Signs Of Explosive Furnace Problems
Not all heating issues require an immediate service call, especially when the problem occurs on a weekend or at the end of the heating system. On the other hand, other types of issues can be an emergency due to their explosive nature. The following are some heater issues that can result in a fire or explosion in your home if they aren't addressed right away.
Electrical Issues
Any electrical issues with your furnace necessitate turning it off immediately. A short in the system can lead to burnt-out furnace components or worse, an electrical fire. Symptoms of an electrical problem include power surges and flickering lights elsewhere in the home each time the furnace powers on. The odor of burning metal can also indicate wiring issues that are leading to shorts and sparks. Do not use the furnace again until you have it inspected and repaired if you suspect electrical problems are occurring.
Sulfur Odors
The odor of sulfur or rotting eggs is a major cause for alarm if you have a gas or propane heater. These fuels are naturally odorless, but they are combined with a sulfur compound so that leaks can be noticed quickly. Turn off the furnace and leave your home if you smell these odors. An explosion or fire is a distinct possibility. When leaving the home, do not turn lights on or off and wait until you are outside to use your cell phone. Light switches and phones can produce minute sparks, which can ignite gas that is trapped inside your home. You will need to first call your gas company or fire department to address the leak. Then, a furnace tech will need to be brought in to find and repair the leak in your heater.
Bangs and Rumbles
Boiler and hot water systems, such as those used for some radiant floor heaters, may occasionally make small popping noises but you should never hear loud bangs or rumbles. If you do, then the water in the system may be overheating. Overheated water produces excess steam, which can lead to pressure issues. Pipes can burst or a boiler can explode. Leave your home immediately and call your heater service. Depending on your system, they may recommend that you bring in an emergency service if an explosion could be deadly.
Contact your furnace service right away if you experience any of these problems. Further, keep in mind that regular maintenance visits will decrease the chances of a severe furnace malfunction.
