A water cooler, also called water dispenser, is usually a machine that heats up or cools water and dispenses it with a special refrigeration unit located near the tap. It is usually located near the bathroom because of closer access to water pipes. A connection to the water cooler is also available from the water cooler to the sewage system. The water cooler has a water control valve which can be used to start the heating or cooling process. There is a thermostatically controlled shut off switch for the purpose of maintaining a constant temperature of the water.
