What Is Propane And Natural Gas?
Propane and natural gas are used for heating, cooking, and generating electricity. They are both gases that are stored in tanks or pipelines and are distributed to homes and businesses.
Propane is a hydrocarbon gas stored as a liquid in pressurized tanks. It is commonly used as a fuel source for heating, cooking, and generating electricity. Propane is also used as a vehicle fuel and raw material in manufacturing chemicals.
On the other hand, natural gas is a mixture of gases, primarily methane, that is stored in underground reservoirs and transported to homes and businesses through pipelines. It is commonly used for heating, cooking, and generating electricity. Natural gas is also used as a fuel for vehicles and as a raw material in the chemical industry.
The Differences Between Natural Gas And Propane.
Propane and natural gas are both commonly used as fuel sources, but there are some key differences between the two:
Composition
Propane is a byproduct of petroleum and natural gas processing, while natural gas is primarily composed of methane.
Storage
Propane is stored as a liquid in pressurized tanks. In contrast, natural gas is stored underground reservoirs and transported through pipelines to homes and businesses.
Energy Content
Propane has a higher energy content per unit of volume than natural gas, which means that it is more efficient as a fuel source.
Cost
Natural gas is typically less expensive than propane due to its greater availability and lower production costs.
Usage
Propane is commonly used for heating, cooking, and generating electricity in homes and businesses, as well as for fueling vehicles and as a raw material in the chemical industry. Natural gas is also used for these purposes and to generate electricity in power plants.
Safety
Propane is highly flammable and explosive, which makes it a potential fire and explosion hazard. Natural gas is also flammable, but it is less explosive than propane.
Environmental Impact
Natural gas is considered a cleaner fuel source than propane, as it releases fewer emissions when burned. However, the production and transportation of natural gas can have significant environmental impacts, such as air and water pollution.
Are Natural Gas And Propane Interchangeable?
No, natural gas and propane are not interchangeable. Although they are both gases used as fuel sources, they have different chemical compositions and properties that make them unique.
Natural gas primarily consists of methane, while propane is a byproduct of natural gas processing or refining petroleum. Propane has a higher energy density than natural gas. It can be stored in tanks for later use, making it a popular fuel source for homes and businesses in rural areas or for use in recreational vehicles.
In addition, the appliances and equipment used for natural gas and propane are different and are not compatible with each other. This means that an appliance designed to use natural gas can only be converted to propane and vice versa by making significant changes to the appliance.
So while natural gas and propane are commonly used as fuel sources, they are not interchangeable and must be used with the appropriate equipment and appliances.
Is It Better To Have Natural Gas Or Propane?
Whether it is better to have natural gas or propane depends on various factors, including:
Availability
Natural gas is typically only available in certain regions with a natural gas pipeline network. Propane, on the other hand, can be delivered to homes and businesses by truck, making it more accessible in rural or remote areas.
Cost
The cost of natural gas and propane can vary greatly depending on location and availability. Natural gas is often less expensive than propane on a per-unit basis, but the cost of propane can be more stable.
Efficiency
Both natural gas and propane are highly efficient fuel sources. However, the efficiency of a particular appliance may vary depending on whether it is designed to use natural gas or propane.
Environmental impact
Natural gas is a fossil fuel that produces greenhouse gases when burned. Propane is also a fossil fuel, but it produces fewer greenhouse gases per unit of energy than natural gas.
Why Do People Use Propane Instead Of Natural Gas?
Propane and natural gas are both commonly used as fuels for heating and cooking. Still, people may choose propane over natural gas for several reasons.
Propane is a type of liquefied petroleum gas (LPG) stored in a tank and used as needed. In contrast, natural gas is typically supplied through pipelines. This means that propane can be used in areas without access to a natural gas pipeline, such as rural areas. Propane is also portable, so it can be used for outdoor cooking and heating, making it a popular choice for recreational vehicles and outdoor activities.
