Do All Furnaces Have Pilot Lights

For many years furnaces used a small and continuously burning flame known as a pilot light to ignite the burners during every heating cycle.

Do all furnaces have pilot lights. It requires a pilot light to be lit 24 7. All of these problems are not an issue when you have a modern furnace which uses electronic ignition instead of an old fashioned pilot light. There s no pilot light. Some older versions may be spark ignition but still no pilot.

Newer gas furnaces since about 2010 do not have a traditional pilot light that burns all the time. Intermittent pilots still use a pilot light however it isn t a standing pilot light that remains on all the time to ignite the burner whenever the gas turns on. Hot surface igniters and intermittent pilots. The most common part to fail is the hsi.

There are two basic types of electronic igniters in modern furnaces. Constant flame or standing pilot heating systems are still fairly common in older homes and they can still be repaired in most cases. Although pilot lights are still present in homes with older systems most newly installed furnaces use an electronic ignition instead. Most furnaces with electronic ignition have a device called a hot surface igniter.

Louis area homes we want to help familiarize homeowners with them. Today we re going to talk about the difference between conventional pilot lights and electronic ignitions and why there. When the main burner extinguishes the pilot light. One of those technologies is the electronic ignition which replaces the standard pilot light that homeowners have been familiar with for many years.

The small burning flame from the pilot light lights the main burners. A pilot light is a small gas flame usually natural gas or liquefied petroleum gas which serves as an ignition source for a more powerful gas burner originally a pilot light was kept permanently alight but this wastes gas. They have hsis hot surface ignitors. In the recent decades many new technologies have made it possible for furnaces to operate more efficiently than ever.

This is a small electronic device that receives an electrical current whenever your. Unless you have a furnace dating 35years or more no. Now it is more common to light a burner electrically but gas pilot lights are still used when a high energy ignition source is necessary as in when lighting a large burner. Instead the pilot light only comes on when it needs to.

Instead they use electronic ignition systems that light only as needed. Because electronic ignitions are becoming so common in st. Silicone carbide versions.
