Mira Showers by Power Rating

Electric showers are fantastically adaptive to their environments and will generally work on any domestic home's hot water system. There are however a number of factors that need to be taken into consideration and one of the trickiest is selecting which power rating you need. It will depend on what kind of electrical system you have and the size of your wiring so if in doubt consult a qualified installer. If you think about the power rating (or kilowatt rating) as a performance chart, the higher the number, the more powerful a shower you’re going to get and vice versa.

Made by a leading UK manufacturer with over 100 years of expertise, Mira showers are not only innovative but supported by exceptional customer service. Mira's electric options come in several different power ratings and styles to suit your home. Shop Mira electric showers below.

How do I decide which kW rating will give you a strong, hot shower at home?

Think of the kW as a performance number, higher kW usually gives more flow and hotter water. Mira models here run from around 7.5kW up to 10.8kW, so a small flat with modest mains supply will often be fine with 7.5–8.7kW, while a larger house that wants a more powerful spray will prefer 9.5–10.8kW. The product product information also shows practical wiring guidance. Use those kW bands to match the shower feel you want rather than just the model name.

What's the real difference between a standard electric shower and a pumped electric or dual‑head option?

A standard electric shower heats cold water on demand and is usually single‑outlet, whereas pumped electric showers include an integrated pump to boost pressure and are better where mains pressure is low. Dual‑head (or two‑outlet) models give you a fixed head plus a handset so you can use both independently or together; some Decor and Sport ranges offer dual‑head options around the 9.5–10.8kW bands. If you want a stronger, more luxurious spray in a weak‑pressure house, a pumped or Sport Max model with Airboost will deliver noticeably better performance.

Which temperature control should you choose, manual, thermostatic or pressure‑stabilised?

If you want simple, low‑cost control, manual models do the job but they rely on a steady water supply; thermostatic showers actively mix to hold the set temperature, so they're safer for households with children or elderly users. Pressure‑stabilised units (the majority in our range) reduce sudden spikes when other taps run and keep the temperature steady during showers. For the most precise control look at microprocessor or digital options if you value exact temperature and flow settings.

Which Mira range should you look at if you want a stylish finish and extra features?

For contemporary looks, the Decor range offers finishes like Warm Silver and Black Onyx and includes dual‑head options, while Azora brings a frosted glass aesthetic with thermostatic control. Sport and Sport Max models focus on performance, Sport Max adds features such as Airboost for a more vigorous spray. If you want pumped performance with refined styling, Elite SE pumped models combine both and sit in the mid‑price bracket in our range.

How do the number of outlets affect how you'll use the shower day‑to‑day?

One outlet gives you a single shower head or handset and keeps installation straightforward; two‑outlet models provide both an overhead head and a handset for flexible rinsing, useful in family bathrooms. Three‑outlet units add extras like body jets or a bath filler so you can run multiple functions separately or together. a dual‑head Decor 10.8kW lets you enjoy an overhead drench while keeping a handset for quick rinses, and the product list shows several dual‑head options around the current product price.
