CalMag is a magnetic scale inhibitor. It contains a magnetic bar to induce a single polarity into the water. This causes the calcium and magnesium (limescale) particles to take on the same polarity. The particles then repel each other, and as a result prevent the formation of hard limescale.

CalMag can be fitted onto the hot or cold water lines. The unit is also available to fit 15mm and 22mm pipework. It comes with compression fittings as standard and does not require earth bonding. Once the unit has been installed you can sit back and relax as it will continue to work day and night without the need for regular maintenance.

CalMag comes with a lifetime guarantee on parts. For more details please click here .

After Installation you should notice the following effects…

1. Any hard limescale that has formed around taps, sinks etc, will begin to soften with regular contact with treated water. This will make it much easier to clean.

2. Shower heads will be become descaled over time. Initially, showerheads may become blocked with loose limescale debris (often the case with electric showers). To solve this, simply remove the shower head and rinse out the debris.

3. After several months your hot water system will gradually become more efficient. Eventually you should be able to lower the water temperature and make considerable savings over the year. For more information on how limescale can affect the efficiency of your heating system please click here.

IMPORTANT NOTE…
CalMag will not keep your kettle scale free. All scale inhibitors rely on water flow to prevent hard limescale formation. Since there is no water flow in a kettle, soft limescale will still form. In order to prevent limescale build up in your kettle, Calmag recommend the use of the following products; CalSlim R  and CalFresh CR.
