Norway has particularly hard water, and this showerade design has realised much success here for its unique ability not be be affected by limescale. Parts of the UK and Ireland also have hard water problems because of the calcareous/limestone bedrock in the ground source. Although water sourced from this rock type has benefits for bone growth and density - these same features may require showerheads to be descaled or disposed of regularly.
Limescale build up occurs when:
A) A change of pressure - such as at the exit point of a showerhead. Pressure change is particularly exagerated in high pressure systems, in aerated venturi systems and narrow outlet points.
B) Aeration will hasten the percipitation of calcium deposits as the conversion of Calcium Bicarbonate to Calcium Carbonate as the air added shifts this reversible raction over to the deposition side.
C)Limescale build up also occurs on evaporation of water las the last drops leave the showerhead and when water within the showerhead cool - thus hastening the laying down of the limescale load.
Solution - The Nordic Shower does not have a sieve plate with many small holes to block - but one large outlet point which is designed so that limescale cannot build as the last droplets leave the showerhead .
The first Hotel to install the showerhead was the Radisson in Oslo where standard showerheads had to be descaled every quarter. The same showerheads have been in place for 8 years now without requiring descale maintenance since the Nordic Shower were installed.
Guarantee - The unique design of the Nordic Shower mean that limescale build up will not affect the performance of the showerhead, regardless of maintenance- guaranteed. No other showerhead can offer this.
