Propane Vs. Natural Gas Furnaces

Propane vs. Natural Gas Furnaces: Which One Should You Choose?

Choosing between propane and natural gas furnaces is one of the most important choices homeowners must make when it comes to heating their homes. Both choices have benefits and drawbacks that affect everything from availability and environmental impact to cost and efficiency.

Choosing the appropriate fuel type is essential if you want to upgrade your heating system in order to preserve comfort and control energy costs. We’ll compare natural gas and propane furnaces in this thorough guide to help you decide which one best meets your needs.

Our specialty at BCRC Heating and Cooling is offering professional HVAC solutions, making sure homeowners select the most economical and effective heating systems. Before you make a choice, let’s examine all the information you require.

Comprehending Natural Gas and Propane

It’s important to comprehend what propane and natural gas are and how they function as heating fuels before delving into a comparison.

Propane: What Is It?

One kind of liquefied petroleum gas (LPG) that is extracted as a byproduct of processing natural gas and refining crude oil is propane. It is kept in pressurized tanks and, when released, transformed into a gas for use in water heaters, stoves, furnaces, and other appliances.

Important Propane Features:

stored in a tank as liquid and transformed into gas when needed.
offered in bulk tanks or refillable cylinders.
frequently utilized in places without natural gas pipelines.
It is more efficient than natural gas because it has a higher energy content per unit.

Natural Gas: What Is It?

Methane makes up the majority of natural gas, a fossil fuel. It is taken out of subterranean reserves and delivered straight to residences and commercial buildings via pipelines. Natural gas offers a steady fuel supply via a utility connection, in contrast to propane, which needs storage tanks.

Important Characteristics of Natural Gas:

supplied through subterranean pipelines, doing away with the requirement for storage.
extensively accessible in both urban and suburban settings.
less expensive per unit than propane.
reduces emissions by burning cleaner than other fossil fuels.

Now that we have a better understanding of both fuel types, let’s examine the key differences between natural gas and propane furnaces.

Energy efficiency: Which one better heats?

Energy efficiency is an important consideration in choosing the best heating option for your home. Furnaces are rated for efficiency using the Annual Fuel Utilization Efficiency (AFUE) rating, which tells you how much of the fuel is converted into usable heat.

Efficiency of Propane Furnaces

Modern propane furnaces are extremely efficient, with some models achieving up to 98% AFUE. This means that 98% of the propane that is burned is converted to heat and only 2% is wasted. Additionally, propane has more energy per cubic foot than natural gas, meaning it can generate more heat with less fuel usage.

Efficiency of Gas Furnace

Natural gas furnaces often have efficiency ratings ranging between 80% and 95% AFUE. Some high-efficiency models can reach 95%, but they still can’t match propane’s superior energy output per unit. But it is somewhat less efficient, due to the lower cost of natural gas and thus more economical.

The winner is : Propane

Propane furnaces take the lead if energy efficiency is your priority, due to their higher energy content per cubic foot and higher AFUE ratings.

Cost Comparison: Which Is Cheaper?

When it comes to propane vs. natural gas furnaces, cost is a big factor. We will look at three main cost categories: installation, fuel and maintenance.

Installation Cost

Propane Furnaces: Requires a storage tank to store propane fuel, which may result in additional installation costs between $500 and $3,000, depending on the size and setup.
Natural Gas Furnaces: Require connection to a municipal gas line and may require a one-time hookup fee of $1,500-$5,000 if no hookup currently exists.

Cost of Fuel

Propane: Costs between $2.50 and $4.00 per gallon, making it more expensive per unit than natural gas.
Natural Gas: $0.90 to $1.30 per therm, so much cheaper over time.

Maintenance Cost

Both natural gas and propane furnaces require regular inspections and maintenance as well. Propane furnaces, however, require additional checks of storage tanks and fuel lines, which makes their maintenance a little more expensive.

