How Does a Water Descaler Work

The salt-free water descalers don’t soften water but they realign the ions. This is normally done by a magnet or a cartridge that’s featured in the device. What the magnet does is that it makes the water ions want to repel against each other. This, in turn, prevents them from building up in the sinks and the facets.

An electronic water descaler doesn’t get rid of these minerals from your water. All it does is to prevent limescale build-up. The descaler also gets rid of all the harmful substances. This includes chlorine that would be harmful to your skin and hair.( source

With a vented water system, you can install the descaler wherever your cold mains are fitted. Note that it’s also quite essential to install it on the cold down service to the hot cylinder. This is to ensure that scale doesn’t build up on the immersion element which may breakdown as a result.
