Which type of gas is commonly used for heating in residential settings?

Natural gas is the most commonly used gas for heating in residential settings due to its widespread availability, cost-effectiveness, and efficiency. It is delivered through pipelines directly to homes, making it convenient and reliable for homeowners. Natural gas has a high heat content, which translates to increased efficiency when used in furnaces, water heaters, and other heating appliances.

While propane and butane are also used for heating, especially in areas where natural gas is not available, they typically require storage tanks and are less prevalent in urban locations where piped natural gas infrastructure exists. Methane, although a primary component of natural gas, is rarely referenced separately in a residential context as it is largely regarded as the main component of the natural gas supplied for heating. Thus, when considering residential heating options, natural gas stands out as the primary choice.
