How much propane does the typical American home burn through for heating? According to the EIA's 2020 Residential Energy Consumption Survey, the average household consumes approximately 390 gallons of propane annually. This translates to about 35.7 million BTU per year, with each gallon of propane packing roughly 91,452 BTU of heating power.

However, that national average masks some dramatic regional differences.

Would you believe that a Wyoming homeowner might use nine times more propane than someone in Hawaii? It's true. Households in frigid Wyoming typically consume around 84.9 million BTU (928 gallons) annually, while homes in tropical Hawaii use a mere 9.4 million BTU (103 gallons).

Why such extreme variation? Climate plays the starring role, with home size as the supporting actor.

Just how dominant is heating in your propane budget? The National Renewable Energy Laboratory estimates that approximately 85% of all residential propane usage goes toward keeping you warm. That single statistic completely changes how you should think about managing your propane costs.

Beyond location, your home's size dramatically affects consumption. Industry data provides some practical guidelines based on square footage:

The relationship follows simple logic: larger homes in colder regions require more propane to maintain comfortable temperatures. Meanwhile, smaller, well-insulated houses in milder climates typically fall at the lower end of these ranges.

This significant variation across states highlights why your location matters enormously when estimating propane needs. While national averages provide a starting point, your regional climate might tell a completely different story.

Consumption for Water Heating

After keeping your home warm, what's the second-biggest propane guzzler in most households? That hot shower you enjoy every morning.

On average, a family using propane for water heating will use between 200 and 300 gallons annually. That breaks down to roughly 1.5 gallons per day, or about 15 to 25 gallons each month.

But here's where it gets personal: your household size dramatically shifts these numbers.

A two-person household might use just 10 to 15 gallons monthly, while a family of four could consume around 25 gallons in the same period. Add another person or two, and you're looking at 30+ gallons per month.

This follows a simple rule of thumb: expect about 5 gallons as baseline usage to keep the water heater running, plus an additional 5 gallons per person per month.

Technology matters, too. That tankless water heater you're considering? Its propane consumption varies significantly depending on flow rate, desired temperature increase, and usage patterns. For a family of four, a propane tankless system typically uses around 1.5 gallons daily.

Here's something puzzling: EIA data from 2020 indicates higher average consumption—about 35.7 million BTU annually, which translates to approximately 390 gallons. Why the discrepancy from the 200-300 gallon range? It likely reflects differences in survey methods or household configurations.

What drives higher water heating consumption? More people taking longer showers is the obvious answer. But did you know that raising your water heater's temperature by just 10 degrees can increase energy use by 3-5%?

While tankless systems promise efficiency gains, their actual propane appetite depends heavily on your household's specific hot water demands. In high-demand scenarios, they might actually match or even exceed efficient storage tank models—something the glossy brochures don't always emphasize.

Consumption for Cooking

You might assume that cooking three meals a day would burn through propane quickly. Surprisingly, it's actually one of the smaller slices of your propane pie.

The typical annual consumption for a propane stove ranges from just 35 to 60 gallons. Even households that channel their inner chef daily land toward the upper end of this modest range. On a monthly basis, expect to use between 3 and 5 gallons, depending on your cooking habits.

How can cooking use so little propane compared to heating applications?

The answer lies in two factors: intermittent usage and the remarkable efficiency of propane burners. A single gallon of propane can power a large burner on your stove for over five hours. This energy density, combined with the fact that most people don't cook continuously throughout the day, explains why cooking represents just a small portion of your overall propane budget.

EIA data categorizes cooking under "other residential propane uses," showing an average consumption of 81 million BTU per household annually. Since cooking represents just one component of this broader category, the industry estimate of 35-60 gallons yearly (approximately 3.2 to 5.5 million BTU) aligns reasonably with their findings.

Consumption for Clothes Drying

What about drying your clothes with propane? It's even more efficient than cooking.

The average propane dryer uses around 20 gallons annually, with monthly usage of approximately 1.5 gallons. That's remarkably little when you consider how many loads of laundry the typical household runs.

NREL data confirms this modest consumption, indicating that only about 1% of total residential propane use goes toward clothes drying.

Why so efficient? Propane dryers generate high heat quickly, reducing drying times compared to some alternatives. This places them firmly in the "minor contributor" category of your household's propane usage.

