Is Your Boiler or Water Heater at Risk of an Explosion Due to BLEVE?

When it comes to your home's heating system, safety should always be a top priority. Your boiler or water heater may seem like simple appliances that keep your home warm and comfortable, but they can actually pose significant risks if they aren’t properly maintained.

One danger that many homeowners aren’t aware of is the risk of an explosion due to BLEVE.

What is a BLEVE?

BLEVE stands for "boiling liquid expanding vapor explosion." This type of explosion occurs when a pressurized vessel containing a liquid reaches a critical temperature, causing the liquid to rapidly boil and turn into steam. The resulting increase in pressure can cause the vessel to rupture and release a massive and dangerous amount of hot vapor. 

This type of explosion can be incredibly dangerous, causing serious injuries and even fatalities.

Why Are Boilers and Water Heaters at Risk of an Explosion Due to BLEVE?

Boilers and water heaters are commonly used in homes to provide heat and hot water. These appliances contain pressurized tanks that hold water or other fluids that are heated to high temperatures. If the pressure relief valve fails, the pressure inside may continue to increase until an explosion occurs.

Many homeowners may not be aware of the warning signs that their boiler or water heater is at risk of a BLEVE. Over time, the metal in these appliances can weaken and corrode which can increase the risk of a catastrophic explosion.

What Can You Do To Prevent a BLEVE?

Fortunately, there are steps you can take to reduce the risk of an explosion due to BLEVE in your home. The most important step is to have your boiler or water heater regularly serviced by a professional heating and plumbing company like First Service.

Regular Maintenance

Regular HVAC maintenance can help identify any potential issues with your heating system before they become a major problem. During a service appointment, your technician will inspect your heating system, clean any buildup, and check for signs of corrosion and other damage.

In addition to reducing the risk of a BLEVE explosion, regular HVAC maintenance of your system can improve its efficiency and extend its lifespan. A well-maintained heating system will not only keep your home safe but also help you save money on your energy bills while preventing costly repairs down the line.

Ensure That Your Heating System Is Properly Installed and Vented

One of the most important steps to prevent BLEVE is to ensure that your heating system is properly installed and vented. Improper installation or venting can lead to an accumulation of pressure or gas, increasing the risk of a dangerous explosion.

Keep Your Heating System Away From Flood

Make sure that your heating system isn’t installed in an area that is prone to flooding. Flooding can damage your heating system, leading to corrosion and weakening of the metal. 

In addition, if flood waters come into contact with your heating system, it can cause a rapid rise in temperature, increasing the risk of a BLEVE.

Educate Yourself and Your Family on the Dangers of BLEVE

Educate yourself and your family on the dangers of a BLEVE and what to do in case of an emergency. Make sure that everyone in your home knows where the gas and water shut-off valves are located and how to turn them off. If you suspect a BLEVE may be imminent, evacuate your home immediately and call 911.

BLEVE Warning Signs That You Need To Pay Attention To

In addition to regular maintenance, it's important to pay attention to warning signs that your heating system may be at risk for a BLEVE explosion. These include:

• Strange noises coming from your boiler or water heater
• Leaks around the pressure relief valve
• Water that is too hot or not hot enough
• A sudden decrease in water pressure
• Rust or other signs of corrosion in the appliance
