How Much Gas Does a Pilot Light Use?
The pilot light, a small flame that ignites the main burner of a gas appliance, is an essential component of many household devices, including furnaces, water heaters, and gas stoves. While the pilot light plays a crucial role in these appliances, it is also a significant consumer of natural gas. In this article, we will explore the amount of gas used by a pilot light and what factors influence its consumption.
How Much Gas Does a Pilot Light Use?
The amount of gas used by a pilot light depends on various factors, including the type of appliance, the size of the pilot light, and the efficiency of the device. On average, a pilot light uses around 0.2-0.5 cubic feet of natural gas per hour. This may not seem like a significant amount of gas, but over time, it can add up.
Factors that Influence Pilot Light Gas Consumption
Several factors can impact the amount of gas used by a pilot light:
• Appliance type: Different appliances have varying pilot light sizes and designs, which affect gas consumption. For example, a gas water heater may use more gas than a gas stove.
• Pilot light size: A larger pilot light will use more gas than a smaller one.
• Gas pressure: The pressure of the natural gas supply can also impact pilot light consumption.
• Appliance efficiency: A more efficient appliance will use less gas to achieve the same heating or cooking results.
• Maintenance: Proper maintenance of the appliance and pilot light can help reduce gas consumption.
Pilot Light Gas Consumption by Appliance
Here is a rough estimate of the average pilot light gas consumption for different appliances:
| Appliance | Average Pilot Light Gas Consumption (cubic feet per hour) |
|---|---|
| Gas furnace | 0.2-0.5 |
| Gas water heater | 0.3-0.7 |
| Gas stove | 0.1-0.3 |
| Gas fireplace | 0.5-1.0 |

Cost of Pilot Light Gas Consumption
The cost of pilot light gas consumption varies depending on the location and the price of natural gas. However, as a rough estimate, if you have a gas furnace with a pilot light that uses 0.3 cubic feet of gas per hour, and the cost of natural gas is $1.20 per therm (100,000 BTUs), your pilot light gas consumption would cost around $0.36 per hour. Over the course of a year, this would translate to an annual cost of around $172.80.
Tips to Reduce Pilot Light Gas Consumption
While the pilot light is an essential component of many appliances, there are several ways to reduce its gas consumption:
• Maintain your appliance: Regular maintenance can help ensure your appliance runs efficiently and uses less gas.
• Check the pilot light: Make sure the pilot light is functioning properly and not leaking gas.
• Upgrade to a more efficient appliance: Consider replacing an older appliance with a newer, more efficient model.
• Use a programmable thermostat: Adjusting the temperature on your thermostat can help reduce gas consumption.
• Turn off appliances when not in use: Turn off appliances when not in use to avoid unnecessary gas consumption.
Conclusion
In conclusion, the amount of gas used by a pilot light varies depending on the type of appliance, pilot light size, gas pressure, appliance efficiency, and maintenance. While the pilot light may not seem like a significant consumer of natural gas, it can add up over time. By understanding how much gas your pilot light uses and taking steps to reduce consumption, you can save money on your energy bills and reduce your environmental impact.
