Freezer are used for freezing and prolonging the length of your food. There are two different types, these are upright and chest freezers. The maximum interior storage space tells you how much food can be stored in each appliance. If you like to have an organised freezer than you need to look at the number of compartments and drawers it has, or if it is a chest freezer how many storage baskets it has. If you are interested in saving electricity then you need to find out the energy consumption, which is measured in kw/year, and the energy efficiency grade. This is graded on a scale of A to G, where A is the best. The star freezer rating of the appliance is very important because this indicates how long food can be kept in the freezer, the more stars the better. Other features available are frost free, fast freeze facility, reversible door, high temperature warning light, a defrost spout that makes water collection easy when defrosting, adjustable thermostat for optimum efficiency, ice cube tray and manual defrost.
