What Exactly Are Natural Gas and LPG?
Let’s get to know our two main players. While both are fossil fuels and both are used for heating, they have distinct characteristics.
Natural Gas: The Connected Option
Natural gas is a fossil fuel composed primarily of methane. It’s the most widely used heating fuel in many parts of the world, especially in areas with established underground pipeline networks.
How it works: Natural gas is delivered directly to homes through a network of underground pipes, similar to how water or electricity is supplied.
Availability: If your home is connected to a natural gas pipeline, you have access to this fuel. It’s common in urban and suburban areas.
Storage: No on-site storage is needed, as it’s supplied continuously.
LPG (Propane): The Versatile Alternative
LPG, or Liquefied Petroleum Gas, largely consists of propane and butane. It’s a portable fuel that is stored on-site in tanks.
How it works: LPG is delivered as a liquid under pressure and turns into a gas when you need it for your heater.
Availability: LPG is available virtually anywhere. If your home isn’t connected to a natural gas line, LPG is likely your best gaseous fuel option.
Storage: You’ll need a storage tank on your property to hold the LPG supply. These can be rented or purchased.

As a general rule, expect ongoing maintenance costs to be similar for both types of systems, with LPG potentially having an added cost for tank rental or a slightly more involved yearly inspection.
Safety First: What You Need to Know
Safety is paramount when it comes to any home heating system. Both natural gas and LPG are combustible fuels, so proper installation and maintenance are key.
Natural Gas Safety
Detection: Install carbon monoxide (CO) detectors on every level of your home, especially near sleeping areas. Natural gas itself is odorless, but utility companies add a distinct smell (like rotten eggs) to help detect leaks.
Leak Detection: If you smell rotten eggs, evacuate the house immediately and call your gas company or emergency services from a safe distance. Never use a phone, light switches, or appliances inside a gas-filled environment.
Professional Installation: Always use qualified professionals for any work involving natural gas lines or appliances.
Venting: Ensure your natural gas heater is properly vented to the outside to prevent the buildup of dangerous exhaust gases.
LPG Safety
Detection: Similar to natural gas, CO detectors are essential. LPG has a strong, distinctive odor added to make leaks noticeable.
Leak Detection: If you smell gas, turn off the main valve on the LPG tank if it’s safe to do so, open doors and windows to ventilate, and leave the area immediately. Call your LPG supplier or 911 from a safe location.
Tank Safety: LPG tanks must be installed by professionals, kept clear of flammable materials, and regularly inspected for damage or leaks.
Venting: Like natural gas heaters, LPG appliances require proper external venting.
For comprehensive safety information, you can consult resources from your local fire department or government safety agencies. For example, the U.S. Consumer Product Safety Commission (CPSC) provides valuable tips on home heating safety, including information on CO poisoning and safe fuel use.
