One of the key issues is that limescale can build up around 'hot spots' within your shower 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, which flushes hot water from the shower after use to keep your electric shower in great condition, this is only available in certain Mira electric shower so we recommend checking the individual products.
