While choosing a fuel for your home, consider its safety, cost, efficiency, and environmental impact when making your decision. For each of the aforementioned concerns, you’ll find everything you need to know about the benefits and drawbacks of natural gas and propane.
Safety
Both fuels are extremely combustible and should be handled with extreme caution. However, because of the infrastructure (and bureaucratic red tape) associated with natural gas pipes, leaks can be difficult to detect and repair. This is because, before taking action, utility firms and the public utility commission must agree on how to fund repairs or upgrades.
In San Bruno, Calif., for example, a natural gas pipe controlled by Pacific Gas and Electric (PG&E) exploded in 2010, killing eight people. The gas pipe was found to be damaged after an inquiry, and PG&E had previously been ignorant of the damage.
Although propane tanks have the potential to explode, this is a much less common scenario. Because propane tanks aren’t connected to a large network of gas lines, the impact is minimal.
Furthermore, while some natural gas suppliers add a sulfur fragrance to make it easier to notice a leak, natural gas leaks can be difficult to detect because the fuel is odorless in its natural state.
Propane is considered a safer heating fuel due to the severity of a mishap, however rare it may be.
Environment
Despite the fact that natural gas is a greenhouse gas, it produces half as much emissions as coal. Even yet, it has a higher toxicity than propane, which is neither hazardous nor harmful to the environment. If propane were to leak into the earth, it would have no effect on the water or soil in the area.
Nonetheless, both are still considered environmentally beneficial fuels. However, we give propane a minor advantage as a green fuel in this round.
Cost and Efficiency
The exact cost of propane vs. natural gas for your home is determined by a variety of factors, including whether or not your home is equipped for the fuels. However, for the purposes of this comparison, we’ll look at the cost of propane and natural gas in terms of BTUs and gallons.
The average cost of natural gas was $6.23 per 1,000 cubic feet, or nearly one million BTUs, at the time this article was written. Propane costs $2.41 a gallon on average in the United States. Natural gas contains approximately 11.20 litres of propane per million BTUs. That implies you’ll spend $6.23 for natural gas and $26.99 for propane for the same amount of fuel.
The more efficient the gasoline, the less you’ll consume, which affects the total cost. Furthermore, propane is the more efficient fuel in general.
Propane has 2,516 BTUs per cubic foot, while natural gas has 1,030 BTUs per cubic foot. Propane has more than double the energy content of natural gas.
Natural gas has a lower cost per gallon, but you’ll require more of it to heat the same appliances. Naturally, if you receive two times the heat from propane, you’ll need less of it.
Is it cheaper to use propane or natural gas to heat your home?
Cost. If you pay $15.00 per 1,000 cubic feet for natural gas, you’ll get roughly one million BTUs, which is little more than 11.20 gallons of propane. Using this example, if propane costs $2.50 per gallon, natural gas is the less expensive option.
What are the drawbacks of propane use?
The most significant disadvantage of a propane heating system is the need to maintain the tank or not. If you own the tank, you’re responsible for doing regular inspections and repairing any leaks or corrosion. It’s possible that you’ll have to replace the tank at some point.
Is propane a safer alternative to natural gas?
When it comes to deciding between natural gas and propane two clean-burning home energy sources that offer good value for your money there’s a lot of information and misinformation out there.
While aggressive marketing portrays natural gas as the plainly superior alternative, the reality is far more convoluted in fact, propane has significant advantages over natural gas that may tip the scale in its favor, depending on your requirements.
Here are five compelling reasons to consider (or keep with) propane for your Pennsylvania house rather than natural gas:
- Propane distribution is safer because it can be compressed easily for safe transit and is handled by highly skilled specialists who use equipment and methods that are strictly regulated by federal, state, and local authorities. Natural gas, on the other hand, is difficult to compress, necessitating pipeline delivery. You can’t use natural gas if there are no pipelines near your home; if there are pipelines near your home, you risk a possibly disastrous pipeline failure.
- Propane is more adaptable to utilize – in most circumstances, a propane line can enter your home wherever you want it to, as long as a tank is close (while there are some requirements for distance from the home for a propane tank, they are not overly restrictive). With a natural gas line, this may not be the case.
- Propane provides more energy than natural gas because it has double the quantity of useful energy per cubic foot – 2,490 BTUs versus 1,030 BTUs.
- Propane burns cleaner While both fuels are considered “clean,” natural gas is a fossil fuel that emits methane when burned, whereas propane combustion emits virtually no greenhouse gas.
- Propane is also a safer fuel than natural gas since it has a significantly smaller flammability range (minimum and maximum burn temperatures) than natural gas; propane will not ignite when mixed with air unless the ignition source reaches 920 degrees F.

Propane vs natural gas: which is worse for the environment?
