What Is the Difference Between Propane and Natural Gas?

Propane and natural gas are common fuels used in our daily lives. Understanding the difference between these two gasses is critical to choosing the right fuel for your needs. Below, we will discuss the differences between propane and natural gas. More on that later; first, let’s define natural gas and propane.

Natural gas is a non-renewable hydrocarbon that is nontoxic, flammable, and colorless. Methane is its primary component and typically constitutes 70-90% of its composition.

Besides methane, natural gas has other components, like ethane, butane, and propane (but in smaller portions). Its availability, clean burning properties, and wide range of applications make natural gas a great contributor to global energy consumption.

On the other hand, propane is a versatile hydrocarbon gas characterized by its colorless and nontoxic properties. The main propane source is natural gas processing, generated as a byproduct of the extraction and refining process.

Here are the differences between propane and natural gas:

  • Energy Content: Propane exhibits a higher energy content per unit than natural gas. This implies that a given volume of propane has more energy, making it an energy-dense fuel. Consequently, propane generates a higher heat output when burned, making it suitable for applications requiring high energy output. Examples of such applications involve powering industrial processes that need significant heat production or heating large areas. 
  • Storage and Transportation: Propane is often stored and transported in specialized tanks or cylinders. It is stored or transported in a compressed liquid state. Propane can be kept in smaller containers and transported conveniently because of its high energy density. On the other hand, natural gas is typically transported as a gaseous fuel through pipelines. It needs a vast network of pipelines to supply it to homes, industries, and businesses. 
  • Combustion Characteristics: Propane and natural gas exhibit different combustion characteristics. Propane undergoes combustion at higher temperatures and more efficiently than natural gas. This allows for a complete and cleaner combustion process. The high combustion temperature of propane gas makes it an excellent option for projects that demand accurate temperature control, like industrial furnaces. 

Natural gas is also a clean-burning fuel but can produce slightly higher emissions than propane because of the composition of the gas mixture. Thankfully, the advancements in combustion technology and emission control systems have lowered the environmental impact of natural gas. 

  • Safety Considerations: Propane and natural gas are combustible fuels that need careful handling and compliance with safety protocols. But there are some differences in their behavior in case of a gas leak. Propane, being heavier than air, tends to settle in low areas during a leak. This increases the chances of gas accumulating in confined basements, posing a significant risk if undetected. Natural gas, being light, disperses easily into the atmosphere during a leak, decreasing the risk of concentration in certain areas.

Both gasses are odorized with different additives that impart a strong smell to help in detecting leaks.

  • Applications: Propane has wide applications in residential settings for heating, cooking, and water heating. It’s also handy for outdoor applications, like grilling, camping, and commercial and industrial sectors. Natural gas is mostly used for cooking,  electricity generation, and residential and commercial heating. It also serves as a fuel source for industrial processes, including manufacturing facilities. 
  • Cost: The price of these gasses is subject to several factors that can cause price variations. Geographical location, for example, plays an essential role as access to natural gas infrastructure can affect the affordability of natural gas—those connected to the natural gas grid benefit from its widespread availability and lower distribution costs.

Propane, used in areas with limited access to natural gas infrastructure, might involve higher delivery and storage costs due to the demand for specialized tanks and distribution infrastructure. It must be noted that market conditions and supply and demand dynamics also affect the cost of both fuels.

Knowing the differences between propane and natural gas allows you to make wise decisions when choosing a fuel source that aligns with your needs.

Propane is a clean fuel source for homes, but the risk of fires, health issues, and property damage comes with it. Understanding these potential dangers is essential for taking preventive steps and responding swiftly during a leak. 

  • Fire and Explosion: As mentioned earlier, propane is an extremely combustible gas. It presents a significant fire risk when it leaks and builds up in a confined space. Even a tiny ignition source, like a spark, can trigger a catastrophic incident such as an explosion. The explosive nature of propane underscores the importance of quickly addressing leaks and ensuring adequate ventilation to deter the accumulation of gas concentrations.
  • Asphyxiation: Since propane is a colorless and odorless gas, manufacturers add an odorant to make it easily detectable. If the odorant goes undetected or you experience difficulty perceiving smells, the danger of asphyxiation increases. Inhaling high amounts of propane gas can disperse oxygen in the air, causing light headaches, suffocation and respiratory distress. A significant propane leak can trigger vomiting, coma, and death under extreme conditions.  
  • Health Effects: Exposure to propane gas has detrimental effects on health. Inhaling propane may irritate your respiratory system, causing coughs, shortness of breath, and chest tightness, among other symptoms. Extended exposure to high propane levels can trigger headaches, nausea, dizziness, and loss of consciousness. The severity of symptoms differs based on the duration of exposure. 
  • Property Damage: Apart from the immediate safety hazards, a propane gas leak can severely damage your property. Its explosive nature means that even a small ignition source can trigger fires that can easily engulf structures and possessions. It would help if you prioritized safety measures to prevent such incidents from taking place in the first place.

Conduct regular maintenance and inspection of propane appliances to address leaks. Also, proper ventilation in spaces where propane gas is stored is essential to deter gas accumulation.

