The Mira Elite ST is a tank-fed (cistern-fed) pumped electric shower for use where
the mains water supply pressure is too low, unreliable or non existent, to operate a
conventional electric shower.
The Mira Elite ST features an internal pump unit which has been designed to provide
all year round performance, even at the highest ow rates which are necessary during
the summer months. The Elite ST has separate controls for power selection and
temperature/ow adjustment. The Elite ST must have its own separate cold water
supply from the cistern to ensure correct operation.
