How to Determine if Your Water Heater Runs on Natural Gas or Propane

To determine if your water heater runs on natural gas or propane, you can check for a pilot light, look for a flue or exhaust pipe, and consult the owner’s manual or model number.

Check for a pilot light

To determine if your water heater runs on natural gas or propane, the first thing you can do is check for a pilot light. This small blue flame is an indicator that your water heater is powered by either natural gas or propane.

Simply remove the access panel of your water heater and look for this pilot light. If you see it, then your water heater is most likely running on either natural gas or liquid propane gas (LPG).

It’s important to note that not all models have a visible pilot light, so if you don’t see one, there are other ways to identify the type of fuel your water heater uses.

Look for a flue or exhaust pipe

To determine if your water heater runs on natural gas or propane, another way to identify the fuel source is by looking for a flue or exhaust pipe. These pipes are typically found near the top of the water heater and serve as ventilation for the combustion gases produced during operation.

If you see a metal pipe extending from the top of your water heater and leading outside, it indicates that your water heater runs on either natural gas or propane. The presence of this flue or exhaust pipe confirms that your water heating system uses one of these two types of gas fuels.
