Introduction to Furnaces and Pilot Lights
A furnace is a heating system that uses fuel, such as natural gas or propane, to warm up your home. At the heart of every furnace is a pilot light, a small flame that ignites the fuel to produce heat. The pilot light is a critical component of the furnace, as it provides a constant source of ignition for the burners. In the past, pilot lights were always lit manually, but with the advancement of technology, many modern furnaces have automatic ignition systems.
How Pilot Lights Work
A pilot light is a small, continuous flame that burns inside the furnace. Its primary function is to ignite the main burners when the thermostat calls for heat. The pilot light is typically fueled by a small amount of gas, which is regulated by a valve. When the thermostat signals the furnace to turn on, the pilot light ignites the main burners, which then produce heat. The pilot light remains lit even when the furnace is not in use, as it’s necessary to provide a constant source of ignition.
Types of Pilot Lights
There are two main types of pilot lights: standing pilot and electronic pilot. A standing pilot is a traditional pilot light that remains lit at all times, even when the furnace is not in use. An electronic pilot, on the other hand, is an automatic ignition system that only lights the pilot when the furnace is turned on. Electronic pilots are more energy-efficient and safer than standing pilots, as they eliminate the risk of a constant flame.
