CalGlow is a totally unique scale inhibitor that combines two scale inhibiting technologies into one. The first technology is the use of 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. The second technology is the use of zinc plates which create the same reaction as the magnet. Once water passes over the plates and the inner copper body of the unit, a single polarity is induced into the water supply. This then stops the formation of hard limescale. In addition, the zinc plates slowly release minute particles into the water supply which prevents corrosion by removing all the air in the system.

CalGlow can be fitted in two places. The first is on a central heating system to stop corrosion and the second is on hot or cold lines to prevent the formation of hard limescale.

CalGlow can be fitted to 22mm pipework and does not require earth bonding. The unit also comes with compression fittings. 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.

CalGlow comes with a lifetime guarantee on parts.
