However, this information does not indicate whether one has selected the most efficient appliance. The most efficient appliance will have certain features that should guide the purchaser to selecting the most efficient model with those features. An example is clothes washers that are top loading vertical axis machines are not as efficient as clothes washers that are front loaders with a horizontal axis - both in energy and water use. Top loading machines, when used, should be selected according to the number of energy saving features that are offered in temperature settings, rinse cycles, and load sizes. The top freezer models outperform the side by side models and partial automatic or manual defrost models are the most efficient.
Many dishwashers offer special features that improve energy efficiency.
Booster heaters and no-heat drying are two helpful features. It is also important to know how much water is required by the different models and select those that can accomplish the cleaning with the least amount of water.
