Water plays a major role in keeping your body healthy, and water coolers can give you safe and clean drinking water. A water cooler is a device that cools and dispenses water whenever you need it. Water coolers have become very popular these days, and you can find them in homes, offices, airports, malls, and many other places. They are also commonly called dispensers. Wall mounted water cooler: The wall mounted water cooler is the most common water cooler. Here, the cooler is connected to the water supply and electricity is used to run the refrigeration to cool the incoming water. The unused water can be disposed of in the building waste system. This kind of cooler usually has a container in the machine which holds the chilled water so that when you want some water, you just have to press the button which is on a spring loaded valve, and when it is released the water gets turned off. You do not have to wait for the water to come as it is already stored. Bottled water coolers: In the older version the water is used directly from the municipal water supply, but these days more emphasis is given on filtered water. The newer version has a free-standing design where bottled water is used. Here the bottle is placed spout down into the dispensing machine. These machines are of different sizes and vary from table units. The larger version can hold a bottle of up to 5 gallons. Depending on where it is needed, you can choose the most suitable size. For office use the larger one would be more suitable. The refrigeration function chills the water, but these units do not have a place to dump excess water, and only a small basin is there to catch minor spills. There are coolers which have a second dispenser to deliver heated water that can be used for tea, hot chocolate, instant coffee, etc. They can be quite handy at a lot of places, be it at home or office. Water coolers are quite popular especially with the kids, as they simply love to have an icy cold drink. You also do not need to keep water in the refrigerator as you can always have chilled water whenever you want it. It works great in an outside-enclosed area, like a shop or shed as anybody can just help themselves to a refreshing drink. Large water bottles are readily available and are more economical than buying other drinks, as you just have to refill them when needed. Some bottled water companies even offer filtered drinking water coolers to their clients. Advantages of filtered drinking water coolers over bottled water coolers: The good thing about having filtered water coolers in offices is that companies can cut their overhead costs without giving up the quality of the amenities provided to their employees. They can cut the hassles of having individual bottles, and eliminate their administrative and drinking water costs by just investing on water coolers which can dramatically improve the taste and quality of their office drinking water. This is also more convenient as you can avoid the hassles of having bottled water deliveries once or twice per month and the possibility of running out of water. With filtered water coolers you can always rely on having a supply of water available. So free yourself from the risk of any water infection with clean drinking water that is free of bacteria and algae, and get yourself a home water cooler! Enjoy a chilled glass of water on a hot day and a refreshing cup of tea in the morning to wake you up and prepare you for the day ahead.