Think of it this way: your propane dryer might use less fuel in an entire year than your furnace uses during a single cold week in January.

Consumption for Other Appliances (Fireplaces, Generators)

Beyond the everyday workhorses of heating, cooking, and drying, propane powers some of your home's most beloved luxuries and critical backup systems.

Ever wondered how much fuel that cozy propane fireplace consumes while you're enjoying a movie night? Typically between 1 and 3 gallons per hour, depending on size and BTU rating. A fireplace rated at 50,000 BTU will use roughly one gallon every two hours while in operation.

Unlike your furnace, which runs predictably throughout winter, fireplace usage is highly personal. Some homeowners might use theirs daily during cold months, while others reserve it for special occasions. This makes estimating annual consumption particularly tricky.

What about that backup generator that saved you during the last power outage?

Propane generators typically consume between 2 and 4 gallons per hour, with consumption varying based on generator size and electrical load. A standard 22kW household generator might use around 2 gallons per hour at half capacity, increasing to 3.6 gallons per hour at full load. Smaller 8kW models generally consume between 2 and 3 gallons per hour.

Here's the kicker: a single extended power outage during a winter storm could consume more propane than all your cooking for the entire year. Yet, in areas with reliable electrical service, your generator might sit unused for months.

Propane calculators should incorporate the frequency and duration of use for these variable-use appliances rather than relying on typical annual figures. A fireplace used daily throughout winter will have dramatically different requirements than one lit only on special occasions.

When calculating propane needs for these occasional-use appliances, think in terms of hours of operation rather than annual totals.

Commercial Propane Consumption Metrics

Consumption for Space Heating

How do businesses use propane differently than homes? While the applications might be familiar, the scale changes dramatically.

According to EIA data from 2018, approximately 32% of all energy consumed by commercial buildings in the US goes toward space heating. This translates to a massive 2.2 quadrillion BTU from a total energy footprint of 6.8 quadrillion BTU.

Natural gas dominates the commercial heating market, but propane plays an essential role where natural gas infrastructure doesn't reach. Its portability makes it particularly valuable for businesses in rural or developing areas.

Different types of commercial buildings show surprisingly distinct heating patterns. Did you know that warehouses dedicate the largest portion (39%) of their energy use to heating, with a space heating intensity of 15.8 MBtu per square foot? Office buildings allocate about 30% of their energy to heating, with an intensity of 20.1 MBtu per square foot.

The entire US commercial sector consumed 188.65 trillion BTU of propane for heat content in 2023. But this figure encompasses all commercial propane applications, not just heating.

A commercial propane furnace typically uses between 1 and 2 gallons per hour when operating. The annual consumption? That's where things get complicated.

Why can't we give you a single "typical" consumption figure for commercial buildings? Because a small rural retail store has fundamentally different heating needs than a sprawling warehouse or a busy restaurant. The extreme diversity of commercial operations makes establishing a standard consumption rate nearly impossible.

Consumption for Water Heating

When it comes to commercial water heating, propane faces stiff competition. Natural gas leads the market at approximately 78% of the total, while electric systems come in second, with about 61% of commercial buildings nationwide using electric water heaters.

So, where does propane fit in? Primarily in regions without natural gas access. And consumption rates? They vary dramatically depending on the business type.

Consider the difference between a small office building with a single restroom versus a hotel with dozens of showers running throughout the day. Hotels, restaurants, and healthcare facilities—with their continuous hot water demands—naturally consume significantly more propane for water heating than retail stores or warehouses.

While residential data suggests a propane tankless water heater might use around 1.5 gallons daily for moderate demand, larger commercial operations can have exponentially higher requirements. A busy restaurant might use that much propane for hot water in a single hour of operation.

Consumption for Commercial Cooking

Did you know that food service buildings allocate a whopping 40% of their energy consumption to cooking? That's according to EIA data, highlighting just how energy-intensive commercial kitchens truly are.

While natural gas remains the most common cooking fuel, with 81% market share, propane offers compelling advantages for commercial kitchens, particularly in temperature precision and control.

A commercial propane cooktop typically consumes approximately 1 gallon per hour of use. Larger equipment like commercial ovens and fryers have higher BTU ratings and proportionally higher propane consumption.

