How do electric showers work?
If you're wondering how electric showers work, they function by heating water as it flows through the unit using an electric element. The electric element, usually made of a metal alloy, is responsible for generating heat when an electric current passes through it. As the water passes over the electric element, it absorbs the heat and becomes hot.
The temperature of the water can be adjusted using the shower controls. To increase water pressure in an electric shower, you can check if the showerhead is blocked and clean it if necessary. Using a powerful electric shower has several benefits, including a more invigorating shower experience and higher flow rate.
What makes a powerful electric shower?
Wattage plays a crucial role in determining the power of an electric shower. The higher the wattage, the more powerful the shower will be, in this article we have focussed on the highest kW output showers from Mira, Triton, Aqualisa and Bristan, these showers are normally either 10.5kW or 10.8kW. These are the most electric showers that you can buy today, however they do need a dedicated 10mm cable to them so may not be suitable as a retrofit for an existing shower.
It is also important to note that no electric shower will provide the kind of experience that a good high pressure mixer shower will, your average 30kW combi is producing 3 times as much hot water as any of the showers in this article. You can however make up some of this difference by changing the shower head to an aerating type to give the same kind of experience.
To get a powerful electric shower, you also need to consider the importance of water pressure. Your homes water pressure needs to be high enough for an electric shower to function correctly as they are plumbed in to your homes mains water supply.
If you don't have an adequate power supply for a 10.5kW+ shower then check out our article on the best electric showers you can buy today for options that are more suitable.
Importance of water pressure for a powerful shower
Ensure that you have sufficient water pressure for a powerful showering experience with an electric shower.
The importance of water pressure can't be overstated when it comes to enjoying a powerful shower. Low water pressure can result in a weak flow of water, making your shower feel underwhelming and unsatisfying.
Additionally, there are various low water pressure solutions available, such as aerated shower heads and water-saving devices, that can help improve the pressure and enhance your shower experience.
With sufficient water pressure, you can enjoy a truly powerful and invigorating shower.
How the wattage affects the power of an electric shower
To maximise the power of your electric shower, it's important to understand how wattage directly affects its performance. The wattage of an electric shower determines the amount of power it can produce, which in turn affects the water flow rate and temperature.
Higher wattage electric showers generally have better performance, providing a stronger water flow and quicker heating.
