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.
