LP, or Liquid Propane, is a type of fuel gas commonly used in residential and commercial applications for heating, cooking, and water heating. It is stored under pressure in liquid form and converts to gas when released through a regulator. LP is often used in tankless water heaters, gas-fired boilers, and other plumbing-related appliances. Because LP is denser than air, it requires specific safety measures, including proper venting, leak detection, and adherence to local codes for safe installation and operation. Understanding LP’s properties, handling requirements, and safety precautions is critical for plumbers working with gas-fired systems.
