Are You Using LPG or Natural Gas?

The last time you bought a new gas appliance- grill, dryer or range for example, you were likely asked what type of gas you used in your home.  Liquefied petroleum gas (LPG) or natural gas are both used to power those and other household appliances,but they have different properties and will be used differently in an appliance.

Liquefied petroleum gas (LPG),  is a product of crude oil distillation. It contains mostly propane, or C3H8. Propane has the nice property that, when you compress it, it condenses into a liquid. This means that it is much easier to store in a tank than natural gas, which does not easily compress.

Natural gas is just that — natural. If you sink a well in the right spot, natural gas flows out of the ground. It is mostly methane, or CH4.

Howstuffworks.com offers further explanation:

You can see the difference between natural gas and LPG most easily when you buy a gas stove. Normally, you are supplied with two sets of jets, one set for natural gas and one set for LPG. You install one jet in each burner. The jet is simply a little screw-in cap with a hole drilled into it. The difference is that the hole in the jet for natural gas is bigger — about twice as big — as the hole in the jet for LPG.

The reason for this difference is because LPG contains much more energy than natural gas. A cubic foot of natural gas contains something like 1,000 BTU (British Thermal Units) of energy. A cubic foot of propane contains perhaps 2,500 BTU. You can see that if you take a gas appliance set up for natural gas and then run it on LPG, the appliance is going to run more than twice as hot. In the case of a water heater , it is apparently hot enough to start a fire.

So, the seemingly simple question of what type of gas fuels your home, can be an important piece of fire safety information for protecting you and your family.

Newly Expanded GE Café Series of Appliances

The newest additions to the GE Café series include two counter-depth refrigerators, and a new electric range.

Refrigerators:

The counter-depth styling allows the appliances to blend seamlessly with the surrounding cabinetry, achieving a built-in look without the added expense of a built-in model.
The new counter-depth 25-cubic-foot side-by-side refrigerator is available with ClimateKeeper2™ technology, featuring a dual-evaporator system to create two zones of air circulation that help foods stay fresh. Because air is no longer circulated between the fresh-food and freezer compartments, the freezer’s cold, dry air won’t prematurely dry out foods, and odors won’t transfer between the compartments. Suggested retail price for this refrigerator is $3,249.

For home chefs who prefer the convenience of keeping produce and meats at eye level, GE will launch the 21-cubic-foot GE Café counter-depth bottom freezer with French doors. Now available with an internal water dispenser. Suggested retail price is $2,899.

Offered as a free-standing, slide-in range, the new GE Café Electric Range offers consumers without a gas line the ability to have a restaurant-inspired range. The range includes a fifth center burner and cast-iron griddle on the cooktop, a PreciseAir™ convection oven, and a double-oven configuration with a drawer that heats up to 450 degrees for added cooking flexibility. An optional stainless steel backsplash is available (model JXS80SS). The GE Café electric free-standing range (model CS980SNSS) will be available November 2008 with an estimated retail price of $2799.