Natural Gas Winner

Propane furnaces tend to be more efficient, but natural gas furnaces are more cost-effective overall due to lower fuel costs and lower maintenance costs in general.

Environmental Impact: Greenest Option?

Environmentally conscious homeowners need to look at the environmental impact of their heating options when comparing propane vs. natural gas furnaces.

Effect of Propane on Environment

Has lower carbon emissions than natural gas.
Non-toxic and does not contaminate soil or water in case of leaks.
More energy-dense, requiring less fuel for the same heat output, leading to reduced emissions.

Natural Gas’s Environmental Impact

Still cleaner than oil or coal but releases methane, a potent greenhouse gas.
Pipeline leaks contribute to environmental damage.
Advances in renewable natural gas (RNG) are improving sustainability.

Winner: Propane

While both fuels are cleaner than traditional heating oil, propane has a smaller carbon footprint and poses fewer environmental risks.

Availability: Which Is More Convenient?

Your location plays a significant role in determining whether propane vs. natural gas furnaces are more accessible and convenient.

Propane Availability

Can be used anywhere, making it ideal for rural and off-grid areas.
Requires regular refills and storage space for tanks.

Natural Gas Availability

Requires access to a municipal gas line, making it more convenient for urban and suburban homeowners.
Provides a continuous supply without the need for fuel deliveries.

Winner: Natural Gas (For City Dwellers), Propane (For Rural Homes)

If you have access to a municipal gas pipeline, a natural gas furnace is the most convenient choice. However, for those living in remote areas, propane furnaces offer the best heating solution.

Safety Considerations

Safety is a crucial aspect when comparing propane vs. natural gas furnaces. Both fuels require proper handling, maintenance, and awareness of potential risks.

Propane Safety

Heavier than air, meaning leaks can settle in low-lying areas.
Contains an added odor for easy leak detection.
Requires regular inspections to prevent leaks and ensure safe operation.

Natural Gas Safety

Lighter than air, dispersing quickly in case of leaks.
Requires proper ventilation and carbon monoxide detectors to prevent risks.
Pipeline leaks can be hazardous if not properly maintained.

Winner: Tie

Both propane and natural gas furnaces require strict safety measures, including regular inspections, leak detection, and proper ventilation to prevent carbon monoxide buildup.

Which Is More Comfortable Heating Performance

Another important thing to consider when deciding between propane vs. natural gas furnaces is their heating performance and ability to provide consistent comfort in cold weather.

Propane Heating Efficiency

Burns hotter than natural gas for immediate and more intense heat.
Good for colder climates that require more heating power.

Natural Gas Heating Performance

Provides even heating but takes longer to reach high temperatures.
Better for milder climate areas where extreme cold is not a big concern.

The winner is : Propane

Propane furnaces are a better choice in colder areas as they are more efficient in extreme temperatures and provide more heat.

Lifespan and Durability: Which is more durable

Investing in a durable furnace is important to be most cost-effective in the long run. Propane and natural gas furnaces are both durable, but their lifespans are different.

How Long Does a Propane Furnace Last

Usually 15-20 years with proper maintenance.
Needs close monitoring of storage tanks and fuel lines to avoid corrosion or leakage.

Life Expectancy of a Natural Gas Furnace

Regular maintenance can last 15 to 25 years.
Less trouble with fuel storage and a little longer lifespan.

Natural Gas Winner

Both furnace types are very durable but natural gas furnaces may last longer because of fewer storage related issues.

The Bottom Line: Which Furnace Should You Pick?

Now that we’ve looked at propane vs. natural gas furnaces, here’s a quick summary:

Factoring	Propane Heater	Natural Gas Heating
Efficient	✅ More effective	Efficiency reduced slightly
Cost of Gasoline	Go on	✅ Cheaper
Installation	Storage tank required	✅ Utilizes pipeline (if available)
Upkeep	A bit higher	less
Environmental Consequences	✅ Burns cleaner	Methane production
Availability	Suitable for countryside	✅ Good for city apartments
