The Galaxy Aqua 4000si is a stylish electric shower with rotary and push button controls for ease of use and with advanced safety features included as standard. This makes it a good choice for a family friendly shower for modern bathrooms, especially in hard water areas and homes affected by limescale build up. The TempSure Plus technology reacts to changes in water pressure to stabilise the showering temperature for comfort during use. This prevents any extreme spikes in the water temperature during showering. The Aqua 4000si features unique Scalemaster coated protection on the heating elements to prevent scale build up from particle adhesion and crystallisation. An electrolytic inhibitor helps neutralise any effects of scale build up which significantly prolongs the life of your shower. Limescale build up of just 1/8th coverage will reduce heating efficiency by 20%, so Scalemaster is the effective way to combat this and to maintain the performance of your shower, all with the reassurance of a 2-year guarantee against the effects of limescale build-up. Additionally the ScaleCheck feature flushes out residual water after use to ensure a safe and comfortable starting temperature for the next user, while also removing the heated water prevents any additional scale build up. If you suffer from hard water problems, or live in a hard water area this shower would be a good consideration, either for new installations or if replacing an existing shower. In use the logical easy-to-turn controls have clear markings and are supported by LED indicator lights for power setting selection and a low pressure indicator warning light. There are electronic push button controls for power selection and stop/start, with a large rotary dial for temperature/flow adjustment. You can start and stop the shower with one touch of the electronic button, this will also retain the last selected temperature and power settings for the next use. The rub clean showerhead has six different spray patterns, from scintillating to soothing, to suit your mood for a more individual showering experience. The SlideFit wall rail kit has an adjustable wall bracket so there is no need to drill new holes; simply match up with and re-use the existing wall fixing holes. The plumbing inlet connection, terminal block power connection and associated entry points are all located on the right hand side of the shower. The Aqua 4000si provides advanced showering with performance and safety technology as standard, for family friendly showering enjoyment time after time.
