MEDIAGON or CO₂ treatment?
Salt-free,
without refills.

CO₂ limescale treatment means considering the injection system and its gas supply. MEDIAGON offers a different kind of simplicity: external fitting, no refills and no electrical socket.

No saltNo gas to replenishNo injection
Illustration of the two approaches. Compare purchase budgets using quotes with the same scope.

The purchase price matters.
So do the refills.

Comparing a CO₂ injection limescale treatment quote, such as SoluCalc, with MEDIAGON? Look at the complete installation cost : equipment, fitting, accessories and commissioning. The budget is not limited to the unit in the photograph.

The cylinder and accessories of a CO₂ system can increase the initial budget. Gas replenishment comes on top. With MEDIAGON, this refill cost is absent: the quote focuses on the device suited to your pipe and its fitting.

Compare the purchase, then the years ahead.
Two comparable quotes show the actual initial difference. Refills then let you assess a cost that MEDIAGON does not add to everyday use.

A MEDIAGON quote is not declared cheaper than every CO₂ system. The amount depends on the model, services and VAT; the illustration is not a universal price list.

Two salt-free approaches.
Different requirements.

Both processes retain the minerals. What distinguishes MEDIAGON here is operation without a consumable added to the water, and fitting around the pipe.

Comparison of fitting and use, not a performance ranking.

Gas budget€0 in CO₂ refills.This cost is not part of MEDIAGON operation.A recurring cost.Gas and any services are added to the investment.
Regeneration waterNo resin regeneration.No brine from MEDIAGON operation.No resin regeneration.This is also true of the CO₂ treatment considered: do not attribute brine savings to one over the other.

CO₂ configuration and monitoring vary by manufacturer and model. Both approaches retain minerals; hardness alone is not a measure of deposits.

Less logistics.
More simplicity.

Refills leave your to-do list. With MEDIAGON, no gas cylinder to exchange or CO₂ delivery to arrange. One less cost and task to manage.

Your pipe stays in place. The device fits around the pipe without an injection point. Material, diameter and available space guide model selection.

No gas dosage to monitor. MEDIAGON injects no gas and depends on no reserve. A simple device does not replace maintenance of building equipment.

Your CO₂ consumption and budget

Hardness alone cannot determine an exact dose. Estimate gas mass and cost using an identified reference, your water consumption and refill price.

Gas only, excluding the initial cylinder deposit. Change 10 kg if your cylinder has a different capacity.

SoluCalc average: 10 kg / 100 m³ (2021 publication). Hardness is recorded as context but does not change this average; no exact dose is inferred.

Difference not calculated: complete both quotes and fitting, then confirm comparable scope.

Provision proportional to gas used, not a purchase schedule: remaining gas carries over. Constant prices; no inflation, performance or heating savings calculated. Excludes unentered deposits/rental, electricity, maintenance and repairs; delivery/replacement only if included in your price. Avoid double-counting an initial cylinder included in a quote: deduct its gas value from the quote before comparing these subtotals.

Targeting limescale.
Without injecting a product.

MEDIAGON uses an external physical approach. It targets adherent deposits and gradual breakdown of existing scale, without removing minerals or adding salt or gas to the water.

The time and extent depend on the network and its use. Water may still leave marks after evaporation, and routine maintenance remains necessary.

A couple arrives late at a friend's dinner after trouble with a scaled shower head. Their friend shares MEDIAGON. They have a device fitted and thank her. She receives a gourmet gift when referral conditions are met. This is illustrated fiction, not a performance measurement.
