There are ten types of water coolers. While these water coolers would look very similar if they were sitting next to each other, they would also look very different. The Energy Star Cooler While shopping for water coolers for the workplace, I was surprised to learn that a typical unit uses much more energy than a full-size refrigerator. This is why I specified that the cooler model must have the Energy Star label so it will consume much less energy. The Environmental Protection Agency requires a product to meet strict guidelines to earn the Energy Star label, and the consumer can be assured that the unit will offer substantial savings on energy bills while providing maximum performance. In fact, EPA-qualified chillers produce savings of 40 to 50 percent compared to traditional units. The Top-Loading Water Cooler B&D's top-loading water coolers seemed like the best buy for my cramped little office. The height is 36 inches and the width is 16 inches, so it was easy to find a space for it. It has a capacity of 5 gallons and can cool water up to 38 degrees Fahrenheit. Hot water is also available up to 198 degrees. It comes with standard button controls and has a removable drip tray for easy cleaning. The 5 year manufacturer's warranty is very generous. Suddenly I became very popular among thirsty people. My colleagues stop constantly to refill their glasses and water bottles. The Bottleless Water Cooler Everyone in our busy office raved about the bottleless water coolers my boss had installed. It connects to the public water supply so we never run out and never have to replace the bottles. The water passes through five filters with...... half paper...... makes cleaning easier. Works with three and five gallon water bottles. The water always tastes much better than the public supply in our area. My husband even thought I bought a new brand of coffee because it tasted so good. I am very satisfied with it. Point-Of-Use Water Chillers We needed some Point-Of-Use (POU) water chillers to place in the office building. A cooler connected directly to the cold water line was specified to eliminate storing and changing large bottles. The high-quality filtered water had to be available 24 hours a day and had both hot and cold dispensers. The Sharpe refrigerator with 4-stage filtration advertised the ability to provide a busy office of 40+ people with continuous hot and cold water. The stainless steel bowl was very attractive and fit perfectly with the office decor. The 3 year warranty wasn't bad either.
