It’s so easy and automatic that people just don’t think about it. Every year, when the weather turns cold, homeowners reach for household thermostats, flip a switch to turn on the heat and set the temperature to 68 or 70 degrees. Little thought is given to whether the furnace exhaust system – the chimney and connector pipe – is ready to provide safe, effective service.
Consumer confidence in the convenience and safety of today’s home heating systems is usually well-placed. The oil and gas heating industries have achieved impressive safety records. Nonetheless, over 200 people across the nation are known to die each year from carbon monoxide poisoning caused by problems in the venting – out of their homes – of toxic gases produced by their heating systems. This is according to statistics compiled by the U.S. Consumer Product Safety Commission. Other agencies estimate actual numbers at between 2,000 and 4,000.
In addition, around 10,000 cases of carbon monoxide-related “injuries” are diagnosed each year. Because the symptoms of prolonged, low-level carbon monoxide poisoning “mimic” the symptoms of common winter ailments (headaches, nausea, dizziness, fatigue, and even seasonal depression), many cases are not detected until permanent, subtle damage to the brain, heart and other organs and tissues has occurred. The difficulty of diagnosis also means the numbers of people affected may be even higher.
Fortunately, regular chimney system inspection and maintenance can prevent poisoning incidents like these.
What Carbon Monoxide Does to You
Too much carbon monoxide in your blood will kill you. Most of us know to try to avoid this. Less well known is the fact that low-level exposure to this gas also endangers your health.
One of the truths of our human bodies is that, given a choice between carbon monoxide and oxygen, the protein hemoglobin in our blood will always latch on to carbon monoxide and ignore the life-giving oxygen. Because of this natural chemical affinity, our bodies – in effect – replace oxygen with carbon monoxide in our bloodstream, causing greater or lesser levels of cell suffocation depending on the intensity and duration of exposure.
The side-effects that can result from this low-level exposure include permanent organ and brain damage. Infants and the elderly are more susceptible than healthy adults, as are those with anemia or heart disease.
The symptoms of low-level carbon monoxide poisoning are so easily mistaken for those of the common cold, flu or exhaustion, that proper diagnosis can be delayed. Because of this, be sure to see your physician about persistent, flu-like symptoms, chronic fatigue or generalized depression. If blood levels of carbon monoxide are found to be high, treatment is important.
Meanwhile, it makes good sense to put heating system inspection and maintenance on your annual get-ready-for winter list. Prevention is the best cure.
Causes of Heating System Problems
Why is poisoning from carbon monoxide on the rise? And why does it stem primarily from home heating systems that – at first glance – seem the same as those that have been used safely for years?
• Today’s houses are more air-tight. Homeowners are aware of the cost of heating drafty homes and have taken steps to seal up windows, doors and other areas of air infiltration. Consequently, there is less fresh air coming into a home and not as many pathways for stale or polluted air to leave it. And, when furnaces and boilers are starved of the oxygen needed to burn fuels completely, carbon monoxide is produced.
• Manufacturers have designed new, high-technology heating appliances whose greater efficiency helps us save money, conserve natural resources and decrease environmental pollution. However, the new breed of high-efficiency gas and oil furnaces – when vented in to existing chimney flues – often do not perform at an optimum level. The differences in performance create conditions that allow toxic gases to more easily enter home living spaces.
The above conditions point out a number of older, ongoing problems that still require detection and correction in order to prevent toxic gases from filtering into the house. These include damaged or deteriorating flue liners, soot build-up, debris clogging the passageway, and animal or bird nests obstructing chimney flues.
Caring for Your Chimneys & Flues
When gas and oil burn in vented heating systems – in order to produce household heat – the dangerous fumes that are by-products of combustion range from soot (particulate matter) to nitrogen dioxide (also toxic) to acidic water vapors formed when moisture condenses. None of these pollutants should be allowed to leak from the chimney into your living space.
In addition to carrying off toxic gases, chimneys also create the draft (flow of air) that provides the proper air and fuel mixture for efficient operation of the heating appliance – whether a furnace or boiler. Unfortunately, many chimneys in daily use in homes throughout the country either are improperly sized or have conditions that make them unable to perform their intended function.
