What Is A Heat Exchanger?

What Is A Heat Exchanger?

Maintaining warm or cool air inside a commercial property or inside an appliance that must process air for optimal function is part of an intricate process. Therefore, several complex components typically play a role in executing these efforts. One such item is known as a heat exchanger.


Though a heat exchanger is often featured in numerous devices, said items are most noted for being integral furnace components. These devices transmit heat from one location to another.

Operational Process

Furnaces burn fuels like natural gas or propane to ultimately create the heat that warms a building. When these substances enter a heat exchanger, the metal comprising the device is heated and the gases exit the furnace.

As this process completes, heated metal warms the neighboring air. This air is then transmitted out of the furnace and the heating of the structure’s interior can commence.

Potential Malfunctions

Aging or deterioration of a heat exchanger could result in structural problems like holes or cracks. Should this situation occur, several significant issues might result.

First, the air warming process could be inhibited, which could limit a furnace’s capacity to keep an interior location comfortable.

That said, should the crevices or holes grow pronounced enough, the heating gases could mix with open air. Such events may lead to a potentially dangerous phenomenon called incomplete combustion. This event could precipitate the formation of a harmful, potentially fatal substance known as carbon monoxide.

Associated Problems

Furnaces processing carbon monoxide are dangerous to operate. Eventually, heat exchanger damage will only worsen and this hazardous gas will ultimately be transmitted into your living or working spaces.

When exposed to smaller concentrations or in its earliest stages, carbon monoxide exposure often produces few, if any, physical manifestations.

However, as you continue to inhale the substance, symptoms like dizziness, lightheadedness, balance issues, cognitive decline, and vision problems might occur. Should excessively high levels of the gas circulate through the air, you could lose consciousness within a matter of hours.

Signs Of A Heat Exchanger Malfunction

Occasionally, heat exchanger malfunction or deterioration might be indicated through signs such as the presence of soot on the furnace, damage to other furnace components, unusual odors, and visible water leaks surrounding the furnace.

That said, in many instances, tiring heat exchangers do not produce any of the preceding problems and issues can only be detected by an experienced heating and plumbing professional.

Should a heat exchanger in Addison TX be damaged, a furnace is considered too dangerous for you to operate. In response, an examining professional will likely power the apparatus down and make the necessary repairs or replacement.

Industry insiders also recommend that you install carbon monoxide detectors as additional protection.
