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?
If you’re researching limescale protection for your home, you’re probably asking one straightforward question:
How much does SoluCalc cost?
Here’s the short answer: SoluCalc pricing depends on the required flow capacity, and installation conditions. The final price includes the correctly sized system, professional installation, calibration, and initial CO₂ setup. An exact quotation is confirmed after a short technical review of your property.
Now let’s look at what that actually means.
SoluCalc is a salt-free, CO₂-based limescale treatment system installed at the main water entry point of your home. Instead of removing calcium from the water, it converts limescale into soluble bicarbonate, preventing scale buildup inside pipes, boilers, and heating systems.
Because it protects the entire plumbing network, SoluCalc is positioned as infrastructure. Not as a small add-on device.
If you want a full technical overview of how the system works, the article “What is CO2: discover the unique anti-limestone formula of SoluCalc” page explains the CO₂ conversion principle in detail.
When homeowners ask about cost, what they really want to know is whether the price is fixed or variable.
The Solucalc system itself exists in two different sizes. The correct model is selected based on the household water flow rate. During the installation the system must be calibrated accordingly. Before issuing a quotation, SoluCalc confirms which configuration is appropriate.
If you have not yet checked your local hardness level, the SoluCalc Water Hardness Calculator provides a quick starting point.
When discussing SoluCalc cost, it’s important to understand that pricing is composed of two main elements: the system itself and the installation.
The equipment price depends solely on the SoluCalc model selected for your home. Installation, however, can vary. The final investment depends on who performs the installation and where the property is located. Local labour costs, accessibility of the main water entry point, and regional market conditions can influence the installation component of the price.
A standard SoluCalc installation typically includes integration of the unit at the main water supply, calibration according to hardness and flow, commissioning of the system, and the initial CO₂ cylinder. In most residential settings, installation is completed within a single visit and does not require structural renovation.
Because installation conditions differ from one home to another, quotations reflect both the selected system model and the local installation context. This ensures that pricing remains transparent and aligned with actual technical requirements.

Yes — but they are very predictable. SoluCalc does not use salt. There are no regeneration cycles and no wastewater discharge. There is no resin that degrades over time.
The only recurring component is the CO₂ cylinder, which typically requires replacement approximately once per year for an average household, depending on water consumption and hardness levels.
Compared to salt-based softeners, this creates a different long-term cost structure.
If you are evaluating alternatives, reviewing a structured comparison between salt-based systems and SoluCalc’s CO₂ technology helps clarify the financial differences over time.
That depends on how you define cost.
Salt-based softeners may appear comparable at first glance. However, they require ongoing salt purchases, regeneration cycles, wastewater discharge, and periodic maintenance of internal components.
SoluCalc follows a different approach. It preserves natural minerals and prevents scale formation through CO₂ conversion. The relevant question is not simply “What is the upfront price?” but “What is the total cost of ownership over 10 to 15 years?” Understanding this distinction is essential when comparing systems.
When do I receive the final price?
Once you get in touch with SoluCalc, a specialist will review your property details together with you. During this short consultation, key technical elements such as water hardness, flow requirements, and installation conditions are clarified. Based on this discussion, you will then receive a quote that reflects both the selected SoluCalc model and the specific installation context of your home.
This approach ensures that the proposed price is aligned with your actual technical requirements rather than based on assumptions.
Are there hidden maintenance costs?
No. The only recurring cost is periodic CO₂ cylinder replacement. There are no salt refills, no regeneration wastewater, and no resin replacement.
How long does installation take?
Installation is usually completed within 1-2 hours during a single visit.
