How much does it cost to run a pilot light?

The cost to run a pilot light typically ranges from $5 to $10 per month, depending on the type of gas used and the efficiency of the appliance. Natural gas pilot lights consume about 700 to 900 BTUs per hour, while propane can be slightly more expensive. Overall, this cost can vary based on local gas rates and the specific appliance's usage. It's a small expense compared to other heating costs, but it can add up over time.
