If you want to buy meat in bulk, stock up on sale items or have storage space for extra ice cream, a deep freezer represents a valuable asset. When deciding whether to purchase one, it is wise to consider the electricity use of a chest freezer. Models earning the government's Energy Star label exceed requirements for energy efficiency.
0.14 to 0.2 cubic metres
The smallest deep freezers offer 0.14 to 0.2 cubic metres (5 to 7.2 cubic feet) of capacity. Energy Star models use 230 to 282 kilowatt hours of electricity each year, which translates to an annual operating cost of £15 to £19.
0.25 to 0.36 cubic metres
You'll need 294 to 362 kilowatt hours of electricity to operate a chest freezer with 0.25 to 0.36 cubic metres (8.8 to 12.8 cubic feet) of capacity. Expect to spend £20 to £25 to run these models for a 12-month period.
0.37 to 0.42 cubic metres
Energy-Star models with 0.37 to 0.42 cubic metres (13 to 14.9 cubic feet) have an annual energy use of 326 to 397 kilowatt hours. Running one of these models adds £19 to £27 to your electricity bill each year.
0.56 to 0.7 cubic metres
The largest deep freezers hold 0.56 to 0.7 cubic metres (19.7 to 24.9 cubic feet) of frozen items. They consume 434 to 568 kilowatt hours of electricity every 12 months. Expect to spend £29 to £39 to operate one.
