The descaler should be space-saving and lightweight for convenience.

How Does a Water Descaler Work?

Well, let’s see how water descalers work in case you are using them for the first time.

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 prevent limescale buildup. The descaler also gets rid of all the harmful substances. This includes chlorine that would be harmful to your skin and hair

How to Install?

Now that you know why you need a water descaler. It’s time we enlighten you on how to go about the installation. First of all, you will need to determine whether your home has a vented or an unvented water system.

A vented water system has a cold water storage tank placed in the loft on top of the ventilation closet. But, an unvented water system doesn’t have a water tank.

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 break down as a result. If your home is 5 bedrooms, you will need to fix a single LP2 on the mains and one LP1 on the cold-down facility.

If you have an unvented system, all that matters is that it should be done on the cold mains pipe. This is because the descaling magnet releases currents in all directions. With this, the water flow direction isn’t a problem.
