Natural gas is superior. Propane generates 10 to 20 percent fewer BTUs than natural gas. This means, for instance, that propane will take longer to boil a pot of water. And it more readily blackens the bottoms of pots and pans because it does not burn as cleanly as natural gas. Propane has its place. It fuels nearly all outdoor gas grills. If you live in a country home that is not connected to a natural gas pipeline - and you do not like the alternative of cooking on an electric range, then propane is the answer. You will need an outside propane tank and a range that can be converted to use propane.
