Voted No. 1 in BathroomElectric showers have become increasingly popular in recent years, offering a convenient and easy way to get hot water for your shower without relying on a central heating system. But how do they work, and what do you need to know before installing one in your home? In our latest guide, we’ll walk you through the basics of electric showers, including how they operate, what size cable you need, and some of the best options available.
How Does an Electric Shower Work?
An electric shower operates by heating cold water as it flows through the unit. When you turn on an electric shower, cold water from your home's supply is directed into the unit, where it's heated by an electric element. This element works much like a kettle, rapidly warming the water to the desired temperature before it flows out of the showerhead.
The temperature of the water is controlled by a thermostat, which maintains a consistent temperature by adjusting the flow rate of the water and the power supplied to the heating element. You can adjust the temperature manually using a dial or buttons on the shower unit.
How to Install an Electric Shower
Installing an electric shower can be complex - it requires connecting the unit to both the water supply and the electrical system. It’s highly recommended to have a professional handle the installation to ensure a safe and reliable setup.
The basic steps of the installation process are as follows:
- Identify a suitable location for the shower unit.
- Install the required plumbing to supply cold water to the unit.
- Connect the electric shower to the electrical system, ensuring the proper cable size and circuit breaker are used.
- Mount the shower unit on the wall and secure it in place.
- Connect the showerhead and hose.
- Test the installation for leaks, electrical safety, and proper operation.
Due to the complexity of the installation and potential safety risks involved, hiring a qualified plumber or electrician is the best way to ensure a safe and proper installation.
What Size Cable for an Electric Shower?
The size of the cable required for an electric shower depends on the power rating of the shower unit, the distance from the circuit breaker to the shower, and the local electrical regulations. Generally, higher power showers require thicker cables to safely handle the increased current.

Frequently Asked Questions About Electric Showers
Q. Is there much difference between 8.5 kW and 9.5 kW shower?
A. While the difference may seem small, a 9.5 kW shower can heat water more quickly and maintain a steadier flow rate than an 8.5 kW shower, especially in colder weather or if multiple appliances are using hot water simultaneously. However, a 9.5 kW shower also requires a larger electrical cable and may consume more electricity, so it's essential to consider your specific needs and infrastructure before making a choice.
Q. What are the advantages of an electric shower?
A. Electric showers offer several benefits over other types of showers, including:
- Independent operation: Electric showers don't rely on a central heating system, so you can have hot water even if your boiler is broken or turned off.
- Energy efficiency: They heat only the water you use, reducing energy waste compared to heating a large tank of water.
- Convenience: Electric showers can be installed almost anywhere with access to a cold water supply and an electrical connection.
Q. Is it cheaper to use an electric shower or combi boiler?
A. The cost of using an electric shower or a combi boiler depends on various factors, including local electricity and gas prices, the efficiency of the appliances, and the amount of water used. Electric showers are generally more expensive to run than combi boilers due to higher electricity prices. However, they can be more energy-efficient as they only heat the water you use. It's essential to consider your specific circumstances and compare the costs of both options before making a decision.
