For some people, a fridge with a freezer is all that is needed for their frozen food. However, for households with more than 1 or 2 people, a larger freezer may be required. Stand alone freezers are available in 3 different types – upright, chest and compact. The type and size of freezer you purchase will affect your energy consumption.
Regardless of what type you purchase, ENERGY STAR freezers will be the most energy efficient. In order to qualify for the ENERGY STAR label a compact freezer must exceed the minimum regulated standard by 20%, where as standard sized freezers must surpass regulated standards by only 10%.
Upright freezers look similar to stand alone fridges in that they are tall and have a door that opens from the front.
Chest freezers are longer than they are tall and have a door that opens from the top. Chest freezers tend to be more energy efficient than upright freezers because doors on upright freezers allow more cold air to escape when opened.
Compact freezers are smaller versions of their larger counterparts. A compact freezer is any freezer than has an overall height less than 91.4 cm (36”) or a refrigerated volume less than 219.5 L (7.75 cu. Ft.). Compact freezers are available in both chest and upright models.
The newest freezers on the market use approximately 40% less energy than those found in today’s average household. Freezers manufactured in 2004 use less than half the electricity of those manufactured 15 years ago. Given that the average lifespan of a freezer is 21 years; your old freezer could be costing you more money in electricity than purchasing a newer, more energy efficient model.
