Understanding Electric Showers

If you’re looking to increase the power of your electric shower, it’s important first to understand how it works. Electric showers are a popular choice in the UK, providing hot water on demand without the need for a hot water tank. They work by heating the water as it passes through the shower unit, providing an instant and constant supply of hot water.

The power of an electric shower is determined by two main factors: the kilowatt (kW) rating of the heating element and the water flow rate. The higher the kW rating of the heating element, the more powerful the shower. Similarly, a higher flow rate will increase the power of the shower, providing a stronger and more invigorating experience.

In addition to the heating element and the water flow rate, the size of the showerhead can also impact the power of the shower. A larger showerhead will spread the water over a wider area, reducing the pressure and ultimately resulting in a less powerful shower. Therefore, when looking to increase the power of your electric shower, it’s important to consider all of these factors.

Checking and Adjusting Water Supply

One of the key factors affecting the power of your electric shower is the water supply. If the water flow rate is too low, your shower may feel weak and ineffective. Fortunately, there are several steps you can take to increase the water flow and amplify the shower’s strength.

Checking the Flow Rate

The first step is to check the flow rate of your shower. To do this, turn on the shower and place a bucket or large container beneath the showerhead. Let the water flow for one minute and then measure the amount of water collected. A flow rate of at least 9 litres per minute is recommended for an electric shower to function at its best.

If the flow rate is lower than 9 litres per minute, there may be an issue with the water pressure or a blockage in the pipes. You can try removing shower filters or cleaning the pipes to increase the flow rate. If this doesn’t work, it’s best to contact a professional plumber to investigate further.

Adjusting the Water Pressure Regulator

Another option to consider is adjusting the water pressure regulator. This is a valve located on the main water supply pipe that controls the pressure of the water entering your home. If it’s set too low, it can affect the flow rate of your electric shower.

You can adjust the pressure regulator yourself by turning the screw clockwise to increase the pressure or counterclockwise to decrease it. However, it’s important to be cautious when adjusting the pressure, as setting it too high can lead to other issues in your plumbing system. If you’re unsure, it’s best to consult a professional plumber.
