Do You Live in an Area with Hard Water?
It's quite possible that you do, because approximately 65% of the UK population is supplied with hard water containing a naturally high incidence of calcium and magnesium mineral salts.
Type of water can vary dramatically across the UK from soft water to moderately soft to very hard water. Most areas of England, particularly the east between the Severn and Tees estuaries, are considered to be 'very hard'. Wales, Devon, Cornwall and parts of North-West England are softer water areas
See if you are affected by hard water by downloading the FREE HARD WATER APP for Android smart phone and iPhone - available from Google Play or Apple App Store, just search SESI.
What is SESI?
SESI is a device which, when fitted to the incoming water main of your home, offers whole house protection against the effects of hard water.
An electrolytic device, it works by a natural electrolytic process, releasing a tiny amount of zinc ions which interfere with the formation of limescale crystals. This stops the crystals from binding together or clinging to surfaces. This prevents the build up of limescale. Simple.

SESI to the Rescue
The average life of a boiler heat exchanger is 10-15 years. In hard water areas, this can be cut by nearly 80%, reducing the life expectancy to just 2-3 years.
By installing a SESI, you can restore system efficiency and minimise the damaging effect that scale has upon appliances and system components.
- LOWER FUEL BILLS
- MAXIMISES THE EFFECTIVENESS OF APPLIANCES.
- MINIMISES THE NEED FOR MAINTENANCE REQUIREMENTS.
