The effects of winter on an electric shower

You might have noticed that when there is a  significant drop in the outside temperature, in the winter for example, the performance of your electric shower is also affected.

Why does the cold affect my shower?

The change in temperature can make a difference in two ways to your shower. Firstly, you might notice the water isn't getting as warm as it does during the rest of the year, while the other impact is that the flow rate of the water coming through the shower head may be reduced.

This is all down to the way electric showers work. Water is received via your home's mains supply and heated in a similar way to a kettle using two heating elements. The energy used to power your shower is shared between heating the elements and keeping the water flowing from the mains to the shower head.

Because of this, there is a balance between how hot your water is and the rate of your water flow.

However, what throws a spanner in the works is when it gets colder outside. This causes a reduction in the temperature of your mains supply and means that more power is required to heat your water to its usual levels when it passes through your shower.

As a result, the split between how your electricity is used shifts - so either less power is diverted towards maintaining a strong flow of water or the flow remains the same but the temperature suffers instead.

Safety Cut Out

Please note that if the flow rate is reduced too much in order to heat up the water to a very hot temperature, then the shower's safety thermal switch is activated, and the water becomes cold.

To resolve this issue, turn off the shower to allow it to cool down, and upon restarting make sure that the temperature is not turned on to the maximum, thus allowing a faster flow of water through the shower, which will in turn stop it from becoming over heated.
