Natural gas is the primary gas used in residential heating systems due to its availability, efficiency, and safety features. It is delivered through an extensive network of pipelines, making it accessible to a large number of homes and businesses. Natural gas is favored because it burns cleanly, producing fewer pollutants compared to other fuels, which aligns with environmental concerns and regulations.

Additionally, natural gas appliances are generally less expensive to operate than those using alternative fuels, contributing to lower overall heating costs for homeowners. Its combustion produces significantly less carbon dioxide and other greenhouse gases compared to oil or coal, further enhancing its appeal as a heating option.

Alternative options, while viable, do not match the widespread use and benefits of natural gas in residential settings. Propane, although commonly used in rural areas where natural gas may not be available, lacks the same level of infrastructure support. Butane is typically used for portable applications rather than in fixed heating systems, while coal gas is largely outdated and has been replaced by cleaner fuel options.
