Many people do not realize that every day there is a machine in your home that is generating tons and tons of poisonous gases. What machine are we talking about? Your furnace, boiler, and hot water tank! Each of these units must create combustion in order to create heat. Combustion produces harmful gases that if released into the breathing air of your home can make you sick or kill you. If all is installed and is working properly then combustion gases should be vented to the outdoors where they can disburse. But, what is something goes wrong?
Let’s look at how a central air gas powered furnace should work. The inducer motor is a part of the furnace that will vent out the gases that are created by combustion. It first brings in air from the outdoors to combine with gas. Once combustion is created, the burners in the furnace will ignite and transfer heat to the heat exchanger. The heat exchanger is important because it creates a wall between the combustion chamber (burners, inducer motor, and gas valve) and the air that is coming into the furnace from all over the home to be warmed and then re-circulated. When all is working properly, the inducer motor should be venting the bad gases outside while the heat exchanger is protecting your breathing air from contacting the combustion gases.
Some of the combustion gases include:
- Carbon monoxide
- Nitrogen oxides
- Sulfur oxides
The Two Major Problems
The first major problem that is often encountered deals with the heat exchanger. As time passes, the constant heating and cooling of the heat exchanger can cause it to crack. This process could be accelerated if the heat exchanger is exposed to water and rust begins to set in. A crack in the heat exchanger means that the wall between the combustion gases and your breathing air has a flaw in it. This flaw now allows the harmful gases into the air that will be circulated all over the home.
The second problem involves the venting system, or chimney. If the chimney is improperly sized, either too large or too small, it cannot create an adequate draft to remove the gases from the home. Also if the chimney becomes obstructed by debris, or if ice builds up, it will become clogged and therefore not vent properly.
If you have carbon monoxide and smoke detectors installed in your home, you should be warned long before there is any permanent damage done to your family.
