A crack in the heat exchanger can result in a lot of major complications for homeowners. A small crack can result in complications like gas leaks however a major crack can potentially result in a fire. It’s important to have a carbon monoxide detector situated next to your oil furnace. The carbon monoxide detector can easily be installed with a set of cheap tools… My family and I were lucky that we had a carbon monoxide detector in our basement, because we suffered from a leak in our gas oil furnace 2 years ago. The crack in the heat exchanger was quite harsh and the gas leak was sudden. The carbon monoxide detector started going off in the middle of the night when our family and I were sleeping peacefully. I barely heard the sound when I got up to use the bathroom. I still have no idea how long the alarm was sounding before I heard it. If we did not have the alarm, we might not have known there was a leak until there was a major health crisis; Carbon monoxide poisoning can happen actually quickly, especially due to the fact that the gas is tasteless, odorless, and colorless. It is a single of the most significant dangers that can be hiding inside your home… Each year, 100’s of individuals are hospitalized with carbon monoxide poisoning that took place inside the home. If you have a gas oil furnace, I beg you to make sure that your carbon monoxide detector is working well with fresh batteries on a regular basis. It may be the difference between life and death.
