F.A.Q's and Answers
- What is the difference between a natural gas and LP model?
If your home uses "city gas" (Natural gas that is piped underground into the home through a supplied meter which is regulated and read by the utility company) You will use the natural gas model.
If your home has a large storage tank outside that it periodically refilled by a technician who transfers the gas from a delivery truck, you have LP gas. You will need an LP gas model.
Definition
Natural Gas
Natural Gas consists primarily of methane. It is found with fossil fuels, in coal beds, as methane clathrates, and is created by methanogenic organisms in marshes, bogs, and landfills. It is an important fuel source.
Natural gas is often referred to as simply gas, especially when compared to other energy sources such as electricity. Before natural gas can be used as a fuel, it must undergo extensive processing to remove almost all materials other than methane. Natural gas is abundant in North America and Northern Europe.
Liquid Petroleum Gas (LP - Liquefied Petroleum Gas) (Also called Propane, LPG, GPL, LP Gas)
Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butane, and the more common, mixes including both propane (60%) and butane (40%), depending on the season. In winter more propane, in summer more butane. Propylene and butylenes are usually also present in a small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. The international standard is EN 589.
LPG is synthesized by refining petroleum or 'wet' natural gas, and is usually derived from fossil fuel sources, being manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground.
