Natural gas is the fuel predominantly used in residential heating systems. It is supplied through a network of pipelines, making it a convenient and reliable energy source for heating homes. One of the main advantages of natural gas is its efficiency and cost-effectiveness compared to other types of gas. When burned, natural gas produces a significant amount of heat energy while emitting fewer pollutants than many other fossil fuels.

In residential applications, natural gas is favored for its availability and its ability to be used in a variety of appliances, including furnaces, water heaters, and stoves. Additionally, natural gas is generally more affordable for consumers due to its widespread production and distribution infrastructure.

While propane and butane are also used for heating, they are typically used in areas where natural gas is not available, or in specific applications such as outdoor grills or portable heaters. Methane, while it is the main component of natural gas, is not a separate fuel type used in residential systems; instead, it is primarily processed as natural gas. Thus, natural gas stands out as the predominant fuel for home heating.