When it comes to deciding between propane and natural gas, there is no clear-cut answer, as there is with many things in life. Both gases have their own set of benefits and drawbacks. Consider the following:
Natural gas is marginally safer than propane in the event of a leak. This is due to the fact that natural gas is lighter and hence dissipates faster into the atmosphere. Despite this, both gases are regarded as relatively harmless.
Efficiency
Propane is more efficient than natural gas because it produces more British Thermal Units (BTUs). This indicates that propane burns a smaller amount in an hour than natural gas.
Cost
Compared to propane, natural gas has a lower annual operational cost. Propane appliances are typically considered when natural gas is unavailable or obtaining natural gas to the home is prohibitively expensive. Hybrid propane and natural gas systems with an electric heat pump are also becoming more popular as a result of their efficiency and low operating costs.
Environmental Impact
Propane and natural gas are both relatively safe for the environment. Despite the fact that natural gas is a greenhouse gas, it burns cleanly and hence has a lower carbon footprint. Propane is an environmentally friendly fuel both before and after burning, meaning it has no negative environmental impact.
How long can 500 gallons of propane keep you warm?
The 500-gallon propane tank is the most frequent of all the residential propane tank sizes. When the cold weather arrives, you should at least know how long a 500-gallon gas tank will keep a house warm.
A 500-gallon propane tank can last anywhere from one month to fourteen months and four days. Check the chart and graph for different sizes of homes further down for accurate times.
During the winter, the average US household uses roughly 750 gallons of propane. That means the average US household will require two 500-gallon propane tank fills per winter (500-gallon tank holds a maximum of 400 gallons of propane; the 80 percent safety rule).
We’ll take a deeper look at a 500-gallon tank’s lifespan. This will allow us to more precisely determine how long 500 gallons of propane will last in homes varying in size from 500 to 4,000 square feet.
To determine how long a 500-gallon propane tank will last in your home, we must consider the following factors:
- Your home’s size. Larger dwellings demand more heating, and a 500-gallon propane tank will run out sooner than a smaller tank.
- criteria for heating (location). Houses in the north of the United States demand more BTU heating than houses in the south. For instance, in Texas, a 500-gallon propane tank will last longer than in Chicago.
- What is the severity of the winter? We will burn more propane in hard winters than in mild winters. According to the data for average US home winter use from 2010 to 2016, the 2013-2014 winter was the hardest, with an average usage of 830 gallons of propane compared to 750 gallons on a typical winter.
- Your propane-powered heating units’ energy efficiency. For example, high-efficiency propane furnaces with an AFUE rating of greater than 90 will use less propane to produce the same amount of heat than furnaces with an AFUE rating of less than 70. A 500-gallon propane tank will last longer as a result.
Why is propane so dangerous?
Because propane is widely used in both households and businesses, the chances of being exposed to harmful levels of the gas are high. Propane is an asphyxiant, meaning it can cause suffocating at extremely high doses. High-concentration exposure might potentially result in cardiac arrest, unconsciousness, or seizures. Frostbite can be caused by prolonged skin contact. Propane exposure at lower amounts can harm the central nervous system, lungs, and eyes, among other organs.
Is propane safe to use as a house heating fuel?
A well-functioning propane heating system can help you save money on electricity while also lowering your carbon footprint. Propane heat can actually cut greenhouse gas emissions by up to 68 percent. Furthermore, in addition to providing consistent, high-quality heat, propane is a great option for use with zone heating.
Is it possible to change from natural gas to propane?
- Despite the fact that propane and natural gas are both fossil fuels that burn similarly, you must convert your equipment when switching.
- Most, but not all, natural gas appliances can be converted to propane. The main issue is that natural gas is kept at a lower pressure, and some appliances, even with changes, can’t withstand the higher pressure of propane.
- When transferring from one to the other, you must switch out the valves and switches to appropriately manage the flow because they have different densities and amounts of energy.
- When switching from natural gas to propane, it’s crucial to consult a professional because the work is extremely technical and can be harmful if the person executing the work doesn’t have the necessary skills.
What are some of the advantages of propane?
Propane Has Six Advantages That Every Homeowner Should Know
- Produced in the United States. The fact that 80-90 percent of propane used in the United States is produced on domestic land is one of the elements that contributes to its cost-effectiveness and widespread use.
What is the average lifespan of a propane tank?
Grills, water heaters, and fireplaces all use small, portable propane tanks, often known as DOT tanks. They can weigh anywhere from 20 to 100 pounds. Its lifespan is determined by the size of your grill and how frequently you use your heater or fireplace.
A medium-sized grill on high heat will use about two pounds of fuel per meal as a rule of thumb. On a medium grill, a 20lb propane tank will give 18-20 hours of cooking time if you follow this rule. In as little as 10 hours, a larger barbecue can burn through 20 pounds of propane.
