A little know-how

Just so you know..

Understanding the mechanism

First, let's understand how exactly a electric water heater works. Starting with the basics, the electric water heater is capable of heating the water by using two heating elements.

Just like any other electrical components, these heating elements can be heated up with the help of electric current.

Now, how do the two heating elements differ?

The heating elements in the electric water heater are placed at the top and bottom. So, as soon as the cold water is released into the tank's bottom, the heating element located at the bottom commences its task.

The heating element located at the top does a guest appearance only when required. It functions only when there is full-on demand for hot water and thus delivers its performance by heating up the water only in the upper part.

The mechanism here involves rushing the hot water up above the top and in turn, sending in some cold water into the bottom. Thus, the heating element at the bottom continues its job. Both heating elements use separate thermostats.

How to track the issue?

Well, this requires no rocket--science. All you need is some tools, patience, and some common sense.

If you are getting an irregular supply of water i.e., fully hot water gushing out for a short span, then, you should check with the bottom heating element. Likewise, if you are constantly getting lukewarm water for a generous amount of time, then, the top heating element is susceptible to be replaced.
