When you are trying to heat your home, which is better: natural gas or liquid propane? Liquid propane is a byproduct of natural gas. A generator that uses propane will boil the liquid to produce a gas that powers the generator. A generator that runs on natural gas does not need to boil its fuel, so it can work faster.
So who wins the fight when it comes to propane vs. gas generators? It depends on what you are looking for in a generator. Liquid propane generators tend to run quieter and the fuel never deteriorates or “expires.” Propane generally runs cleaner and the generators are cheaper to run than natural gas. Natural gas generators have lower maintenance costs and the gas itself is cheaper than propane (usually).
