The best water damage is the kind that never happens.

Why clean heating water is the best protection against leaks.

Many people think that water damage only occurs as a result of sudden pipe bursts.
A bang, a crack, a flood—that’s the image in our minds.

But the truth is different:
Most leaks develop gradually. Not because of a workmanship error.
But because the heating water itself attacks the system from the inside.

And that is precisely where the key to prevention lies:
Clean, chemically stable heating water prevents damage – before it occurs.

Heating water is not a filler. It is a building material.

Imagine:
You fill a brand-new system with untreated water. It works. The customer is happy. Everything is fine.
For now.

But from day one, a silent process begins in the system:

• Oxygen reacts with metal → Corrosion
• Hardness formers settle → Lime + deposits
• Conductivity increases → Material stress

And then…
a hole eventually forms.

A pinhead-sized corrosion spot.
But that’s enough: drop by drop over weeks → damage that will be expensive.

Not suddenly. But steadily.

The good news: you can prevent this.

If the heating water is corrosion-inhibiting, low in salt, and pH-stable,
the system has no reason to attack the material.

And this is where our UWS products come in:

Heaty Ferriline No. 2 – Protection begins with cleaning

In a bypass process, the mobile treatment device removes:

• Magnetite
• Rust particles
• Dirt from installation and inventory

Less solid matter → less wear → fewer weak points in the pipes. And thanks to Vadion pH Control, the pH value is always within the correct range.

Heaty Complete series – Refilling heating water in accordance with guidelines

Once you have adjusted the heating water to be clean and in accordance with the recognized rules of technology according to VDI 2035, you certainly don’t want to lose these perfect values the first time you top up.

That’s exactly what the Heaty Complete series. In combination with our Vadion pH-Control mixed bed resin, only water that has been treated in accordance with guidelines enters the system.
Low in salt, pH-stable, corrosion-inhibiting – with every single top-up.

This not only keeps the system clean today. But every day that it runs.

And if there is ever a small leak somewhere, the built-in leak protection in the Heaty Complete PROfessional detects it and immediately sounds the alarm.

Heaty Complete Professional

Heaty Complete PROfessional is the world’s first smart IoT make-up system, including Cloud connection – fully automatic, leakage protection and digital water meter.

MAGella magnetite separator – no more clogged bottlenecks

Magnetite sludge is a real system brake.
It creeps into every narrow space:
into valves, control elements, pump impellers, and heat exchanger channels.

The result:

• Control valves jam
• Pumps start to falter
• Flow rates drop
• The system loses performance — long before any real damage becomes visible

With the MAGella magnetic separator, you can remove this “system congestion” during operation or prevent it from occurring in the first place.
This keeps the water flowing freely — and allows the technology to do what you installed it for: distribute energy efficiently.

MAGella MG 200

The MAGella MG 200 magnetite and sludge separator mounted on the return pipe of the boiler protects the system from all types of contamination.

Why prevention is always cheaper than repair

No operator in the world celebrates emergency drainage of the screed. But everyone is happy about a system that works longer than promised.

Conclusion

What is filled cleverly remains tight. It is not the strongest pipe connection that ensures safety, but the chemically stable water that flows through it.

Corrosion-inhibiting, treated heating water is the best protection against leaks.
It saves money, nerves, and damage—and secures your reputation as a professional:

“Müller’s systems run. Always.”
