A natural gas heater is a device that uses natural gas as a fuel source to generate heat for residential or commercial spaces. It operates by burning natural gas to produce warmth, which is then distributed through ducts or radiators. These heaters are popular for their efficiency and ability to provide consistent heating during colder months. Natural gas heaters come in various types, including furnaces, boilers, and space heaters. They are often preferred over electric heaters due to lower operating costs and faster heating capabilities. Regular maintenance is essential to ensure safety and optimal performance.
