What is a common use for LP gas in residential settings?

LP gas, or liquefied petroleum gas, is widely utilized in residential settings primarily for heating water. This application is advantageous due to LP gas's high energy content and efficiency compared to other fuel sources. Systems like gas water heaters efficiently heat water quickly, providing hot water for various household needs such as bathing, cooking, and cleaning.

While generating electricity, fertilizing crops, and cooling air are important functions in other contexts, they do not represent the predominant residential applications of LP gas. Generating electricity with LP gas typically involves large-scale operations rather than common residential use, and fertilization primarily relies on different compounds and methods. Similarly, cooling air is predominantly addressed through electric or other refrigerant-based systems rather than LP gas. Hence, the role of LP gas in heating water stands out as the most common and practical use in residential environments.
