Well actually I'm not sure if that is true but the makers of tap inserts say that they can save up to that amount - I fitted one at the weekend and certainly I have a smoother flow with less water - but not so noticeable as the spray is faster if you see what I mean - anyway I think they are well worth it - almost any saving will start to pay for itself in terms of savings on hot water especially if folk don't use a washing up bowl.
Tap inserts - see photo of me installing above - takes less than a minute and fits 85% of taps - see the brief video here about how to install.
Free showersave - at the moment both Wessex Water and Severn Trent (and maybe other water companies) are giving away free showerheads - see Severn Trent here - these are not the same as the whole showerheads - see next item - but do still save up to £40 per year - again well worth installing. The photo left shows the small device screwed into the shower - it takes 10 seconds to install!
Eco-Showerheads - well I've already fitted one of these a long while ago - and rave about how much I have saved of hot water - see photo left - it looks just the same as any other showerhead and takes about 10 seconds to screw off the old head and screw on the new - although my Eco-Camel at about £20 has now been outperformed by the NordicEco shower with a higher price tag - see a review here - if it saves all it says then the higher price is worth the money saved....
