Water Heater using GI wire – School Science Experiment


Water that comes into our taps from the tank is usually cold because it is groundwater. During cold weather conditions, it becomes difficult to use the normal water running through the tap. That’s when hot water requirement comes into the picture.

This need has been satisfied by the invention of water heaters. Water heater warms up or heats up the normal water using a thermostat that is fixed inside the cylindrical enclosure. The thermostat controls the temperature of water inside the tank.

We can set the temperature of the water depending on our need, which is visible through an indicator that switches off when the set temperature is reached.

In this video, we show how to make a simple water heater with the help of GI Wires in place of spoons and which is safe as well. Please do not try this at home and if you need to try please do it under the guidance of an expert.

Questions and Answers:

  1. What are the pats of a water heater?

A. The parts of electric water heater are tank, dip tube, shutoff valve, heat out pipe, thermostat, drain valve, pressure relief valve and anode rod.

2) What is a thermostat?

A. Thermostat is a temperature control device. When the heater reaches a temperature, it is set to for use, the thermostat shuts off the heater. And when the water is too cold and has to be heated, it switches on the heater.

3) What are the types of water heaters currently available?

A. There are various types of water heaters available in the market, they are, electric water heaters, Solar powered water heater, heat pump water heater, condensing water heater and conventional storage tank water heater.

4) How to maintain a water heater?

A. In most of the conventional water heaters, thermostat plays a key role. So, when ever the water heater gets for repair, mostly the element in the thermostat burns up. Replacing the thermostat will resolve the problem.


In this urban generation, water heaters have become a necessity rather than a luxury. Thus, according to the need there are many types of water heaters that have come into the market. Depending on the need and cost, people choose a water heater for their homes.

Among many types of water heaters, solar water heaters are more preferable as they don’t need much electricity and very easy to maintain.
