What is Propane?


To fully understand the difference between gas and propane is to know what propane is. While propane is a fossil fuel, it is not a natural gas. It also derives from the opposite source of green energy. So, exactly what is propane? Propane is a gas that is compressed and stored in liquid form. Not to be confused with gasoline, propane is produced from liquid components recovered during natural gas processing. These components include ethane, methane, propane, butane, and heavier hydrocarbons. For homeowners, if you use propane stoves for cooking, you’ll notice that unlike natural gas propane is sold in portable canisters. It can also be delivered to your home and stored in a  permanent storage tank.

What is Propane Made From?

  • Propane is made of a few different components. The makeup consists of ethane, methane, propane, and butane, and heavier hydrocarbons. While all of these components are made during natural gas processing, propane, and butane are also produced during crude oil refining.

Now that we have covered the basics of propane, we need to cover is propane the same as natural gas.

Is Propane the Same as Natural Gas?


While propane is a product of fossil fuels like natural gas, they are not the same. As a homeowner, knowing the answer to propane and natural gas the same can help you understand your energy bill more thoroughly! In terms of heating your home, you have a couple of different options. The most popular being electricity, natural gas, and liquid propane. When using propane gas for home, propane furnaces convert propane stored in a tank into a gas. This gas then moves warmth across a heat exchanger. When this element reaches a set point, a blower will then transfer the heat across the heat exchanger before it is distributed through the duct system.

What is the Difference of Propane and Natural Gas?

  • The main difference between the two is that propane is compressed into a liquid form and natural gas remains in its gaseous state. Propane is also typically delivered to the home by truck and stored in a permanent storage tank on the property. Natural gas, however, is delivered to the home via a pipeline.

So, what is natural gas used for in homes? Anything you need heat for! Think of hot water, cooking, or drying your clothes. All of these activities require natural gas or propane. This is why one of the biggest debates when buying appliances is whether gas or electricity is better. Unlike propane, natural gas is not stored in tanks. This means there are no natural gas tanks for home. Natural gas is produced from onshore and offshore natural gas oil wells and coal beds.

Natural Gas Vs Propane Gas – Which is Cheaper?


If your home has the option to support both natural gas and propane, cost is typically the most important concern. In order to find out the difference in propane and natural gas costs, we have to take a look at how they’re priced. Natural gas is priced per cubic foot, while propane is priced per gallon. It is difficult to directly compare prices due to continually fluctuating prices for both methods. But if you were to compare per unit, natural gas is cheaper than propane. Not only is it cheaper, but natural gas is also the preferred method of heating in the US.

Why is Natural Gas a Preferred Method of Heat?

  • Safety. Lighter than propane, natural gas dissipates more quickly than propane when released into the atmosphere. So, you could claim that natural gas is a little safer than propane which takes a little longer to dissipate.

Homeowners also look at which burns cleaner propane or natural gas. To find this out, we need to compare the BTU. This stands for British Thermal Units and is the standard measurement for heating efficiency. While you can have more energy-efficient appliances and a lower kWh rate, propane will still burn cleaner. This is another one of the major differences between propane and natural gas. Propane has a BTU of 2490 while natural gas’s BTU is around 1030. That’s almost double BTU for propane! This means that even if you’re paying more for propane per unit, the fuel will still burn cleaner. It will also heat your home more efficiently.

Is Propane Cheaper Than Gasoline?


Since propane is a liquid, it is often compared to gasoline. This often gets people asking, is propane cheaper than gasoline? The cost of gasoline is typically higher than propane. Propane is also a greener way to heat your home. But when used for the purpose of running your vehicle,  gasoline has a better average fuel economy. Some argue that propane’s lower cost per gallon allows for cheaper operating costs overall. But when using propane for a vehicle, you have to consider that any cost savings related to lower fuel pricing need to be evaluated with the cost of the vehicle conversion.

What are the 3 Con’s to Propane?

  • Propane produces fewer BTUs per gallon than oil heating.
  • Propane-burning equipment often costs more to purchase than heating oil-based systems.
  • Propane is combustible in the air, so precautions are needed to operate the equipment safely.

You should also think twice about switching to propane if your house runs on natural gas. Switching from one fuel source to another may require the mass purchasing of new appliances. You would have to invest in a new furnace, stove, grill, and other appliances that need heat. In some cases making expensive infrastructure upgrades is also necessary. Even if natural gas does turn out to be cheaper for your home, this investment can take years to recoup.
