Heating the water for washing clothes requires the most energy. Water use is a growing concern—and costs more—in many communities, reducing the water used in the clothes washer saves water, energy and money. Buying washers that use less water will help with energy and water conservation.
Traditional top-loading washers are the least expensive to buy, but most expensive to operate. They require more water and more electricity.
Front-loading models are usually the most expensive, and the most efficient to operate. Front-loading machines use a horizontal, tumble-axis basket to lift and drop clothing into the water instead of rubbing clothes around a central agitator. The tumble action reduces wear and tear on fabrics. These washing machines use less water, which also lowers heating costs.
Dryers
Washers and dryers consume large amounts of energy. In order to conserve energy consumption and save you money you should make sure your dryer is located in a heated space so it doesn’t have to work as hard. Another tip is to vent the dryer properly by using the straightest and shortest metal duct available. Flexible vinyl, aluminum and plastic ducts should be avoided because they can pose a fire hazard from sagging or clogging with lint. Ducts should be cleaned regularly (at least once a year). The outside dryer vent should close tightly and prevent the outside air from leaking inside. This vent should be checked periodically to make sure it is in working order. If air is leaking inside the house then energy and heat is getting wasted therefore costing you money.
After you have reviewed the areas of your house that are mentioned above and determined the repairs needed to make your home more energy efficient then you can test your audit and see if your precautions and repairs make a difference on your utility bills. If you see a significant difference you will know you have taken the proper measures and saved money in the process. If there is not a difference then you can decide whether or not to schedule a professional audit.
