There are four types of hard water treatment options, depending on Best Water Distillers. Each treatment method can reduce, inhibit or eliminate limescale. Here's a quick overview of how each of these four categories works, their strengths and weaknesses, and how they are done.

1. Physical Water Conditioners

Physical water conditioners are known for their ability to physically alter the properties and reduce or eliminate limescale formation. There are three types: electrolytic, magnetic and electronic.

1a. Electronic water conditioners also known as electrodescalers or limescale inhibitors, usually consist of a small box with electronics and one to three coils wrapped around the pipework.

What they do. Electronic conditioners transmit an audio frequency or radio frequency signal through water pipes using induction coils. This reduces limescale buildup inside the water pipes, and over time, also reduces existing scale. While softer scales may form on taps and shower heads, it is much easier for them to be cleaned.

Benefits: These descalers can be very cost-effective and are cheaper than other hard water treatment methods. These descalers are easy to install as they do not require any plumbing. The water does not contain any chemicals, so it is safe to drink.


1b) These are inline devices which need to be plumbed into your water system. To fit the pipework, they can be purchased with either 15mm, 22mm, and 28mm end connectors.

What do they do? Two dissimilar metals are found inside an electrolytic conditioner. Normally, copper and zinc act both as a cathode or anode. The electrolytic current flowing from the anode cathode into the anode causes small amounts to dissolve in the water. The positively charged scale is disrupted by the metalions. They form particles which don't clump together, and thus create scale.
