Overview

The Mira Sport 9.8kW is one of the most widely installed electric showers in the UK. It heats cold mains water on demand, so it works in any property regardless of the boiler type or hot water system. The thermostatic stabilisation technology maintains a consistent temperature even when other taps or appliances draw water elsewhere in the house, solving the common complaint of temperature fluctuations in older electric showers.

In-Depth Look

Electric showers remain essential in the UK market. They provide hot water on demand without relying on a boiler, making them the standard choice for en-suites, second bathrooms, and properties where the hot water system cannot support multiple outlets simultaneously.

Thermostatic Stabilisation

The key feature that sets the Mira Sport apart from basic electric showers is its thermostatic stabilisation. When someone runs a tap or flushes a toilet elsewhere in the house, the cold mains pressure to the shower drops momentarily. In a basic electric shower, this causes a sudden spike in temperature. The Mira Sport detects this pressure change and compensates, maintaining a consistent shower temperature.

Electrical Requirements

A 9.8kW electric shower draws significant current and requires a dedicated 40A circuit with 10mm2 cable. The cable size may need to increase for longer runs. This is a job for a qualified electrician, and Part P notification or certification is required. Installers should verify the existing consumer unit can accommodate the additional circuit before quoting the job.

Verdict

The Mira Sport 9.8kW is the dependable electric shower that works in virtually any UK property. The thermostatic stabilisation genuinely improves the showering experience, and Mira’s UK-based support and parts availability give both installers and homeowners long-term confidence.
