Understanding How A Hot Surface Igniter Works

Once upon a time, more or less every residential gas furnace was equipped with a pilot light to accomplish the task of ignition. Now, however, more and more furnaces utilize a so-called hot surface igniter instead. This component utilizes electrical energy to start off the process of combustion. In this article you will learn more about how a hot surface igniter accomplishes this task.  Sequence Of Events The first thing that happens when your furnace receives a call for heat is that the induced draft motor starts up. This ensure that, once combustion has started, the exhaust by-products will be safely vented out of your home. A sensor then reports that the motor has successfully started, thus allowing the process to continue.  This is where the hot surface igniter comes into play. The furnace’s control board allows electrical energy to flow to the igniter, which can soon be seen glowing red hot....

Advantages of Installing Ductless Cooling and Heating Systems

If you are thinking about replacing your air conditioning or heating system, consider installing a ductless one. Ductless systems don’t use ductwork and are easier to install, save energy, are more flexible, and are more fashionable. They come in two varieties: Mini-split systems, where one indoor unit is connected to a single outdoor condensing unit, and multi-split systems, where several indoor units are connected to a single condensing unit (unlike traditional systems, where several outdoor units are needed). Having a mini-split system means that you can control the temperature of each room or zone independently. Instead of heating up your whole floor, you can heat up or cool off only the room you are using. This will cut down your energy costs significantly. And did you know that more than 30 percent of your energy usage can be wasted on air escaping the ductwork in places you don’t frequent, such as the...
