Because they used gas all the time unless the pilot was off and the gas valve turned off, they were very inefficient. Great staff and technicians, always timely, love dealing with a family business. After the gas is burned to heat the primary heat exchanger, the secondary heat exchanger draws heat out of the hot exhaust gases, cooling them to the point thatthe water vapor in the exhaust condenses into water. The HSI heats up to around 1,800 to 2,500 degrees Fahrenheit and glows red-hot. Jonathan came in and was very transparent on what they were going to work on. Courteous, efficient, knowledgeable. If you have a newer furnace (or one with an AFUE rating above 80), it most likely has an electronic ignition system. It is this spark that ignites the burners and starts the system. Christopher Jones called and was so helpful with recommendation regarding doing more frequent filter changes. First, the flame must be kept burning at all times. Honest and efficient. Youll not only benefit from having an electronic ignition system, youll have a furnace with superior energy efficiency and a long life ahead of it. Gas Heating for Furnaces and Boilers Basics. Ready for Home Improvement? As you wait, look for the reset button, typically close to the dial you just set to Off., Once the waiting time is over, you should turn the knob to Pilot. Ideally, the gas has dispersed. Not good to have to take a cold shower for work in the morning when its 20 degrees outside. Once the pilot is lit, and the main burner senses the pilot flame (using a flame sensing rod), the main burner ignites. So appreciated. When electrical current flows through it, the metal gets hot enough to ignite the furnace burners. We are very happy with the service we have received from Hydes!

Another ignition system commonly found on furnaces manufactured in the late 1980s through the 1990s are direct spark ignition systems. The ignition system has a safety mechanism that observes the pilot for up to five seconds to ensure that its burning normally. The ignition coil features two windings (primary and secondary). Electric Furnace Open the blower housing and find the reset button. Here are some of the common causes of HSI failure: Most modern furnaces with electronic ignition systems havean integrated circuit board that controls many sophisticated processes. In conclusion, the standing pilot gas ignition system is a safe method of flame proving. Call Today: (908) 707-1776. Intermittent pilot ignition systems are solid-state ignition devices that automatically light a pilot burner. One can still purchase a gas furnace or water heater with the old standing pilot ignition systems. Deactivate the igniter. There are different types of electronic ignition systems, one of which still uses a pilot flame to ignite the gas burners. Turn the meter to the ohms setting (resistance is measured in ohms). : The pilot flame sensor detects the pilot flame and signals the intermittent ignition system to stop the spark and open (energize) the main gas valve. If all is tine, it allows closes the circuitry that allows voltage to pass to the hot surface ignition system. The pilots flame is enough to keep the water in the tank from freezing. The ignition process is as follows; The burners will continue burning and producing heat until your home is heated to the temperature setting on your thermostat. When you pass a strong current through the ignitor, it glows red hot to temperatures over 2500F. Instead of a standing pilot system that stays on throughout, electronic ignition systems use transistors controlled by sensors to generate electronic pulses that ultimately ignite the flame. While the standing pilot gas ignition systems are prone to problems with proper maintenance, the standing pilot gas ignition systems are reliable for many years. Not having a pilot that is continually lit means more efficient operation. One of his specialties is repairing old systems dating back to the 1920s, including galvanized water pipes, knob-and-tube wiring, and more. Electronic furnace ignition systems come with a few important advantages over traditional pilot ignition systems. Natural gas and propane combust spontaneously when exposed to such high temperatures.

They utilize either a thermocouple or thermopile. Due to the spark at the spark plugs tip, the spark will occur. But these pilot lights were often unreliable, and they consumed energy all day and all night, even when the furnace didnt need to run. A pilot light that burns for the whole winter is an additional drain on natural gas, while an electronic ignition system only needs to use power at the moment it ignites the burners. He did a fine job of changing the filters, checking A/C in attic, and outside cooling unit. They were on time, they provided clear estimates, they were professional, and they clearly explained every step of the process to me. They are also significantly safe. This type of electronic ignition uses a small flame to ignite the burners just like a conventional pilot light.
