What is a furnace heat exchanger?
A furnace heat exchanger is an essential part of a furnace system, acting as the primary component that helps to transfer the energy from a fuel into the air. It is typically made from sturdy metals such as steel or aluminum, designed to withstand high temperatures and pressure associated with furnace operation. The furnace heat exchangers take in cold air, which circulates around gas burners located inside, creating warmer air. This heated air is then circulated throughout the space, warming up the surroundings efficiently. Without a furnace heat exchanger, furnace systems would be unable to properly transfer fuel energy into heat, making them ineffective and unsafe. Fortunately, they offer reliability and safety when installed correctly.
Why are furnace heat exchangers important?
Furnace heat exchangers are vital components of modern heating systems, as they create a closed circuit that circulates heated air to all home parts without any heat loss. Their purpose is to transfer heat created by combustible gases safely and quickly through the system, making it more energy efficient. Thanks to their sealed construction and advanced design features, furnace heat exchangers provide superior safety and performance while requiring little maintenance. As a bonus, they prolong the life of your HVAC system by keeping temperatures and pressure levels stable throughout. Heat exchangers help keep you comfortable in even the coldest winter months by ensuring your furnace works safely and properly.
Why do heat exchangers crack?
Heat exchangers are responsible for transferring heat from one medium to another, but unfortunately, they are not invincible. Over time, prolonged exposure to extreme temperatures can cause heat exchangers to crack and weaken, compromising heat energy exchange. Poor maintenance practices, including inadequate cleaning and a lack of regular inspection, also explain why these devices break down prematurely. In addition, debris and corrosion caused by various chemical reactions can further degrade the material integrity of a heat exchanger over time, leading to cracks in the tubing or shell that contains it. As such, it is essential to take proper precautions and maintain heat exchangers correctly to avoid costly repair bills due to damage caused by wear and tear.
What are the signs of cracked heat exchangers?
If a heat exchanger has cracked, it should be easy to spot, as there will be a few telltale signs. A common sign of a cracked heat exchanger is boiling and bubbling from the unit. An increase in energy costs is another symptom that the exchanger may be compromised. Lastly, if the water or air around the heating system appears to be discolored or has an increased odor, it can indicate that contaminants are slipping through the exchanger’s walls. Regardless of what type of heat exchange system you are using, if any of these signs appear, then it is time to have your system inspected by a professional as soon as possible.
How can I prevent a cracked heat exchanger?
One way to prevent a cracked heat exchanger is to ensure that your heating system is cleaned and well-maintained. Regularly changing the filter on the heating system will help remove dirt, dust, and other debris that can cause damage over time. Additionally, having an annual maintenance plan for your HVAC system can ensure everything is running efficiently with no issues. As part of this plan, have the technician check for any corrosion or other signs of damage in the heat exchanger itself. When caught early enough, it is possible to replace or repair these problems before they cause more damage or lead to a cracked heat exchanger.
