A heat exchanger is a vital component in your radiator and heating system. The device transfers heat from one area to another so that the desired temperatures are reached and maintained in a room or big rig. It also keeps combustion fumes contained and filtering out of the vent pipe. Below are a few common issues that will help you know when to call a professional for heat exchanger repairs.

5 Regular Heat Exchanger Issues

1. Rust

Over time, condensation can lead to rust and corrosion on the heat exchanger. Moisture around the metal components eats away at the material and usually builds up if there is a blockage near the vent. If your radiator or furnace has a built-in drainage system, rust is more common when condensate lines clog. The best way to stop this issue is to have routine maintenance so that drainage lines are cleared.  

2. Cracks

Cracks and holes can cause a host of problems, such as incorrect temperatures due to escaping heat and carbon monoxide filtering into the area and causing health issues. Cracking can also be the result of overheating. If your filters are clogged, and the airflow is poor, overheating will lead to stress on the metal, requiring eventual heat exchanger repairs, or a replacement.

3. Overloading

The correct load running through the exchanger is vital. Too much, and your radiator suffers from inefficiency and wear and tear. If overloading occurs, you will notice issues such as high temperatures, cracks, and signs of carbon monoxide escaping. Your best bet is to upgrade your radiator to suit your needs and handle the volume necessary for your location.

4. Old Age

Even though heat exchangers are made to handle decades of heating and cooling, the continuous expansion and contraction of the metal will eventually cause it to wear down. This will result in cracks along the vents in your system, which are inevitable. Keeping an eye out for this issue will help you prepare for when you'll eventually need to replace the exchanger.

5. Fouling

Fouling refers to dirt and grime building up and causing an odor that’s comparable to formaldehyde. Chemical changes and organic matter from fluids and corrosion will trigger fouling, and without good maintenance, the problem will only get worse. The best solution is to schedule an annual cleaning.
