Understanding the cost comparison between propane and natural gas helps homeowners make an informed decision. The table below highlights the differences in costs:

Heat SourceMonthly Running CostAverage Fuel Price
Natural Gas Furnace$30 – $60$1.40 – $2.10 per therm
Propane Furnace$90 – $200$2.00 – $2.50 per gallon

Propane Vs. Natural Gas Cost Comparison

Comparing cost factors beyond just fuel prices is essential for a comprehensive understanding.

FactorPropaneNatural Gas
Average Fuel Price$2.00 – $2.50 per gallon$1.40 – $2.10 per therm
AvailabilityStored in tanks, good for remote areasRequires piped network, limited to areas with infrastructure
Energy Content2,516 BTUs per cubic foot1,030 BTUs per cubic foot
EfficiencyHigh efficiencymay require more fuel due to lower energy content
Environmental ImpactReleases fewer pollutantsCleaner than oil or coal but more toxic than propane
SafetyHeavier, poses explosion risk if leaksLighter, dissipates quickly, reduced explosion risk
ConvenienceRequires storage and regular refillsContinuous supply, no need for refilling

Natural Gas Furnace

A natural gas furnace offers several benefits but also has some downsides.

ProsCons
– Less expensive than other fossil fuels– Higher upfront costs
– Burns cleaner than other fossil fuels– Emits harmful carbon monoxide
– Heats quickly and efficiently– May need extra space for ductwork
– Consistent fuel supply

Propane Furnace

Propane furnaces are suitable for off-grid homes and perform well in cold conditions, but they come at a higher cost.

ProsCons
– Ideal for off-grid living– More expensive than natural gas
– Multi-purpose usage– Requires storage tank and regular deliveries
– Performs well in colder climates– Propane-burning equipment is more expensive

Natural Gas Vs. Propane Cost Factors

The cost of heating with natural gas or propane is influenced by several factors, such as:

  • Efficiency – Propane typically has a higher energy content.
  • Availability – Natural gas requires piped infrastructure while propane is stored in tanks.
  • Environmental Impact – Propane releases fewer pollutants.
  • Safety – Propane is heavier and poses a risk if it leaks while natural gas is lighter and dissipates quickly.
  • Convenience – Natural gas offers a continuous supply, whereas propane requires regular refills.

FAQs About Propane Vs. Natural Gas

What Is Liquid Propane Vs. Natural Gas?

Liquid propane is stored in tanks and is used where a natural gas supply is not available. Natural gas, mainly methane, is supplied through pipelines.

Can You Buy Natural Gas Tanks?

No, natural gas is typically not available in tank form. It must be supplied through a piped network.

What Type Of Gas Is Best For Heating?

This depends on several factors, including location, availability, and specific heating needs. Natural gas is usually cheaper and more convenient, but propane is ideal for off-grid living and has higher energy content.

Getting Estimates From A Gas Or Propane Furnace Installer

When considering installation, getting estimates from professionals is essential. Here is what to consider:
