↑ Back to top

Upfront Costs

Propane Installation

• Tank lease (most common): $0 upfront, $50-75/year lease fee included in deliveries
• Tank purchase: $1,800-$4,000 (250-1,000 gallon tank, owned outright)
• Interior piping: $800-$1,500 (plumber installs gas lines to appliances)
• Total upfront (leased tank): $800-$1,500
• Total upfront (owned tank): $2,600-$5,500

Natural Gas Installation

• Pipeline hookup (if available within 100 ft): $2,000-$7,000
• Pipeline extension (if >100 ft away): $15-$30 per foot (often $10,000-$30,000+)
• Interior piping: $800-$1,500
• Total upfront (pipeline nearby): $2,800-$8,500
• Total upfront (pipeline 1 mile away): $40,000-$80,000+ (often cost-prohibitive)

Annual Operating Costs

Typical 2,500 sq ft Texas home (heating + hot water + cooking):

Propane

• Annual usage: 800-1,200 gallons
• Fuel cost at $2.80/gal: $2,240-$3,360
• Delivery fees: $50-$150 (6-10 deliveries)
• Tank lease (if applicable): $50-$75
• Total annual cost: $2,340-$3,585

Natural Gas

• Annual usage: ~1,100-1,600 therms (equivalent energy to 800-1,200 gal propane)
• Fuel cost at $1.50/therm: $1,650-$2,400
• Monthly service charge: $10-$20/month ($120-$240/year)
• Total annual cost: $1,770-$2,640

Total Cost of Ownership (TCO) — 10-Year Example

Scenario: Natural gas available 100 feet from home (low hookup cost)

• Propane TCO (10 years): $2,600 upfront + ($2,960 × 10) = $32,200
• Natural gas TCO (10 years): $4,500 upfront + ($2,200 × 10) = $26,500
• Natural gas saves $5,700 over 10 years

Scenario: Natural gas requires 1-mile pipeline extension

• Propane TCO (10 years): $32,200 (same as above)
• Natural gas TCO (10 years): $42,000 upfront + ($2,200 × 10) = $64,000
• Propane saves $31,800 over 10 years

Natural gas pipeline coverage in our service area:

• Granbury: Available in city limits and some subdivisions; rural areas generally not served
• Weatherford: Good coverage in city; spotty in surrounding Parker County
• Cleburne: Available in most of city limits
• Glen Rose, Stephenville, Peaster, Lipan, Mineral Wells: Limited or no natural gas service in rural areas
• Hood County (rural): <5% of rural properties have natural gas access
• Parker County (rural): <10% of rural properties have natural gas access

1. Available Anywhere

No pipeline required. If a delivery truck can reach your property, you can have propane. This makes it the default fuel choice for rural Texas.

2. Backup Power Capability

Propane generators are the gold standard for whole-home backup power. When winter storms knock out the grid (2021 freeze, 2022 ice storm), propane generators keep running. Natural gas generators exist but are less common and require existing gas hookup.

3. Provider Choice

Propane is a competitive market. You can switch providers anytime (if you own your tank). Natural gas = single utility provider with regulated monopoly pricing.

4. Energy Independence

Propane stored in your tank = fuel supply under your control. Natural gas = dependent on pipeline infrastructure. If utility shuts off service or pipeline fails, you're without heat. Propane users keep fuel on-site.

5. Higher Heat Output

Propane burns hotter than natural gas (2,500°F vs. 1,960°F). Faster cooking, faster water heating. Some chefs prefer propane for temperature control.

↑ Back to top

1. Lower Operating Cost (where available)

10-35% cheaper per BTU than propane (depending on market rates). Predictable pricing (regulated utility rates).

2. No Deliveries

Continuous supply via pipeline. Never run out or need to schedule refills.

3. No Tank on Your Property

Aesthetic advantage (no visible tank). No tank maintenance or inspections.

4. Fixed Monthly Billing

Budget billing available (spread costs over 12 months). Predictable payments.

When Propane Makes More Sense

Choose propane if:

• ✅ You're in a rural area with no natural gas access
• ✅ You need backup power (whole-home generator)
• ✅ Natural gas line extension would cost >$10,000
• ✅ You want provider choice and competitive pricing
• ✅ You're building on a property without utilities infrastructure yet

When Natural Gas Makes More Sense

Choose natural gas if:

• ✅ Natural gas is already available at your property (existing hookup or <$5,000 to connect)
• ✅ You don't need backup power (grid-dependent lifestyle)
• ✅ You prioritize lowest possible operating cost
• ✅ You prefer never thinking about fuel deliveries
• ✅ You're in an urban/suburban area with mature utility infrastructure

Some North Central Texas homeowners use BOTH:

Natural gas for daily use (heating, cooking, hot water)
+
Propane for backup power (whole-home generator)

How it works:

• Natural gas hookup for appliances (lower operating cost)
• 250–500 gallon propane tank dedicated to generator (runs during outages)
• Generator automatically switches on when grid power fails

Cost:

• Natural gas hookup: $2,000–$7,000
• Propane tank + generator + installation: $8,000–$15,000
• Total upfront: $10,000–$22,000

Best for: Suburban homeowners with natural gas access who also want storm/outage resilience.

