Step 1 of 2:

What type of water heater do you have in your home? In order to deliver the correct Resource Kit, we’ll need to know if you have an electric water heater or a gas water heater in your home. Select your water heater type below.

Not sure which type of water heater you have?

One of these helpful hints will help you get your answer:

Electric Panel
Look in your electric panel for a circuit breaker tagged WH or water heater. If you see this, it’s an electric water heater.

Label/Tag on water heater
Look on your water heater for a name tag. All water heaters have a name tag which includes:

  • Manufacturer’s name
  • Model
  • Serial #
  • Type of fuel

If it’s electric, it will also have:

  • Voltage
  • Wattage
  • Current (but not always included)
  • Phase

Pipe Type
When you look at your water heater you will see two copper pipes going into the top. Then search for a ½ - 1-inch black pipe going into the bottom of the tank. If you see this black pipe, it indicates your water heater uses natural gas. If you don’t see this black pipe, then you have an electric water heater.

Electrical Cord
Look at the top of the heater for an electrical supply cord. This looks like a thick extension cord and is generally black or gray. If you see one going into the top or side of the heater, it is an electric water heater.

Vent Pipe
Look for a vent pipe on top of your water heater. The presence of a 3 or 4-inch vent pipe indicates a natural gas water heater because the fan and motor inside the water heater force exhaust created by the natural gas out into this vent and outside. Electric water heaters do not have a venting system as there is no exhaust.