What makes propane attractive for restaurants despite natural gas dominance? Performance characteristics—quick temperature response, even heating, and reliability—potentially resulting in lower operating costs compared to electric alternatives.

Commercial propane cooking equipment typically lasts eight years or more, and ENERGY STAR certified propane equipment delivers efficiency gains of 10% to 60% compared to standard models. For restaurants operating on tight margins, these efficiency improvements translate directly to the bottom line.

Costs Associated with Residential Propane Systems

Wonder what it actually costs to set up and maintain a propane system beyond just filling the tank?

Installing and maintaining propane systems involves a web of expenses that vary based on your specific setup. For a propane furnace, expect to pay approximately $2,000 to $5,000 for installation—a wide range that reflects differences in unit efficiency, size, and installation complexity.

Water heaters present their own cost spectrum. A standard tank-type propane water heater typically costs between $800 and $2,500 to install, while tankless models jump to $1,500 to over $4,000. Why the premium for tankless? Their more complex venting and plumbing requirements demand additional labor and materials.

Then there's the tank itself. Above-ground tanks generally run between $500 and $2,000, depending on size and site preparation needs. Thinking of going underground for aesthetic reasons? That'll cost you—typically $2,000 to $5,000 or higher—due to excavation requirements and additional safety measures.

What about the smaller appliances? Installing propane stoves or dryers tends to be more affordable, typically between $150 and $500 per appliance, though this can increase if new gas lines need to be installed.

Don't forget ongoing maintenance. Most residential propane systems benefit from annual servicing, which ranges from $100 to $300 yearly. Potential repair costs vary significantly based on equipment age and condition, much like any home system.

Historical Regional Price Ranges (Past 5-10 Years)

Ever noticed how gas prices vary between states? Propane follows the same pattern—but with even more dramatic regional differences.

As of March 17, 2025, the U.S. average residential propane price was $2.712 per gallon, according to EIA data. But this national average masks some eye-opening regional variations.

The East Coast typically faces higher prices, averaging $3.598 per gallon, with New England often experiencing the highest rates nationwide. Meanwhile, Midwestern residents enjoy substantially lower prices at $2.214 per gallon on average—a difference of nearly $1.40 per gallon for essentially the same product!

Gulf Coast residents pay around $2.984 per gallon, while the Rocky Mountain region averages $2.416 per gallon.

What's particularly interesting? These regional price differences have remained fairly consistent over time. When tracking weekly price data over the past year, we see that while prices move up and down with seasons, the relative relationship between regional markets holds steady.

Factors Influencing Price Variations

Why would identical propane molecules cost so much more in Maine than in Michigan? Several key factors drive these persistent price differences.

Supply and demand dynamics play the lead role—higher heating demand during winter inevitably pushes prices upward. Transportation costs follow closely behind. Since propane often travels by truck or rail, fuel prices and logistical challenges directly impact what you pay.

Refining and storage capacity creates another variable, especially during peak demand periods when available supply becomes constrained.

Seasonal fluctuations represent the most predictable pattern in propane pricing, with prices typically peaking during the coldest months when heating demand surges. This is why many savvy propane users fill their tanks during the summer months when prices typically hit their annual lows.

While this guide focuses on the US market, global energy conditions can sometimes create ripple effects that influence domestic propane pricing, particularly during supply disruptions or unusual market conditions.

Conclusion

Now that you've seen the real numbers behind propane usage, here's what matters most for your calculator results:

For home heating—the true giant in your propane budget—expect 400 to 1,300+ gallons annually, depending on your home's size and climate. Water heating adds another 200-390 gallons.

Cooking and clothes drying? They're surprisingly minor players at just 35-60 and 20 gallons, respectively. Those flashy propane fireplaces and standby generators vary wildly based on how often you actually use them.

Regional price differences aren't random—they reflect infrastructure realities that remain remarkably consistent year after year. Understanding these patterns helps you interpret calculator results for your specific location.

Remember that while calculators provide useful estimates, your actual consumption depends on your unique circumstances—from insulation quality to personal habits. But now you know which factors truly drive your propane needs.

Use these insights alongside your calculator results, and you'll make smarter decisions about your energy system and budget.
