Freezers make it convenient to cook and freeze batches of meals or stock up on bulk frozen products in the grocery store. However, the price and amount of electricity to power the freezer might be a concern for budgetary and environmental explanations. Consumers can take action by comparing the energy usage of different freezer models before making a purchase.
Upright freezers generally use more electricity than chest freezers. This is because hot air rises; if a chest freezer is opened, the cold air remains low and inside the appliance, whereas with an upright, the cold air is replaced by room-temperature atmosphere. A new 17-cubic foot upright freezer with auto defrost uses an average of 684 kilowatt hours of electricity per year, explains Efficiency Vermont. A manual defrosting freezer uses just 480 kilowatt hours, which will be approximately 22 percent less energy.
A new chest freezer with manual defrost and 18 cubic feet of distance (1 cubic foot of distance more than the upright freezer in section 1) absorbs 432 kilowatt hours of electricity every year, or 10 percent less electricity than the smaller upright model. To learn the annual cost of running the freezer, multiply its kilowatt hours by the utility firm’s rate per kilowatt hour. Each appliance should get an energy guide label with its kilowatt-hour usage. For the ideal energy efficiency, consumers can select an Energy Star-rated freezer.
