Gas appliances are devices that use natural gas or propane as a fuel source to perform various functions in homes and businesses. Common examples include gas stoves, gas ovens, water heaters, and furnaces. These appliances are popular for their efficiency and ability to provide instant heat or hot water. To operate safely, gas appliances require proper installation and regular maintenance. It's important to ensure that they are connected to a ventilation system to prevent the buildup of harmful gases like carbon monoxide. Regular checks by a qualified technician can help ensure that these appliances function safely and efficiently.
