If there are visible obstructions, it is likely that the heat exchanger is clogged and will need to be cleaned or replaced.
Another way to determine if your heat exchanger is clogged is to conduct a temperature differential test. This involves measuring the temperature of the air entering the heat exchanger and the temperature of the air exiting the exchanger. If there is a significant difference in temperature, it could indicate that the heat exchanger is clogged and not functioning properly.
Additionally, performing a pressure test can help identify a clogged heat exchanger. By measuring the pressure drop across the exchanger, you can determine if there is a blockage that is impeding the flow of air or fluid. If the pressure drop is higher than normal, it may be an indication of a clogged heat exchanger that needs attention.
Potential Risks Of A Clogged Heat Exchanger
A clogged heat exchanger can pose several potential risks to your heating system and your safety. One key risk is reduced efficiency, leading to higher energy consumption and increased utility bills.
