Would you like a quote for the installation of a SoluCalc, more information, or personalized advice? Do you have a question, a technical issue, need assistance, or want to replace your CO₂ cylinder? Are you convinced by our alternative to salt-based water softeners and would like to become a partner or certified installer?
In Belgium, limescale in water is a widespread reality. This affects both single-family homes and apartment buildings or residential complexes. Over time, the resulting limescale deposits damage boilers, water heaters, heat exchangers, pipes, and household appliances.
The issue with limescale is therefore not its existence, but its scale and the way it forms. SoluCalc offers a CO₂-based technology suitable for both single-family homes and collective residential buildings, specifically sized according to the type of infrastructure.
In a single-family home, limescale treatment primarily serves to protect the entire domestic installation. The unit is installed on the main water inlet of the building, before internal distribution. This way, hard water is treated throughout the entire system: bathroom, kitchen, boiler, water heater, and household appliances.
SoluCalc technology is based on the controlled introduction of food-grade CO₂ into the water. This reaction transforms limescale into soluble bicarbonate. This means that calcium remains present in the water but no longer settles as solid scale on surfaces. The objective is not to chemically soften the water, but to prevent limescale from adhering to installations.
In a residential context, integration is generally simple and compact. The solution is designed to adapt to standard household consumption without changing occupants’ habits or requiring heavy infrastructure.
Advantages in a single-family home • No salt • No regeneration wastewater discharge • Limited maintenance • Preservation of the water’s natural mineral content • Compatible with all existing installations
In an apartment building or collective residence, technical challenges are more complex. Water volumes are higher, consumption is continuous, and technical installations (such as central boilers or heat exchangers) represent a significant investment. Limescale treatment therefore becomes a structural and economic issue.
SoluCalc is installed on the building’s main water inlet, upstream of the central technical installations. The size of the SoluCalc unit is selected according to flow rate, pressure, and the number of housing units. The objective is to protect the entire collective network and common installations while ensuring consistent efficiency for all occupants.
SoluCalc also provides a solution to limit limescale deposits in central hot water systems and technical circuits. This helps reduce overall maintenance costs, repeated technical interventions, and energy losses caused by scale buildup.
Advantages in a collective building • Reduced maintenance costs • Protection of boilers and heat exchangers • Fewer technical interventions related to scale • Centralized solution for all occupants • Alternative to salt-based systems on a large scale
SoluCalc technology is identical in both cases. What changes is the field of application and the degree of technical integration.
In a single-family home, the focus is on maintaining daily comfort and ensuring proper functioning of household appliances. The network is generally simpler, flow rates are moderate, and consumption varies depending on occupants’ usage.
In a collective building, the logic is different. The goal is to protect a shared infrastructure that operates continuously. Water volumes are significant, and centralized technical installations can generate considerable costs in the event of malfunction or excessive scale buildup. The solution must therefore be precisely dimensioned and integrated into a structured technical environment, such as a boiler room or dedicated technical space.
The choice between residential and multi-residential does not concern the technology itself, but its adaptation to the building’s configuration and usage.
Choosing a salt-free solution is based on sustainability and simplicity. Unlike traditional water softening systems, CO₂ technology requires no salt storage, no regeneration cycles, and no additional water discharge. It acts directly on the behavior of limescale in water.
In a residential building, SoluCalc is a discreet and easy-to-install system that is fully compatible with the natural operation of the domestic water network. In a collective building, installing SoluCalc eliminates large-scale salt logistics and the associated technical constraints.
Cross-cutting advantages • No handling or storage of salt • No regeneration wastewater discharge • Preservation of natural minerals in the water • Scalable and adaptable installation • Reduced long-term operational constraints
Conclusion
Whether for a single-family home or a collective residential building, limescale treatment must be adapted to the structure of the building and its water consumption volume. SoluCalc offers a modular solution, dimensioned according to usage, while maintaining a coherent and sustainable approach.
