These appliances are popular for their efficiency and ability to provide instant heat, making them a preferred choice for cooking and heating. Using natural gas can be more cost-effective compared to electricity in many regions. Additionally, natural gas appliances often produce fewer greenhouse gas emissions than their electric counterparts, especially when the electricity is generated from fossil fuels. Proper installation and maintenance are essential for safety and optimal performance.
