Basically a suburban neighbourhood today has a grid that fuels the neighbourhood. You don't see the spaghetti piping of natural gas. Propane would be the same thing. The fuel tank would be off-site somewhere else. You wouldn't see it. There could be a network right under the homes to fuel everything that you want done in your house, including your hot water tank, furnace, fireplace, stove, dryer—even your lights.
