The Mira Excel BIR Thermostatic Concealed Mixer Shower combines precise temperature control with a clean, understated installation. With the valve and pipework concealed behind the wall, the visible controls take up minimal space while still giving you independent adjustment of both temperature and water flow.

For anyone comparing concealed valve mixer showers, the Excel also combines Mira's Magni-Flo™ technology with thermostatic control and a versatile four-spray showerhead, delivering reliable performance across a wide range of plumbing systems.

Separate Temperature and Flow Controls

Rather than relying on a single control for everything, the Excel allows you to adjust the temperature and flow independently.

This makes it easy to fine-tune the strength of the spray without altering your chosen temperature, giving you greater control over your everyday showering experience.

Precise Thermostatic Temperature Control

Changes in pressure or temperature elsewhere in your plumbing system can cause ordinary showers to suddenly become hotter or colder. The Mira Excel uses thermostatic technology to recognise these changes and automatically adjust the hot and cold water supplies.

This helps keep the shower close to your selected temperature, providing a more consistent and comfortable experience.

Maximum Temperature Stop

A built-in maximum temperature stop helps prevent an unsafe temperature from being selected accidentally.

If a higher temperature is required, the stop can be deliberately overridden using a discreet push button, providing additional control while reducing the chance of accidental adjustment.

Mira Magni-Flo™ Technology

Mira's Magni-Flo™ technology optimises the internal waterways through the valve to improve shower performance.

Mira states that Magni-Flo can provide up to three times more flow than similar mixer showers, with the Excel designed to provide impressive performance even on suitable systems with water pressure as low as 0.1 bar.

Four Spray Patterns

The supplied Mira Logic showerhead gives you four different spray patterns to choose from:

• Start — A balanced spray for everyday showering
• Soothe — A gentler spray for a more relaxing shower
• Force — A more concentrated, invigorating spray
• Eco — Designed to provide a satisfying shower while using less water

Changing between the settings allows different members of the household to personalise the shower to their preference.

Easy-Clean Showerhead

The Mira Logic handset is designed for straightforward cleaning, helping you remove deposits from the showerhead and maintain good spray performance over time.

Designed to Resist Limescale

The Excel incorporates ceramic plate technology designed to resist limescale build-up within the valve. This can be particularly useful in hard water areas, helping maintain smooth and reliable operation over time.

Accessible Filters

Large filters help protect the internal valve from debris within the water supply and are designed to be easily accessible when maintenance is required.

Mira states that shower performance remains unaffected even when the filters are up to 50% blocked, helping maintain consistent performance between servicing.

Suitable for a Wide Range of Water Systems

The Mira Excel is compatible with a broad selection of domestic plumbing systems, including:

• Gravity-fed hot and cold water supplies
• Pumped gravity-fed hot and cold supplies
• Fully modulating combination boilers
• Instantaneous gas water heaters
• Unvented mains-pressure hot and cold systems
• Mains-pressure thermal stores

This versatility makes the Excel a practical choice whether you're replacing existing mixer showers or planning a completely new bathroom.
