Many people heat their homes in the fall and winter using a central furnace. While they are common in many homes, they are often fairly complex machines that the average homeowner knows little about. They require electricity, a combustible fuel source like natural gas, and hot air. In order to heat your entire home, that boiler needs to get really hot. In the 1960s and 1970s, there were roughly four furnace explosions per year on average. Thankfully, modern technological advancements have brought that number down to only about 0.3 per year. Regular furnace repair and maintenance can help keep the risks low.
Even with the dramatic reduction in furnace-related accidents, there are still occasional news stories on the catastrophic and often tragic results that can arise from faulty boilers. In late …show more content…
Being aware of the potential is also a big part of the solution.

Because of this denser molecular makeup, propane sits at the bottom of the room and does not emanate as much odor as natural gas. Had an open flame, electric spark, or even mono-filament light bulb come into contact with the gas, it would have combusted and set the whole place ablaze. Thankfully, a bit of precaution and a quick furnace repair negated that nightmare
