Collect information about working of Geyser and prepare a report
ikadub [295]
A geyser is actually a devise that coverts electrical energy into heat energy for heating up water. The heating element that is inside the geyser actually gets heated up and then in turn it heats the water in contact with it within the geyser. There is also a thermostat device within the geyser that cuts off the heating when the water temperature reaches the desired level. This helps in stopping of electrical energy loss. One inlet brings in cold water while another outlet gets rid of the hot water. When the temperature of the water falls below the desired level the heating is again started by the thermostat.
