a pilot relight on return.