How Do You Detect a Propane Gas Leak? 

While propane is an efficient fuel source, it can be life-threatening if mishandled. As such, detecting a propane gas leak will help ensure safety in any space where propane is used or stored. Here’s how to detect a propane gas leak:

  • Propane Gas Detectors: Set up gas detectors near propane appliances, including kitchens, utility rooms, and so on. Gas detectors are outfitted with sensors that can alert you to hazardous levels of propane gas in the air. The detector will sound an alarm when it detects a propane leak. Be sure to test your gas detectors regularly to ensure they function as expected. 
  • Smell: Propane has a unique odor resembling rotten eggs or a sulphuric scent. An odorant is added to propane to make it detectable by smell during a leak. If you notice an unusual smell in your immediate environment, it may suggest a propane gas leak. In such cases, acting promptly by vacating the place and seeking help from your propane supplier is important. 
  • Hissing Sound: A hissing sound coming from the pipes, valves, or attachments to the propane appliances indicates that there’s a gas leak. If you notice a hissing sound, immediately evacuate the area and contact emergency services or your gas supplier for help. 
  • Visual Clues: Examine the signs of a propane gas leak, including dying vegetation near gas lines. Plants rely on oxygen to survive. However, a propane gas leak supersedes this need by displacing oxygen in the air, leading to plant death or discoloration. Ice buildup on propane appliances is another sign of a gas leak. 
  • Test with Soapy Water: Use a soapy water solution to determine leaks in propane connections. Apply the soapy water to the connections, valves, and hoses of propane equipment and tanks. If bubbles develop, it signals a gas leak, so you should take immediate action to prevent explosions or fire risks.  

It’s important to prioritize safety during a propane gas leak. This involves turning off gas supply valves, ventilating the area, contacting emergency services, and evacuating the premises. Avoid addressing gas leaks yourself; let a certified technician touch it professionally.

Also, only re-enter the building once experts have deemed it safe. Consider preventive measures like educating family members about the appropriate actions during a propane gas leak. 

How Do Carbon Monoxide Detector Work?

You cannot taste or smell it, and in excess, it can kill instantly. Carbon monoxide is generated when combustion processes are incomplete. It can seep from mishandled heating systems at dangerous levels.

Common sources of carbon monoxide include faulty furnaces and portable generators. Carbon monoxide poisoning claims the lives of many people every year.

Luckily, carbon monoxide detectors are explicitly designed to address such concerns. These devices gauge the concentration of carbon monoxide in the air and sound an alarm if the concentration exceeds a hazardous threshold.

For example, if carbon monoxide is identified at 70 parts per million (ppm), in a few hours, the detector will activate an alarm to warn you of the potential threat.

Hazardous concentrations exceeding 400 ppm will follow suit within a few minutes. In any case, the detectors should offer an adequate warning, granting those nearby enough time to vacate before symptoms like loss of consciousness and nausea. Safety standards are in place to ensure these units sound their alarms when necessary.

Carbon monoxide detectors have different variations, each using a unique method to measure carbon monoxide levels. But one would ask how these gadgets precisely identify an unseen threat.

The most common type of carbon monoxide detector uses electrochemical sensors consisting of electrodes immersed in an electrically conductive solution (electrolyte). These sensors initiate a chemical reaction when carbon monoxide penetrates the gas-permeable compartment enclosing them.

As such, the electrical current flowing through the electrically conductive solution surges. The magnitude of this increase in current notifies the detector of the level of carbon monoxide molecules present.

Metal oxide sensors have a similar working mechanism to electrochemical sensors. Still, they depend on circuitry rather than a chemical solution. The material’s electrical resistance is reduced as carbon monoxide contacts a sensor’s chip.

The extent of the material’s resistance decrease is directly related to the carbon monoxide concentration in the surrounding air. By gauging the changes in resistance, the sensor can identify the gas level present.

With numerous technologies available, having a functional carbon monoxide detector minimizes the threat of carbon monoxide poisoning. It is advisable to install these devices per the manufacturer’s guidelines, usually in a central location outside each bedroom and on every floor of the premises. Equally important is to understand the local laws, codes, or standards, as they may have additional requirements for installing carbon monoxide detectors.

All sensors have a specified lifespan, which varies depending on the manufacturer. Carbon monoxide detectors that comply with the newest standards will indicate when they have reached maximum use and need replacement.2

Note: Taking proactive measures can help deter carbon monoxide production. This includes avoiding running car engines in enclosed spaces like garages. Similarly, you should operate portable generators outdoors and maintain a safe distance from your home’s entry points.


Carbon monoxide detectors are a must-have piece of equipment in your home or business, as they’ll alert you to dangerous carbon monoxide concentrations in the air. But…

Will Carbon Monoxide Detector Detect Propane Gas Leak?

Carbon monoxide detectors are only designed to detect carbon monoxide levels, a byproduct of incomplete combustion. Propane gas has its own characteristics and detection requirements.

The best way to detect a propane gas leak is by installing a separate propane gas detector to sound a siren and voice alarm when propane gas concentration approaches dangerous levels in the surrounding environment.
