My parents heating system has been around for the longest time I can remember; I found it working over 30 years ago… Unfortunately, the heating system in my own modern home seems to be failing on me, thinking about the fact that the exchanger broke, yet it is relatively new, then what could be the reason behind this, however I still had expected it to serve me as long as my Grandma’s did? A good amount of research on this subject leads me to some interesting findings. It turns out that the heat exchanger may have broken for various reasons, and one of the main issues might have been nasty filters. I am guilty of leaving my heating system filters unchanged for years because I did not remember replacing them at any point. It is possible that they jammed over time and, as such, hindered free airflow, consequently, this may have come with certain overheating, which then caused the exchanger to crack, my Heating as well as A/C professional confirmed this plus recommended that I should update the filters every month to be on the safe side. Other reasons that may also bring on exchanger concerns include an oversized heating system, and this means that the heating system is likely to heat the modern home too fast, starting the temperature control, which then shuts down, then frequent heating unit cycles caused by huge or insufficient heating system sizes may lead to expansion plus contraction of the heat exchanger, which puts stress on the exchanger, causing it to crack. The heat exchanger should be treated carefully, considering its importance to the heating process. Without it, the heating system is useless. Talk to the heating system service experts if the exchanger cracks. They are likely to command you on better management plus care.
