The Best Showers for Combi Boilers

Welcome to the exhilarating latest entry into the Drench blog, where this week we check out the best showers for combi boilers. There’s never been so much choice when it comes to shower systems and, lucky for you, Drench’s expansive online store has the very best.

Stick with us as we first define what a combi boiler is, for those who do not know, then move onto the most suitable shower systems which you may wish to kit out your home with and why.


What is a Combi Boiler?

Before we dive specifically into the combi boiler, let’s clarify the 2 other main types of boiler system typically found in UK homes.

First, older homes may feature a gravity boiler system consisting of a cold water tank located in the loft and water cylinder in an airing cupboard on the first floor of the property. The water is brought down and heated en route to the shower. This is the oldest common boiler system and notorious for lacking water pressure – though this can be resolved with the use of shower pumps.

The second system, seen in modern homes, is the unvented boiler system. In this setup, a high pressure immersion boiler links to a water cylinder for efficient heating of high volumes of water.

The combi boiler is perhaps most common in newer homes and quite different to the 2 options just discussed. The combi boiler consists of a boiler without tanks or water cylinders, simply heating water as and when you need it.

If you have a small sized boiler somewhere throughout your home and no dedicated hot and cold water tanks then you can be certain of it being a combi boiler. Also, it should say it all over the manual!

If you do not have a combi boiler, do not worry – get in touch with us and we will be able to recommend an alternative to any of the fantastic showers we are about to reveal.



What Implications Do Combi Boilers Present Showers?

Combi boilers are regarded for providing the most reliable and high-pressure water supply, and can be combined with a shower mixer to up the amount of hot water available on demand. They are highly configurable when it comes to pressure, with most offering 1-5 bar pressure settings.

Combi boilers run off mains pressure and the result is a boiler that is dependable across electric, digital and mixer showers. Those with a larger hot water supply due to boiler size may prefer a mixer shower, thanks to the sheer power of its flow and boost capability over electric and digital shower systems.

Mixer showers open up multiple shower heads firing off a single shower delivery, and are a great way to maximise water efficiency within your home. They also look fantastic and provide an unrivalled showering experience.

Perhaps a mixer shower for the master bathroom and smaller electric showers throughout your home’s secondary bathrooms? Let’s help you make the most of your combi boiler...

So, our combi boiler-possessing home bathroom renovators – now that we have clarified your boiler variant, which of our thousands of showers for combi boilers may be best for you?

We thought about splitting our selections into each of the main types of shower including manual mixer shower, thermostatic mixer shower, electric shower, power shower, digital shower and the space-age smart showers that are becoming more and more popular – but we know you have stuff to do and so do we, believe it or not!

As such, we decided that a simple way to present the main variants of shower system available would be by separating our selection into exposed showers and concealed showers with a range of the above shower types featured in each.

We’ve also gathered showers that for the most part run at full performance on 1 bar pressure, enabling you to minimise the output of your combi boiler and save a great amount on energy bills while enjoying showers at full pelt.


Exposed Showers & Concealed Showers Explained

The difference here is simple but key.

With exposed shower systems, you will see all of the valve body located external to the wall with only the piping stored within. Elements of the piping may also feature external to the mounting wall for aesthetic purposes. The most common valves seen in the exposed shower is the bar valve.

Then, as you can guess, concealed shower systems feature only the controls on the mounting wall. All of the valves and pipework are located within the wall. The result is a sleek and stylish setup that is incredibly neat and minimal. Each option has its perks, so let’s start our shower showcase for combi boilers and see which style takes your fancy.
