Mira Clearscale™ Technology

March 23rd | | News
Blog image

You may have noticed a hard and chalky residue left behind in your household products, this is known as limescale and is most likely to be found if you live in an area with ‘hard water’. It can be difficult to gage whether you have a build-up of it in your shower or a faulty piece of equipment. In most cases your supplier will be able to let you know whether you are likely to experience issues due to the water quality in your area.

If you are struggling with your product, our team here at Mira Showers have put together this simple checklist to rule out whether or not you have limescale:

  • Failure of heating elements
  • Poor temperature control
  • Taps or hard surfaces covered in an unsightly layer
  • Clothes detergents/soap become less effective
  • Products become less energy-efficient

Mira Clearscale™ Technology

One of the key issues that limescale causes is its build-up within the ‘hot spots’ of your system. To eliminate this issue, the Mira Clearscale™ technology in our electric showers works by lengthening the heating elements as well as widening the gaps between the coils. This means that the heating tank runs at a consistent temperature throughout, eliminating the chance for ‘hot spots’ and the build-up of limescale. To help prevent the problems that come with limescale, a delayed shutdown is also included in the system, which flushes hot water from the shower after use, keeping your electric shower in tip top condition!

Unless you are a professional, it is difficult to be able to look inside your own shower; therefore you might be unaware of limescale build up in your shower until its performance is impaired as a result. We are dedicated to solving the issue, and we are permanently undertaking research to explore, monitor and test the growth of it, so it can be better understood. We first of all complete accelerated life testing on our units at a business called Hydramec who are located in a hard water area of Norfolk. Once this is completed, we then send the tests to Cranfield University who then assess the output. We decided to illustrate the exact benefits of our Clearscale™ technology with a film highlighting the level of limescale in any ordinary electric shower:-

Mira Showerheads


It’s not just our electric showers than combat limescale build up. Our showerheads feature rub clean nozzles which allows the user to use a soft cloth to wipe any limescale from the nozzle and front face of the showerhead. If you’re living in a particular hard water area we would recommend the Mira Everclear showerhead which is suitable for mixer showers above 0.2 bar and electric showers over 9kW. It has been specifically designed with an automatic self-drain action and pins to resist limescale build up.
