Things To Do When You Spot A Furnace Leakage?

As the winter months approach, your furnace becomes more crucial than ever, as you rely on it to keep your family warm and comfortable. Water pooling around the unit, on the other hand, can be a reason for concern. A water leak from a furnace is a serious possibility, despite its strange appearance. This usually means that something is seeping, leaking, or not draining correctly. The matter may be trivial and easily resolved in some circumstances, but it can also be a big source of stress in others. 

Take a look at the following to better understand your furnace system and learn when to call your local technician:-

Furnace Leakage: Symptoms and Solutions 

1. Condensation Leaks

Do you have a high-efficiency furnace? This usually translates to an Annual Fuel Utilization Efficiency of 90% or greater (AFUE). If you have a high-efficiency furnace, condensation is likely to form. 

Condensation leaks can also be caused by damaged/clogged tubing or a clogged floor drain. When the drainage tube breaks or becomes clogged, a leak occurs. It’s possible that the floor drain is clogged if the tube isn’t. 

Only a high-efficiency furnace, not a standard-efficiency one, would experience condensation. Determine whether your furnace is high-efficiency or low-efficiency by looking at the exhaust pipe. A standard furnace should not condensate because it has a metal exhaust pipe. If there is still condensation after using a standard-efficiency furnace, you should contact a specialist as soon as possible.

2. Malfunctioning Secondary Heat Exchanger 

If condensation isn’t the problem, the secondary heat exchanger could be the one to blame. The repair will be expensive in this scenario, and the furnace may have to be replaced altogether. How do you identify the difference between the primary and secondary heat exchangers? The following are the disparities between the two: 

3. Primary Heat Exchanger 

This component will have the most fierce flue gas near the furnace’s burners. As a result, the heat and flame qualities of the material are more likely to be stressed over time, leading to failure. But, bear in mind that furnaces with an output of 70-80% have only one heat exchanger.

4. Secondary Heat Exchanger 

A primary and secondary heat exchanger can be found in a furnace with a high efficiency of 90% or more. 

As the combustion exhaust departs the first heat exchanger, it is typically routed to a secondary heat exchanger, where more heat is liberated from the flue gas, resulting in the formation of water vapours. 

Latent heat is released in the secondary heat exchanger as the furnace transitions from water to liquid, enhancing the furnace’s efficiency. Steel or coated steel secondary heat exchangers are commonly used because they can endure high temperatures, acids, and moisture.

5. Broken Humidifier 

If none of these components are faulty, the source of the leak could be inside your furnace, notably the humidifier. A trained professional can usually notice a leaking humidifier before it becomes a hassle if you undergo routine maintenance. 

A leaking humidifier can cause considerable damage to the inside of your unit, as well as additional issues such as wall or floor damage, and even mould growth. Calling DEWA Approved Contractors for assistance in detecting and resolving the problem is the simplest approach to fix a leaky humidifier!
