When choosing a good gas refrigerator, it is important to consider how much space is available, the amount of freezer-to-refrigerator room needed, as well as looking at energy efficiency and price. Because gas refrigerators need to remain level to cool effectively, make sure that the location on which it is placed, such as in an RV, doesn't vary more than 3 to 6 degrees to the sides or back to front.
Gas-powered refrigerators tend to be smaller than their electricity-powered cousins, so those who want to go this route need to be prepared to sacrifice space in favor of freedom from electricity. Gas refrigerators average about 15 cubic feet, with the largest being around 19 cubic feet and the smallest at 3 1/2 cubic feet. One of the top gas refrigerators, the Norcold Inc. 323TR/L 3 Way Refrigerator, is only 4 cubic feet.
When looking for energy-efficient gas refrigerators, consider the EZ Freeze Model EZ-1850Q, S/D EZ Freeze Model EZ-1050W and Sunpentown Double Door Refrigerators. The first EZ Freeze model has one of the largest sizes at 19 cubic feet and is energy efficient, consuming only 1/3 gallon of propane per day. The 10 cubic foot EZ Freeze model uses only 1/4 gallon of propane. Those on a budget need to seek out a smaller gas refrigerator as they are generally more expensive than electric refrigerators. As of 2015, a 15 cubic foot gas refrigerator can cost upwards of a few thousand dollars.
