Water Heaters
Calmat controls scale build-up in tank-less water heaters permanently and reduces constant maintenance as heat exchangers get fewer deposits. Your water heater will work much more efficiently once again, and you can extend the time to your next service maintenance.

Heating Systems Performance
When water is heated in a hot water tank the hard water always leads to thick deposits on the heating elements. This layer inevitably causes a great reduction in the capability of the heat to transfer. With Calmat, deposits are minimized and your heating performs at a much higher capacity again. Service maintenance intervals are extended. Typically, water heating bills will be substantially reduced.

Solar Water Heating
Calmat reduces scale build-up in collectors, it protects hot water tanks and vacuum tubes and keeps the system from overheating.

For Your Health

​Mineral-rich Drinking Water
Calmat does not interfere with the natural composition of the drinking water. Important minerals remain in the water for a healthy diet. Especially young children and elderly people benefit from the healthy calcium and magnesium content that naturally is found in tap water.


Water tastes and smells better and gives food and beverages their natural flavour 
Calmat keeps the natural taste of water as it does not change its chemical composition. This gives you the best tasting water possible. Calmat cleans the piping system once again and therefore cleans it from dust particles. Rust is gone and can no longer add its unwanted flavour anymore


Kitchen Benefits

  • Kitchen surfaces, sinks, faucets and fixtures stay cleaner

  • Dishwashers operate with less detergent and fewer additives.

  • Reverse Osmosis-filters for your tap drinking water last longer.

  • You can often reduce the number of washing detergents for washing machines or stay away from very aggressive agents. Furthermore, Calmat extends the life of the machine's heating element.


Bathroom Benefits

Calmat does not alter the chemical composition of water, and calcium and magnesium remain in the water. You will quickly notice that scale is visible but acts like a fine ‘dust’ that can be removed easily with a damp cloth. Stains on basins, sinks, toilets or fixtures will be easily wiped away. Shower heads stay clean longer. Soap and detergent use can be cut back by up to 25%. The water will feel as if it is "softer" as the treatment causes a decrease in water surface tension. Generally, soap will lather up more. Skin will feel smoother and hair will be much more manageable because the scale particles no longer make it so frizzy.


Garden Benefits

Garden irrigation with sprinklers becomes more reliable as the nozzles stay free of scale. Calmat treated water can be absorbed and processed better by plants. As there are fewer scale spots on the leaves your plants take up water and rainwater better and look healthier.

Swimming Pools and Jacuzzi

Calmat makes pool cleaning much easier: the scale on the water line is looser and easier to wipe off. Pool covers and tiles on the floor or walls will show reduced hard scale stains. Calmat reduces deposits in the pipes and valves. The sensitive circulation pumps last longer, sand filters need less changing and you can cut down on chlorine tablets.

The combination of water, circulating air and pressure in a hot tub tremendously enhances scale build-up. Calmat makes the cleaning of the tub easier. Calmat reduces deposits in the pipes and valves. Covers and tiles on the floor or walls will show fewer hard scale stains.
