Liquid Propane and Natural Gas: Comparing Appliances

liquid-propane-and-natural-gas-comparing-appliances

When choosing new kitchen appliances, homeowners in New Hampshire and Vermont often face an important decision: liquid propane (LP) or natural gas. Both fuels are popular across New England due to their efficiency, reliability, and cost-effectiveness, but they differ in key ways that can influence your appliance selection and long-term satisfaction.

Understanding Liquid Propane vs. Natural Gas

Liquid propane is a byproduct of natural gas processing and crude oil refining. It is stored as a liquid in pressurized tanks, typically located on your property. This makes LP an excellent option for rural or off-grid homes where natural gas lines are unavailable.

Natural gas, on the other hand, is delivered directly to your home through underground pipelines. It is lighter than air and does not require on-site storage, making it a convenient option for homes connected to municipal gas systems.

Key Differences in Kitchen Appliances

From a performance standpoint, both fuels can power a wide range of kitchen appliances, including stoves, ovens, and cooktops. However, there are subtle but important differences:

  • Heat Output: Liquid propane generally burns hotter than natural gas. This means LP-powered stoves can heat up faster and reach higher temperatures, which can be appealing for home cooks who value precision and speed.
  • Efficiency: Because propane has a higher energy content per cubic foot, LP appliances often operate more efficiently. However, natural gas appliances tend to have lower fuel costs in areas where gas lines are available.
  • Availability: In many rural parts of Vermont and New Hampshire, propane is often the only viable option. In more urban or suburban areas, natural gas may already be connected to your home.
  • Installation Requirements: Natural gas appliances require a fixed pipeline connection, while propane appliances rely on a tank and regulator system. This can impact installation costs and logistics.

Can You Convert Between Liquid Propane and Natural Gas?

Yes, many kitchen appliances can be converted from one fuel type to the other, but the process is not as simple as flipping a switch. Conversion typically involves:

  • Replacing or adjusting burner orifices to regulate fuel flow
  • Modifying or replacing the appliance regulator
  • Ensuring proper air-to-fuel mixture for safe combustion

It is critical that a technician licensed for gas line work is involved in the conversion. Manufacturers often provide conversion kits specifically designed for their appliances which technicians can install.

Important Considerations Before Converting 

Before deciding to convert an appliance, homeowners should consider:

  • Safety: Improper conversion can lead to gas leaks, incomplete combustion, or carbon monoxide risks.
  • Warranty: Some manufacturers void warranties if conversions are not performed correctly.
  • Professional Installation: It is strongly recommended to hire a licensed technician to handle any conversion work.

Making the Right Choice for Your Home

For homeowners in New Hampshire and Vermont, the decision between liquid propane and natural gas often comes down to availability and lifestyle preferences. If your home already has access to natural gas, it may be the most cost-effective and convenient choice. However, propane offers flexibility and high performance, especially in areas without gas infrastructure.
