Choosing the right boiler can significantly enhance your showering experience, providing a powerful and reliable flow. Your boiler type and how your hot water for showering is supplied also impacts your water and energy bills.

In this article, we’ll explore the factors to consider and recommend the best boiler options for a satisfying power shower in the UK.


How Does A Power Shower Work?

If you are experiencing low water pressure in your home, you might be considering installing a power shower to boost your water flow. A power shower system is made up of a mixer valve that combines water from your hot and cold water supply, and a pump which helps increase the water pressure for a stronger shower experience.

However, for a power shower to function properly, it requires a reliable and efficient boiler system that can supply sufficient hot water at the required pressure.


Key Factors to Consider When Choosing The Best Boiler For a Power Shower:

  • Water Pressure: A power shower relies on adequate water pressure to deliver a forceful spray. Therefore, your boiler should be capable of maintaining consistent water pressure, especially during peak usage times.
  • Flow Rate: The flow rate of your boiler determines how much hot water it can deliver per minute. For a power shower, a boiler with a high flow rate is essential to ensure a steady stream of hot water.
  • Compatibility with Mixer Showers: Power showers incorporate mixer valves to blend hot and cold water. Your boiler should be compatible with mixer showers to ensure seamless integration and optimal performance.
  • Energy Efficiency: Choosing an energy-efficient boiler not only reduces your carbon footprint but also helps lower your energy bills. 


What Is The Best Boiler Type For a Power Shower?

Our top recommendation for a power shower is a system boiler. Unlike conventional boilers, which require a separate cold water storage tank, system boilers operate with a hot water cylinder, providing an efficient and space-saving solution. 

With a system boiler, hot water is produced on demand, eliminating the need for a cold water storage tank in your home. This not only frees up valuable space but also ensures a constant supply of hot water whenever you need it, ideal for powering a high-performance power shower.


Can I Install a Power Shower With Combi Boilers?

Combi boilers are a popular choice for UK homeowners due to their compact size and ability to deliver hot water on demand. They are well-suited for smaller properties or households with limited space. As combi boilers lack access to a hot water cylinder, a power shower is incompatible with a combi boiler. 

But fear not! Combi boilers are ideal for other shower types, including electric and thermostatic mixer showers, and you will still be able to experience a great showering experience.

It is with noting that if there are multiple shower users at one time, your combi boiler will struggle to supply water to multiple places simultaneously and the pressure will be affected. Straining your boiler in this way will also likely lead to shortening its lifespan and you could need costly boiler repairs


How Can I Increase the Water Pressure In My Shower?

Increasing water pressure in your shower can significantly enhance your showering experience. If you are constantly losing pressure, start by checking for any obstructions or leaks in the pipes leading to your shower. Sometimes, buildup or blockages can restrict water flow, causing reduced pressure. 

You could also consider installing a high-pressure showerhead which can help amplify the water flow. 

If the problem persists, it might be caused by issues with your boiler. Sometimes you can carry out some quick fixes at home, but if the problem persists you might want to consider a professional boiler service.



Choosing the best boiler for a power shower requires careful consideration of water pressure and compatibility with your hot water system. Our recommendation would be to install a system boiler as this is a reliable boiler that ensures consistent water flow and temperature. Unfortunately, combi boilers will not be a good fit if you are considering a power shower however will still work excellently with other shower types, and are often cheaper to operate.
