What is the best type of shower to install and use with a modern combi boiler? Here we explain.
Looking for the right shower to go with a combi boiler?
Whether you have a combi boiler installed already and want to know which is the best shower to have added or you want to think ahead for a future combi boiler installation, you’ve come to the right place.
Let’s dive straight in…
What is the Best Type of Shower for a Combi Boiler?
What’s the Best Type of Shower for a Combi Boiler?
The thermostatic mixer shower is generally the best choice for a home with a combi boiler — especially if you live in a busy household.
Why? Because thermostatic mixer showers automatically regulate temperature and pressure.
That means no nasty surprises if someone else turns on a tap or starts running a bath mid-shower. You’ll enjoy consistent heat and flow from start to finish.
In short:
✅ Great temperature stability
✅ Ideal for combi boilers’ high-pressure hot water
✅ Safe and reliable for families
Still, thermostatic mixer showers aren’t your only option.
What Other Showers Go Well With A Combi Boiler?
A thermostatic mixer shower is probably the best-suited shower type to go with a combi boiler.
However, there are a few other choices worth considering:
Electric Showers
Another type of shower that matches well with a combi boiler is that of an electric shower.
One key advantage of electric showers is that even when a boiler breaks down, they can still heat water independently of the boiler.
Since an electric shower only requires mains water supply pressure, thus if you want to add a shower pump, a combi boiler would be necessary.
With that said, when it comes to showering on a daily basis, a thermostatic mixer shower or digital shower would be best for a combi boiler.
Digital Showers
As touched on, a digital shower is more suited for a combi boiler than an electric shower.
But what is a digital shower?
A modern digital shower is made specifically to work with high-pressure systems like combi boilers.
Digital showers are somewhat similar to thermostatic mixer showers.
This is because they too respond to temperature and pressure variations in real-time should another person in your home also attempt to use hot water while you’re showering.
Moreover, digital showers allow users to set presets to enjoy the ideal showering temperature each time. Lastly, digital showers are aesthetically pleasing and up-to-date.
But What About Power Showers?
Unfortunately, power showers aren’t a good match for combi boilers. This is because they are meant to be used with low-pressure water supplies.
As a result, they are not a suitable match for combi boilers.
With that said, with three standout options (as discussed in the previous two sections), you have plenty to choose from.
That isn’t simply in terms of the type of shower you opt for but the actual shower model you go with.
Finding the Right Shower Model for You
Whether you opt for a thermostatic mixer shower, digital shower or even an electric shower, there are many shower units available on the market.
We suggest narrowing things down based on your budget, preferences and priorities.
Either way, when trying to decide which shower is best for you, be sure that it is well-suited to your home and specific combi boiler. If in doubt, consult a professional.
A Quick Recap: Why Combi Boilers Are Unique
Combi (or combination) boilers provide heating and hot water directly from one compact unit — no separate cylinder or tank required.
That’s why they pair best with showers designed for high-pressure, on-demand water flow.
Key Advantages:
Instant hot water, no waiting
Compact and space-saving
Highly efficient and modern
Lower installation and running costs
Consistent pressure and temperature
A Few Drawbacks:
Not ideal for very large homes with multiple bathrooms
Hot water flow can slow if several outlets are used at once
You’ll lose both heating and hot water if the boiler breaks down
(Though, as mentioned - that’s where an electric shower can come in handy.)
The Bottom Line
If you’ve got (or are planning to install) a combi boiler, your best bet is a thermostatic mixer or digital shower - both provide stable pressure, reliable heat, and that all-important “ahh” factor every morning.
Electric showers can still make sense as a backup, but steer clear of power showers altogether.