Also, propane burns hotter than natural gas so it may be more efficient for certain heating applications. However, propane can be more expensive than natural gas, especially if you have to have the tank refilled.
What Happens If You Use Propane Instead Of Natural Gas?
If you use propane instead of natural gas, it could cause damage to your appliance and affect its performance. Propane and natural gas are not interchangeable, and using one instead of the other could result in a gas leak or fire. Propane and natural gas have different characteristics, such as pressure, heating value, and composition. This means that appliances that use natural gas may not function properly with propane and vice versa.
In addition, appliances designed to use propane may not work optimally with natural gas, as the pressure and heating value of the two fuels is different. This can result in incomplete combustion, which can cause damage to the appliance, reduce its efficiency, and potentially create indoor air quality issues.
Therefore, always use the correct fuel for your appliance and consult a licensed professional if you need to convert your appliance from one fuel to the other.
Are Natural Gas And Propane Stoves The Same?
No, natural gas and propane stoves are not the same. While both types of stoves use gas as a fuel source, they are designed to work with different types of gas and have different combustion characteristics.
Natural gas stoves are designed to be connected directly to a natural gas line. They use natural gas as their fuel source. Propane stoves, on the other hand, typically use propane from a tank or cylinder and are not directly connected to a natural gas line.
Because of the differences in pressure and heating value between natural gas and propane, stoves designed for one fuel may need to be fixed with the other. For example, a stove designed for natural gas may need more heat when used with propane, and a stove designed for propane may produce too much heat when used with natural gas.

Why Is Propane Better Than Natural Gas?
Propane and natural gas are both popular fuel sources for heating and cooking. Still, each has its advantages and disadvantages. Here are some of the key factors that make propane a better choice in certain situations:
Portability
Propane is stored in tanks and can be easily transported, making it a good choice for homes not connected to a natural gas pipeline.
Energy Density
Propane has a higher energy density than natural gas, meaning that it contains more energy per unit of volume. This makes it a more efficient fuel source for heating and cooking.
Performance in Cold Weather
Propane is less likely to freeze than natural gas and continues to work efficiently even in very cold weather. This makes it a good choice for areas with harsh winters.
Remote Location
Propane can be delivered to remote locations that may not have access to natural gas pipelines, making it a good choice for rural or remote homes.

Natural Gas To Propane Conversion Calculator
To convert natural gas to propane, you can use the following calculator:
- Determine the BTU rating of your natural gas appliance.
- Multiply the BTU rating by 1.10 to get the equivalent propane BTU rating.
- Divide the propane BTU rating by the BTU rating of propane to determine the propane consumption rate in gallons per hour.
For example, if your natural gas appliance has a BTU rating of 50,000, the equivalent propane BTU rating would be 55,000 (50,000 x 1.10). If the propane has a BTU rating of 91,600, the propane consumption rate would be 0.6 gallons per hour (55,000 / 91,600).
Natural Gas Vs Propane Orifice
Natural gas and propane orifices are designed differently because they have different characteristics. Natural gas orifices have larger holes than propane orifices because natural gas has a lower heating value and pressure than propane. Propane orifices have smaller holes because propane has a higher heating value and pressure than natural gas. Therefore, using the correct orifice for your gas appliance is important to ensure safe and efficient operation.
How Is Propane Converted Into Natural Gas?
Propane is not converted into natural gas, as they are two different gases. Propane is a byproduct of natural gas processing and petroleum refining, while natural gas is primarily composed of methane and is extracted directly from underground gas deposits. However, propane can be liquefied and transported in tanks for use as a fuel source.
Changing Orifice From Natural Gas To Propane
To change an orifice from natural gas to propane, follow these steps:
- Turn off the gas supply to the appliance.
- Remove the burner assembly from the appliance.
- Locate the orifice on the burner assembly.
- Use a wrench or pliers to unscrew the orifice from the burner assembly.
