Which gas is primarily used in residential heating systems?

Natural gas is the predominant choice for residential heating systems due to its availability, cost-effectiveness, and efficiency. It is supplied through a vast infrastructure of pipelines, making it accessible to a large number of households. Natural gas appliances are also designed to operate efficiently, producing a consistent heat output that meets the demands of most residential heating applications.

Compared to propane and butane, which are also used in some heating applications but typically in less urbanized areas or where natural gas lines are not installed, natural gas tends to be more plentiful and less expensive. Wood pellets, while a viable alternative for eco-friendly heating in some regions, are not as commonly utilized for conventional residential heating systems as natural gas, which remains the standard choice for a typical household heating solution. This widespread use and the established infrastructure make natural gas the leading option in this context.
