Flow rate
When it comes to electric showers, one of the key factors that determines their performance is the flow rate, which is measured in litres per minute (L/min). A higher flow rate generally means a more powerful shower, as it indicates a higher volume of water being heated and delivered per minute, resulting in a more invigorating shower experience.
Electric showers typically range in flow rates from 2 L/min to 14 L/min, with an average of around 6 to 8 L/min. The higher the flow rate, the more water is used, which can impact your water bills and environmental footprint. Therefore, it's important to consider not only the power but also the efficiency of the electric shower.
Some modern electric showers feature water-saving technologies that restrict the flow rate to a maximum of 8 L/min, striking a balance between performance and sustainability. These water-saving showerheads use innovative designs, such as multiple spray patterns and air-mixing chambers, to maintain a satisfying shower experience while reducing water consumption.
When selecting an electric shower, it's essential to consider not only the flow rate but also other factors such as water pressure, temperature control, and energy efficiency. Water pressure plays a crucial role in the overall performance, as insufficient pressure may result in a weak shower, regardless of the flow rate. Therefore, ensure that your plumbing system can provide adequate water pressure to support the desired flow rate.
Additionally, look for electric showers with precise temperature controls and thermostatic features, which ensure a consistent and comfortable showering experience. Some advanced models offer digital temperature displays and controls, allowing you to fine-tune the water temperature to your preference. Energy efficiency is another important consideration, as it not only reduces your environmental impact but also helps lower your electricity bills. Look for energy-efficient models that utilise

Thermostatic Control
Thermostatic control is a crucial safety feature in electric showers, ensuring that the water temperature remains consistent and safe for users. This feature is especially important for families with young children or elderly members, as it prevents accidental scalding. The Mira Showers Azora 9.8 Kw Thermostatic Electric Shower, for instance, offers thermostatic control for safe family use.
Sensi-flo Technology
The Mira Showers Sport Max Electric Shower and the Mira Azora model are equipped with Sensi-flo technology, which is a safety innovation that prevents scalding. It achieves this by responding to temperature fluctuations and detecting potential blockages in the showerhead or hose. If a blockage is detected, the shower cools down swiftly, ensuring the user's safety.
Maximum Temperature Limit
Some electric showers feature a maximum temperature limit, which prevents the shower from being manually turned up to unsafe temperatures. This safety feature is particularly useful for families with young children, as it eliminates the risk of accidental burns.
Phased Shutdown
Phased shutdown is a safety mechanism that gradually runs cool water through the shower after use, ensuring that the water temperature decreases safely. This feature is designed to prevent scalding and make the shower safe for the next user. The Bristan Joy 3 electric shower, for instance, incorporates a phased shutdown along with a "warm-up mode" for added safety.
Limescale Protection
Limescale buildup is a common issue in electric showers due to their heating elements. Manufacturers offer various solutions to this problem, such as Clearscale Technology in the Mira Showers Sport Max model, which reduces limescale buildup by up to 50%, enhancing the longevity and performance of the shower.
Overheating Protection
Electric showers have a built-in safety feature that cuts power to the heating element if it gets too hot. This mechanism prevents the shower from overheating and ensures the water temperature remains safe for users.
When selecting an electric shower, it is important to prioritize safety features to ensure a comfortable and secure showering experience for all household members.
