The washing machine consumes large amounts of energy and water, so make the wise decision and purchase the most energy efficient model for your lifestyle and space. When we speak about lifestyle, we consider how often we actually use these appliances and what we use them for. In this case, what garments we actually wash.

Now, when you want to use your washer and dryer often, it's best if you buy one with a stainless-steel tub. Those who wash less frequently will probably do fine with porcelain-coated steel or high-grade plastic. You can get a stacking washer-dryer unit if you don't have much space. Remember also that the size of your washer should match your dryer's capacity.

Think about what you will use them for. If your laundry includes a variety of fabrics and levels of dirtiness, choose a machine that offers specialty cycles such as delicate and extra soak, as well as one for a second rinse. For loads of different sizes, you want multiple water-level settings. Some machines can boost water temperature to sanitize a load. Other items to consider are automatic temperature regulators; a must in cold climates, they ensure that wash water comes in at a constant temperature for the setting.

There are two styles of washers: top-load, which is the most common, and front-load, which provides the greatest energy efficiency. Top-load washers allow the user to put in and retrieve laundry from the machine without bending over. These models have to be placed beside a dryer, however. Top-load models cost less, although it will prove to be less energy efficient in the long run.

Front-load washers are recommended for its energy efficiency, and indeed it has been steadily growing in popularity because of this feature. These models use only up to one-half of the water that is usually needed for a top-load machine. This also means less time and energy used for heating. And, because it spins faster, clothes come out needing less time in the dryer. Although they save on energy costs, front loaders cost more at purchase; some require a special detergent.

When selecting a dryer, the capacity you choose should go together with your washing machine's capacity. For example, if you have a washing machine with a 3.5 cubic foot capacity, you will need a 7-cubic-foot dryer. You can always buy a stacking model that can fit in a closet if space is a problem.

Dryers are powered by either gas or electricity. Gas models are typically more expensive to purchase, but it will prove to be more energy efficient and economical in the long run. Dryers must have at least one option for an automatic drying cycle, although the better models now have moisture sensors which allow to machine to shut down once the moisture level of the laundry drops below a certain point. Other options include a cool-down cycle that keeps garments from wrinkling, a damp-dry cycle that prepares clothes for ironing.
