While each electric shower model has its own individual features, they all heat water the same way.

Having a brief understanding of how an electric shower works, and some of the factors that can affect their performance will help you choose the right electric shower for you.

Here's a quick rundown.

Cold water is drawn into the unit and heated by one or more powerful electric elements as it passes through the unit.

Increasing the temperature you want from your shower will decrease the flow of water from the showerhead.

This is because the water needs to stay in the unit longer for the elements to heat it to your increased temperature requirement.

On the other hand, decreasing the temperature you want will increase the flow of water from the showerhead.

Of course, in this case the water is heated to the required temperature quicker and therefore flows through the unit faster.

And that's not the only thing that can influence the flow of water from your showerhead.

Things like the electricity supply voltage, the kilowatt rating of the shower and the incoming temperature of your cold water all affect the flow of the water.

So, for example, expect the flow rate to change with the seasons. During winter, the cold mains water supply will make it harder for the shower elements to warm up the water to the required temperature. As a result, water flow will be a little lower.

During the summer months, when the cold water entering the shower is warmer, the flow rate will be higher.

For more information on kW ratings, take a look at our "What is a kW rating?" video.

OK, finally I'm sure at some point you have experienced a small spike in the water temperature while showering.

This is because the electric shower is a temperature stabilised shower and is only able to maintain the water temperature to within 5oC when there is a pressure change in the incoming water supply.

So, for example, if someone turns a cold water tap on elsewhere in the house, the cold water pressure to the shower will drop, reducing the flow of water and resulting in an increase in the water temperature.

If your cold water supply has a large demand from washers, kids and more -- then maybe you should consider a thermostatic electric shower.

These showers can maintain the water temperature to within 1 to 2oC. They can do that, not only when your water pressure changes, but also when the incoming temperature of your cold water or electric supply voltage changes.
