I'm a bit confused about the savings difference between your "ShowerSave" and "Water Efficient Showerhead" freebies!
Your site gives flow and savings information for both devices based on a family of four:
It says the ShowerSave is capped at 8lt/min and could save up to 31,200 litres of water and £126 a year.
It says the Water Efficient Showerhead is capped at 6lt/min and could save up to 21,840 litres and £87 a year.
What I don't understand is how the ShowerSave which caps at 8 litres a minute can possibly save more water than the showerhead which is capped at 6 litres a minute? Assuming both are exclusively used for showers, surely it should be the showerhead that is saving more water / energy?
