Your questions about the operating principle
Yes. The operating principle has been tested and validated by independent laboratories according to recognized European standards.
The system injects a controlled amount of COâ‚‚ into the water. This converts dissolved calcium carbonate into soluble calcium bicarbonate, preventing limescale from crystallizing and sticking to surfaces.
It prevents limescale without salt, filters, or regeneration, while preserving minerals in the water and reducing maintenance and operating costs.
Correct. The system does not use salt, does not require regeneration cycles, and does not discharge wastewater.
No. The injected COâ‚‚ reacts chemically with limescale; it does not remain as free gas, so the water is not carbonated.
Yes. The water remains fully drinkable and compliant with drinking water standards. Minerals are preserved.
Most users report softer skin and hair, as limescale deposits are reduced and soaps rinse more easily.
Yes. Reduced limescale improves the effectiveness of soaps and detergents, often allowing lower consumption.
The taste may feel slightly fresher or smoother, but the mineral composition of the water remains unchanged.
The system does not remove calcium or magnesium; it keeps them dissolved in a non-scaling form, so measured hardness stays the same.
When correctly adjusted, the system keeps the water in a balanced state and does not increase corrosion risk.
The treated water remains stable when heated, significantly reducing limescale formation in boilers, heaters, and pipes.
Your questions about CO2
No. COâ‚‚ is a natural gas already present in drinking water. The quantities used are low and safe.
The system includes a pressure indicator that shows when the COâ‚‚ cylinder needs replacement.
Consumption depends on water usage and hardness, but typically one bottle lasts several months in a household installation.
COâ‚‚ costs are low, usually only a few euros per month for a standard household.
COâ‚‚ cylinders are widely available from beverage gas suppliers, installers, or specialized distributors.
Your questions about the appliance
No regular maintenance is required apart from periodically replacing the COâ‚‚ cylinder.
The appliance is covered by a manufacturer warranty, typically several years, depending on the model and market.
The correct model depends on water hardness, flow rate, and building size. An installer or advisor can determine the appropriate version.
Your questions about installation and adjustment
In normal operation, clogging does not occur. If needed, flushing according to installer guidelines is sufficient.
Adjustment is done during installation based on measured water hardness and flow, using the built-in regulation mechanism.
Installation is carried out by trained installers or plumbers authorized to work with the system.
