How Does An Instant Water Heater Work?

Instant water heaters have a microprocessor built into them which controls the functioning of the heater. Microprocessors have introduced automation into the heaters which require minimal input and handling from the user. Microprocessors have sensors which determine the temperature and control the flow of water. Instant geyser water heaters operate on either instant electric geyser or gas.

Components 

• Microprocessor – It controls the overall functioning of the heater.
• Flow Sensor – Flow sensor is used to detect water flow in the heater which signals the microprocessor about the presence of water in the unit.
• Burner – Burner is used for supplying heat to the heat exchanger.
• Gas Inlet – Gas inlet is the point of entry of the gas into the burner.
• Fan – Fan is used to keep the burner ignited until the operation is completed.
• Heat Exchanger – The section in which the water is heated and then transported to tap.

Working of an instant water heater 

• The output tap or faucet is opened, and the cold water enters the heater through the inlet valve.
• This triggers the flow sensor present on the microprocessor, and the sensor starts administering the water flow.
• The computer automatically starts up the heating unit which heats the water.
• The water is circulated through the heat exchanger.
• The heat exchanger heats the water to a predetermined temperature.
• The hot water flows through the output valve.
• The heater continues to operate until the output faucet is closed and shuts down after the flow sensor detects an inactive water flow
