How does it work?

Certain components are used in water heaters. All these components all together work to make your morning shower so satisfying. The components include Tank, Dip tube, Shut-off valve, heat-out pipe, thermostat, heating mechanism, drain valve, pressure relief valve, and anode rod.

The thermostat is used to controller the temperature of the water inside the tank. Usually, you can set the temperature anywhere between 120 and 180 degrees Fahrenheit. The dip tube basically collects the cold water from your home’s water lines to the bottom of the tank’s interior. And, from this place, the water starts to warm up. At this time, the heating mechanism, which can either be an element or a burner, stays on.

The heating mechanism stays on until the water reaches the set temperature. The hot water rises to the top of the tank and is starts to take an exit from heat-out-pipe.  The simple principle on which the water heater operates is that the hot water rises above the cold water.

Types of Heaters/Geysers

  • Instant

These types of water heaters have small storage capacity and high heating rates. These water heaters provide hot water quickly. It usually takes about 1 minute on an average to heat water to useful temperature and 2 minutes to heat to high temperatures. Moreover, if you have a 3-litre instant geyser, the water will heat up almost instantly as you empty the tank. Showers however have a higher flow rate. Hence, you do not get water at the correct temperature to bathe.
