Keep the softener, broaden the approach
When softening remains useful for domestic hot water production, MEDIAGON can be considered as a complement, particularly for uses and networks not served by the softener.

Limescale treatment for cold water and hot water throughout your building.
Shared boiler rooms, domestic hot water tanks, plate heat exchangers and solar thermal systems: consider MEDIAGON across your building, without salt or regeneration.
Alongside a water softener or as a standalone limescale solution, depending on your boiler room.

ALREADY EQUIPPED WITH A WATER SOFTENER?
The hot water is softened.
What about the cold water?
When the softener only supplies domestic hot water production, the cold water distributed to apartments remains unsoftened.
COLD WATER
An unsoftened branch
It retains its hardness before reaching the tap.
DOMESTIC HOT WATER
A softened branch
The softener treats the water feeding domestic hot water production.
AT THE MIXER TAP
The two waters mix
The cold water portion still contains calcium and magnesium. Deposits may therefore remain at points of use.
An example configuration, not a general rule or an installation diagram. Treatment coverage depends on your building’s connections.
Complement the existing system or choose a standalone limescale solution.
The project does not start by removing your equipment: it starts by understanding your boiler room.
Assess MEDIAGON across the building
A standalone MEDIAGON configuration can be considered when the equipment does not require hardness reduction. Locations and the number of devices are determined according to the networks.
MEDIAGON does not reduce hardness. When used alongside it, the retained softener continues to operate; its salt use and regeneration cycles do not automatically disappear.

The entire boiler room
is part of the assessment.
Domestic hot water tanks, plate heat exchangers, solar thermal systems and distribution: equipment is assessed together with the networks that supply it.
Cold water distribution
Main inlet, risers and branches: include uses that do not pass through hot water production.
Domestic hot water tanks
Identify the supply, storage, heat-transfer surfaces and recirculation loop. The scope covers domestic water and areas exposed to deposits.
Plate heat exchangers
Distinguish the two circuits, the fluid and the side affected by scaling to determine useful installation points.
Solar thermal systems
Consider domestic hot water production supplied by solar energy and the heat-transfer surfaces in contact with domestic water.
The primary heating circuit and the solar heat-transfer circuit remain separate from domestic water. Installing MEDIAGON on one network does not automatically validate treatment of another circuit. Equipment maintenance and water-hygiene monitoring instructions must still be followed.
Understand installation around the pipeMAINTENANCE · WATER · BUILDING CHARGES
The cost of limescale goes beyond descaling.
A scaled plate heat exchanger or tank may require a service intervention, products and rinsing. For your building, let us examine every cost item, including cleaning-water management and organisation of the hot water service.
Service interventions
Descaling frequency, heating contractor services, labour and any parts replaced.
Water and discharges
Rinsing volumes, products used and the planned route for managing cleaning water.
Service to residents
Duration of the intervention, hot water availability and arrangements for returning the system to service.
THE MEDIAGON PROJECT
Limit descaling associated with limescale.
The assessment aims to determine how MEDIAGON’s limescale action could limit chemical descaling on the selected networks, while retaining the necessary boiler room maintenance.
Alongside the existing softener or as a standalone limescale solution: the configuration is defined across your building.
Products and cleaning water: what should be planned?
Some descalers use acids and may require neutralisation. Their selection, handling and disposal are organised according to the safety data sheet, manufacturer instructions and rules applicable to the building.
Neutralisation alone does not establish that a discharge is authorised. Cleaning frequency depends on the equipment’s condition and maintenance plan: this is not a general requirement for annual chemical descaling.
The Brussels Environment guidance is a regional example. The building’s location and discharge route determine which rules must be checked.

PURCHASE · HIRE PURCHASE · RENTAL ONLY
Install for the long term.
Or take targeted action.
For your building, CO2H2O offers purchase, hire purchase or rental only for targeted action on existing limescale deposits.
LONG-TERM INSTALLATION
Equip your building for the long term
Through purchase or hire purchase, plan a limescale treatment installation suited to the selected equipment and networks.
The option is chosen with the co-owners, according to the agreed scope and project budget.
Explore purchase or hire purchaseTEMPORARY RENTAL · ACTION ON EXISTING DEPOSITS
Rent to address existing deposits
Rental only can be offered to support pipe cleaning through MEDIAGON’s physical action, without the process adding a descaling product.
We define the network concerned, the rental period, observations and necessary follow-up operations.
Explore rental for existing depositsYour proposal specifies the equipment, installation, duration, monitoring, any rinsing, price and end-of-contract arrangements. Action on deposits is gradual; the outcome and timescale depend on the installation.
Device warranty: 10 years. Coverage terms are specified in the CO2H2O offer.
What happens after a rental for existing deposits?
A one-off intervention and long-term limescale protection have different objectives. The next steps are agreed with you; temporary rental does not promise permanent protection after the device is removed.

YOUR QUESTIONS
Before you start.
Does the existing softener have to be removed?
Not necessarily. MEDIAGON can be considered alongside it or as a standalone limescale solution, according to the networks and equipment requirements. Hardness reduction and limescale control do not have the same objective.
Can I rent only for action on existing deposits?
Yes. CO2H2O also offers rental only for targeted action on existing limescale deposits, without the process adding a descaling product. Scope, duration and follow-up are specified in the proposal.
View the optionsAre hot water tanks and solar thermal systems included?
Yes, they are among the equipment to be assessed. Domestic water must be distinguished from the primary and heat-transfer circuits to identify the heat exchanger side and pipes concerned.
What about maintenance and water-hygiene monitoring?
Limescale treatment does not replace tank and heat exchanger maintenance or the water-hygiene monitoring planned for the building. Objectives and follow-up operations are identified during the assessment.
PREPARING THE DISCUSSION

without measuring everything.
An overview of the boiler room and photographs of the current treatment, tank and connections are enough to start the discussion.
