Recently, front-loading washing machines have increasingly been coming onto the American market. Many people don't realize that front-loaders were in fact the original kind of washing machine, and it's top-loaders that came later. People in other countries will wonder what I'm talking about, because front-loaders have always been the most popular washers all over the world... except in the United States. snip
Water usage
Front loading washers use substantially less water than top-loading washers with an equivalent load size. For the same size load,
a top-loading washer uses about three times as much water as a front-loading washer. If you pay a water bill, the savings in cost of water can be substantial.
Detergent usage
Front loading washers require less detergent than top loading washers. A front-loader generally uses half as much detergent for the same size load, or perhaps even less. Indeed, too much detergent is more of a concern with front-loaders, because if the detergent causes too much suds, the suds will inhibit proper cleaning. So, a front-loading washer creates an immediate cost savings in detergent.
Energy usage
Front loading washers use substantially less energy. Because they use less water to wash a load, that means that they use less *hot* water to wash a load, which means they use less energy to heat water.
Cost of ownership
Between lower energy usage, lower water usage, and lower detergent usage, a front-loading washing machine is substantially cheaper to own than a top-loading washing machine. Indeed, a front-loader is so much cheaper to own, the savings (versus cost of ownership of a top-loader) will pay for the average front-loader within a few years.
