Gas heating systems use natural gas or propane to generate heat for residential or commercial spaces. These systems typically consist of a furnace or boiler that heats air or water, which is then distributed throughout the building via ducts or pipes. They are known for their efficiency and ability to provide consistent warmth during colder months. There are various types of gas heating systems, including forced air systems, radiant heating, and combi boilers. Each type has its own advantages, such as quick heating or energy efficiency. Regular maintenance is essential to ensure safety and optimal performance of these systems.
