calmat® benefits

Piping System

Reduction of scale deposits in your piping system

calmat® takes away the adhesive power of scale particles so that scale is simply washed away with your water as a fine powder. New scale-formation is stopped.

calmat® dismantles already existing deposits

calmat® carefully dissolves already existing deposits in the piping system. The scale build-up process is reversed and the pipes gradually become clean again. This take-out process will not block up your pipes or drain because the treated crystals are microscopic in size and wash away in the water.

Corrosion protection

Metal pipes often suffer from pitting corrosion. The electric calmat® impulses generate a metal-carbonate protective layer that prevents pitting corrosion.

Increased water pressure

calmat® sanitizes the pipes from scale deposits and can even restore a pipe’s full diameter. Water can flow freely again and you regain normal water pressure.

calmat® minimizes rust

In most cases whenever there are scale deposits you will find rust shortly thereafter. The rust typically imbeds itself in the scale deposits. Because rust oxides are red, the scale deposits in metal pipes then often appear red in color, too. When the calmat®-treatment reduces scale, it also takes away rust with it.

calmat® minimizes bacterial growth in pipes

Thick scale deposits with their uneven surfaces are the perfect breeding ground for bacteria. Once the scale is gone, there are no more nesting areas where bacteria can grow.


Water heaters

calmat® controls scale build-up in tankless 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 regain full 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® prevents scale build-up in the system. It keeps heat exchangers and distributor pipes clean. Furthermore, calmat® reduces scale build-up in collectors, it protects hot water tanks and vacuum tubes, and keeps the system from over-heating. There is no more need to circulate acids.

Kitchens and Kitchen Appliances

Kitchen surfaces, sinks, faucets and fixtures stay cleaner

You will quickly notice that scale is visible but acts like a fine ‘dust’ which can be removed easily with a damp cloth. Surfaces and tiles will be smoother and shinier again.


Dishwashers operate with less detergent and less additives. The use of detergent can be reduced by up to 25%. Typical spotting on dishware is reduced or no longer apparent.

Reverse Osmosis filters

RO-filters for your tap drinking water last longer. Water filters and RO-filter membranes will work more efficiently and the permeate is easier to handle.

Bathrooms and Well-Being

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’ which 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.

Washing Machines

Cleaning is more effective as calmat®-treated water lathers noticeably more. The same amount of detergent will give you cleaner clothes. You can often reduce the amount of washing detergents in your daily use or stay away from very aggressive agents. Furthermore, calmat® extends the life of the machine’s heating element.

Private Swimming Pools

calmat® makes pool cleaning much easier: scale on the water line is looser and easier to wipe off. Pool covers and tiles on the floor or walls will show less hard scale stains. calmat® reduces deposits in the pipes and valves. The sensitive circulation pumps last longer, sand filter 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 and tiles on the floor or walls will show less hard scale stains.

Gardening and Irrigation

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

Health issues

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 its natural flavor

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 rust particles. Rust is gone and can no longer add its unwanted flavor any more.
