This guide will unravel the mysteries surrounding one crucial component – the boiler. Join us on this captivating journey as we explore why a boiler is necessary for your electric shower and how it transforms your daily routine into an extraordinary experience. 

 With expert advice on choosing the right system for your needs and any extra safety considerations or maintenance tips you may need. Installing an electric shower and boiler is a big decision, but it can affect your home’s energy efficiency and comfort 

What is a Boiler?

A boiler is a device that uses steam, hot water, or other fluid to produce heat. This heat can then be used for various things, such as heating your home or office, powering industrial equipment, or making fabrics and other materials soft and pliable. 

Boilers come in different shapes and sizes, but all work the same way. Inside the boiler, water is heated up until it turns into steam. This steam then works its way through the boiler system and produces heat. The heat from the steam can be used to power different devices in your home or office, or it can be used to make things like fabrics and plastics soft and pliable.

How Does a Boiler Work?

A boiler is a machine used to produce hot water, steam, or heating oil. Boilers are made of different materials and can be either electric or gas-fired. They work by using heat to turn water into steam, which then spins the electric motor that powers the equipment in your shower. 

Electric boilers come in two types: forced-air and condensing. Forced-air boilers use an air compressor to push air through the boiler tubes. This causes the water to reach a higher temperature than a condensing boiler, but it also requires more maintenance because dirt and dust can block the airflow. Condensing boilers use a liquid coolant, such as water or oil, to lower the boiling point of water so that it can vaporize without turning into steam. This method is less likely to produce dirty vaporized water but requires a separate cooling system.

Understanding Electric Showers

An electric shower is an energy-efficient option for hot showers. It uses a heating element to heat up water on demand quickly, so you don’t need to keep a large amount of heated water in a storage tank. This saves energy and money since the heater only needs to work when you start your shower. 

 Why Do Electric Showers Need Boilers?

While you may not need a boiler for your electric shower, it’s still important to have one in the system. This is because the boiler can provide a steady supply of hot water to your shower, meaning you don’t have to wait for it to heat up. Without the boiler, you would likely experience fluctuations in temperature or pressure when using the shower. 

It’s also important to note that electric showers require a certain amount of power and amperage to operate correctly. 

The power required is determined by the size of your electric shower unit and other factors such as water pressure, temperature, etc. Without a boiler, it would be difficult to guarantee that the amount of power needed for your electric shower will remain constant. 


The benefits of having a boiler for your electric shower are many. Boiler technology is more efficient than traditional heating methods. It helps to reduce your electricity bill.

Additionally, a boiler can heat water evenly, which is vital for smooth, enjoyable showers. A boiler eliminates the need for hot water tanks and other plumbing fixtures in your bathroom.


Electric showers are becoming popular but come with a few disadvantages many people may need to learn about. 

  • Electric showers don’t work well in cold weather because the water can’t heat enough. 
  • Additionally, if your electric shower doesn’t have a boiler, you’ll need to run an extension cord from the outlet to the shower head, which can be inconvenient and costly.
  •  Electric showers with boilers are more effective because they produce less water pressure.

Safety Considerations 

Using an electric shower connected to a boiler also ensures safety for your home. Boilers keep water at temperatures over 65 degrees Celsius.

 It helps to kill bacteria and other harmful microorganisms that cannot survive. This helps reduce the risk of contamination in your home, keeping you and your loved ones safe from potential health risks. 

Choosing The Right Electric Shower For Your Needs

When it comes to choosing an electric shower for your home, it’s important to take into consideration factors such as 

  • temperature control
  • water pressure
  • safety. 

Different electric showers will provide different levels of features and functions, so it’s essential to research before making a purchase. Additionally, having an expert inspect your electric shower system can help you ensure all components function safely. 


Can you have an electric shower without a combi boiler? 

Yes, you can install an electric shower without a combi boiler. You may need to install a separate hot water tank for your electric shower to work. 

How does an electric shower get hot water?

An electric shower works by heating cold water as it passes through a heating element via an internal pump. This is why ensuring you have the right size and type of boiler is essential – otherwise, your electric shower may need to get hotter! 

Are electric showers safe? 

Yes, electric showers are generally safe when installed and used correctly. However, it’s essential to follow all safety guidelines and regulations related to plumbing, electricity, and gas when installing or using an electric shower. 

Final Thoughts 

In conclusion, Do electric showers need a boiler? Yes, electric showers do need a boiler in order to provide hot water. Taking the necessary precautions to ensure your system is safe and functioning correctly can help you have a worry-free experience when it comes to enjoying hot showers in your home.

Electric showers connected to boilers provide a unique combination of 

  • convenience
  •  efficiency
  •  and safety. 

If you’re looking for an easier way to enjoy hot showers, installing an electric shower with a boiler is the perfect solution. Proper installation and regular maintenance allow you to enjoy consistent hot water in your home for years!
