Every year, gas explosions morph American homes into flames. “Even though gas furnaces are engineered with several safety features, many of these conflagrations could be prevented with an annual preventative heater tune up,” states a heating contractor of St. Louis City (StL).
A cracked heat exchanger is not the type of heating repair that’s obvious to the average StL City homeowner. This is the primary reason a yearly check up on the furnace can be lifesaving. Because the combustive nature of a cracked heat exchanger, St. Louis City residents should turn off any furnace with cracks running along the heat exchanger and schedule heating maintenance immediately,” forewarns a heating contractor licensed in St. Louis.
For added protection and precautionary measures, place a carbon monoxide detector on every level of your St. Louis home,” advises Robert Hoffmann, founder of the Hoffmann Brothers heating contractor St. Louis.
How the heat exchanger of your gas furnace operates?
The heat exchanger is responsible for keeping fumes away from the gas flue and ventilation system. Housed in a clam-shaped, metal chamber a heat exchanger collects gas combustion from the burner, transferring heat into its metal walls. Once cooled, the heat exchanger ultimately exports the combustive effects out of the home.
How does a heat exchanger become cracked?
If there is a venting problem, a cracked heat exchanger transpires on both new and old furnaces. The natural reaction between combustion gas and metal oftentimes promotes rusting, particularly in an aging furnace. When this corrosion sets in a furnace, replacement is the inevitable remedy to the problem. For the most part a cracked heat exchanger is common on aging heating systems and furnaces over the age of 12.
On a newer furnace, corrosion is susceptible if the exhaust is improperly vented. Even if the cracks are minuscule, these fissures have the ability to gape to the point where the heat exchanger expands when the furnace is at the most intense heating cycle. Hence, a cracked heat exchanger will ultimately leak combustion gas out of the furnace cabinet if not repaired or replaced.
