A pilot light, a small, continuously burning flame used to ignite the main burner in appliances like furnaces and water heaters, consumes a measurable quantity of natural gas. This consumption, while seemingly minimal on a daily basis, can accumulate over time. For example, a standard gas appliance pilot light might use approximately 4-5 therms of natural gas per month. This can represent a significant portion of a household’s overall gas bill, especially in older appliances with less efficient pilot light systems.
Understanding the energy consumption of these small flames is critical for optimizing energy efficiency and managing utility costs. Historically, pilot lights were the standard ignition method. However, with the advent of electronic ignition systems, the ongoing energy consumption associated with a standing pilot light has become a factor in appliance selection and household energy audits. Reducing this constant gas usage can contribute to both financial savings and a reduction in greenhouse gas emissions.
