University of Bath Laboratory Trial

*These tests were performed in June 2000 on a Super Imp which is equivalent to our current WaterImp Original model. Since then we have continued our development and have introduced new and more powerful versions of all our electronic water conditioners whilst keeping the price the same.*

Figures 1 and 2 show two sections of piping after a 30-day trial conducted by the Department of Chemical Engineering at Bath University. The objective of this trial was to evaluate whether or not a Super Imp Limescale remover could reduce the level of scale formation within domestic hot water / radiator heating system.

Figure 1 shows a section of pipe from the system that had a Super Imp installed. The pipe looks exactly as it did when the experiment was started.

Figure 2 shows a section from the system without a Super Imp installed. Scale formation can clearly be seen on the inside wall of the pipe. Remember this is only after 30 days.

The Experiment’s Conclusions:

  • The Super Imp device has been shown to reduce the deposition of scale under the conditions tested. This has been confirmed by analysis of both total dissolved solids and conductivity in parallel trials using a simulated domestic hot water / radiator heating system.
  • The Super Imp has prevented the deposition of about 10 mg of scale/day for 30cm length of 1 inch pipe under the conditions tested.
  • The Super Imp device has been shown not to effect the pH of water passing through piping where it has been installed.


1. Choose the right WaterImp for your home

Choose your WaterImp based on the size of your home

2. Fit it quickly & easily yourself


3. Say goodbye to your hard water problems and save money!


What our customers say

Running for over 20 years

“Over 20 years ago my mother bought a Water Imp for herself and for me. Over the years I had reason to ring for advice which always resulted in my Imp continuing to work. Sadly today my Imp has passed away and has to be replaced by another one, I would like to say that in this throwaway world we live in that I consider this to be pretty amazing, and of course, would recommend the product.

Still going strong!

“Greetings from Austria! Can’t remember how long ago we bought our unit, but it’s still in use!”

I would highly recommend

“I have had my water imp now for about three weeks and from the first day it has worked great. My hand soap now suds as well. In a few short words I would recommend highly.”

Simply amazing

“We wanted to update you on the two water conditioners. They are doing a fantastic job. They were installed around the second week in December and we didn’t tell anyone. The family noticed the change within the first week!…. Simply amazing and simple.”
