Em ElectroMate Hot And Cold Water Dispenser.

Electromate hot and cold water dispensers are designed to provide both hot and cold water on demand. Water dispensers are useful in homes, offices, and public places for easy access to drinking water. They typically use between 0.3 and 1.2 kWh of energy per day for cold water and around 2.8 kWh for both hot and cold water. When a lever or button is pressed, water is dispensed through a spout. Inside, a thermally insulated tank with a heater keeps the water hot, and when the handle is pressed, cool tap water flows in, displacing the hot water out of the spout.
