Gas heating is a method of using natural gas or propane to generate heat for residential or commercial spaces. This system typically involves a furnace or boiler that burns gas to produce warm air or hot water, which is then distributed throughout the building via ducts or pipes. Gas heating is popular due to its efficiency and ability to provide consistent warmth. In addition to furnaces, gas heating can also include gas fireplaces and space heaters, which offer localized heating solutions. Many homeowners prefer gas heating because it often results in lower energy bills compared to electric heating systems, making it a cost-effective choice for maintaining comfortable indoor temperatures.
