Common questions

Answers

How do the Mediagon devices work?
Mediagon devices work due to their patented metallurgical technology (manufacturing, pressing and hardening processes), environmentally friendly without chemicals, electricity or magnets.
Can I test Mediagon for free?
Yes, in Switzerland EFH owners benefit from a 6-week free trial. When installation is performed by Mediagon professionals, you also receive a free pipe flush. We are happy to visit and install the appropriate device for you.
What is the difference between Mediagon devices and desalination systems?
Unlike chemical water softeners, Mediagon uses no chemicals, no salt, and no magnets. Unlike ion exchange systems, Mediagon devices do not remove valuable minerals such as calcium and magnesium from drinking water.
What costs are incurred for maintenance and service?
None, the Mediagon devices are completely maintenance-free and operate for decades.
Is the effectiveness of the technology proven?
Yes, the Mediagon technology and the effectiveness of limescale protection have been tested, inspected, and confirmed by TÜV Germany.
How do Mediagon devices promote vitality and protect household appliances?
Vital vitamins, calcium, and magnesium remain in the water. In addition, no water pipe needs to be cut. The water stays vital, stable, and healthy – completely without chemistry. No limescale or rust forms in the pipes.
Which device fits my house, my apartment, my business?
There are four models: Type D and Type Z for single-family and two-family houses, Type I for industrial operations and Type P for gastronomy, agriculture, hospitals and homes.
Why is the Mediagon Kalkschutzanlage suitable for your single-family home (EFH) or 2-family house (2FH)?
For single-family homes (EFH) and 2-family houses (2FH), Mediagon Kalkschutzanlagen Type D and Type Z are particularly suitable. Both models are intended for private households and can be installed space-saving in existing water pipes.
Is the water pipe cut open for installation and are maintenance costs incurred?
No. Mediagon convinces with simple, dust-free installation – without cutting the water pipe. The installation takes only a few minutes. A major advantage is that there are no maintenance costs, and you also receive a 20-year guarantee.

How do household appliances stay protected from limescale?

From our experience with Mediagon limescale protection: what matters is not just a single device, but the whole household. When limescale deposits in water pipes and at taps decrease, kettles, coffee machines and daily cleaning all benefit.
