LPG and natural gas are similar in how they are used, however, LPG produces a much greater heat due to its higher calorific value. LPG is the same gas used in barbecues but it’s also used in space heaters, water heating systems, cookers and other applications.
LPG (Liquid Petroleum Gas) is generic name give to mixtures of hydrocarbons. LPG is mainly propane and butane stored in a liquid state. Natural gas is a hydrocarbon composed largely of methane.
Because LPG is stored in liquid form and is heavier than air, it tends to collect in low points. It is more difficult to disperse than natural gas, so more prone to catch fire or explode if a leak occurs.
Natural gas is lighter than air so disperses more easily if there is a leak.