Location: Rural Hood County (no natural gas lines within 2 miles)

Options:

1. Pay utility to extend natural gas line: $45,000+ (utility quoted $25/foot for 1.8 miles)
2. Install propane with owned 1,000-gallon tank: $5,500 upfront

Homeowner chose propane.

15-year TCO:

• Propane: $5,500 + ($3,500/year × 15) = $58,000
• Natural gas (if extended): $45,000 + ($2,200/year × 15) = $78,000

Propane saved $20,000 over 15 years + provided backup power capability for whole-home generator.

Use this formula to calculate your TCO:

Natural Gas TCO

Upfront Cost (hookup + piping) = $________
Annual Fuel Cost (therms × price/therm) = $________
Annual Service Charge ($10-20/month) = $________
Total Annual Cost = $________ (fuel + service)

10-Year TCO = Upfront + (Annual × 10) = $________

Propane TCO

Upfront Cost (tank + piping OR piping only if leasing) = $________
Annual Fuel Cost (gallons × price/gallon) = $________
Annual Delivery Fees ($10-25/delivery × deliveries/year) = $________
Annual Tank Lease (if leasing) = $________ (or $0 if owned)
Total Annual Cost = $________ (fuel + delivery + lease)

10-Year TCO = Upfront + (Annual × 10) = $________

Compare the 10-year TCO numbers. That's your real cost difference.

1. Can I convert natural gas appliances to propane (or vice versa)?

Yes, but it requires conversion kits and professional installation.

• Most modern furnaces, water heaters, and stoves CAN be converted
• Conversion kit: $50–$300 per appliance
• Labor: $100–$300 per appliance (must be done by licensed technician)
• Some appliances cannot be converted (check manufacturer specs)

Cheaper to buy the right appliance upfront than convert later.

2. Is propane safer than natural gas?

Both are safe when properly installed and maintained.

Propane advantages: Heavier than air (sinks to low spots, easier to detect), stored in your tank (no pipeline leaks from street to home), odorant added (smells like rotten eggs).

Natural gas advantages: Lighter than air (dissipates quickly if leaked), no tank corrosion risk.

Bottom line: Safety is equivalent. Both require carbon monoxide detectors, leak detection, and proper ventilation.

3. Does propane or natural gas produce more carbon emissions?

Propane produces slightly fewer carbon emissions per BTU than natural gas.

• Propane: ~12.68 lbs CO₂ per gallon
• Natural gas: ~13.06 lbs CO₂ per therm

But the difference is negligible (3% less for propane).

4. Can I heat my whole home with propane?

Yes. Propane furnaces, boilers, and space heaters work identically to natural gas models. Propane forced-air furnace: 90-98% AFUE efficiency (same as natural gas). Heating performance is identical to natural gas. The only difference is fuel delivery method (tank vs. pipeline).

5. What if natural gas becomes available in my area after I install propane?

You can switch, but it's expensive:

• Natural gas hookup: $2,000–$7,000
• Appliance conversions: $150–$600 each (or buy new appliances)
• Remove/abandon propane tank (if leased, we remove; if owned, you pay removal or leave in place)

Most homeowners who install propane stay with propane unless natural gas infrastructure arrives AND offers a compelling cost advantage (rare in rural areas).

6. Do propane prices fluctuate as much as natural gas prices?

Yes—both fuels fluctuate based on crude oil prices, supply/demand, and seasonal factors.

Propane: Prices peak in winter (high demand for heating), drop in spring/summer (low demand). Hedge: Pre-buy programs let you lock in pricing before winter.

Natural gas: Prices vary by region and utility regulations. Some utilities offer fixed-rate plans. Generally more stable than propane (regulated utility).

If price stability matters, natural gas has an edge—but pre-buy propane programs close the gap.

7. Can I run a generator on natural gas?

Yes, but with limitations:

Natural gas generators: Require existing natural gas hookup, lower power output per unit of fuel (compared to propane), can run indefinitely during outages (continuous fuel supply).

Propane generators: Work anywhere (no hookup required), higher power output per unit of fuel, limited by tank size (500-1,000 gal = 3-7 days of continuous runtime for whole-home generator).
