Crash course in heating water treatment

Imagine a newly installed heating system. Everything is sparkling, the display lights up reassuringly, and the customer nods with satisfaction. You leave the boiler room feeling good—and deservedly so, because you’ve done a clean job.

But six months later, that same customer calls: “
The system is running constantly… , but the living room is still cold.”

Suddenly, you have this nagging feeling in the pit of your stomach. You know that when a system behaves like this, something is wrong with the system. And most of the time, this “something” is invisible in the heating water. Not in the boiler. Not in the heat pump. But in the medium that does all the work.

Heating water — the lifeblood of the system

We’re not talking about just any liquid. We’re talking about the most important energy source in the building.

And as with humans, if the blood is contaminated, the organs begin to suffer.

In heating, this means:

• Magnetic sludge clogs valves
• Limescale clogs heat exchangers
• Corrosion eats through pipes
• Pumps struggle against dirt instead of transporting heat

And then a plant engineer stands in the boiler room and asks himself: “Why isn’t this thing working the way it should?”

The reality on construction sites: time pressure vs. water quality

You know it all too well:
Technical rooms are getting smaller and smaller, time windows shorter and shorter, and requirements greater and greater.
And then someone says:
“Please fill the system quickly today,” and then the hose is usually connected — and bang, water in.

And that’s how the later malfunction begins.

The smart solution:
👉 Quickly fill with drinking water — and then treat it directly in the bypass.

This allows you to start without wasting any time — and still have clean heating water.

UWS makes it particularly easy for you:
Simply connect treatment devices such as the Heaty Ferriline No. 2 via bypass —
and the renovation can begin during ongoing operation.
No downtime. No drama.

What makes good heating water?

Good heating water is chemically stable. It does not stress the materials. It transports heat instead of problems.

Three things must be right for this:

1️⃣ Low conductivity: no aggressive salt party
2️⃣ Stable pH value: every metal in the system feels comfortable
3️⃣ Minimal residual hardness: no limescale in the heat exchanger

If these values are within the green range according to the recognized rules of technology in accordance with VDI 2035 → the system remains healthy.

But what if the system is already unhealthy?

Then you need a “rehabilitation program”.

➡️ Heaty Ferriline No. 2 frees the system in the bypass from the sludge that moves through the pipes or has already partially settled.
➡️ The MAGella magnetite separator remove the black particles from the circuit before they cause damage.
➡️ And if you really need to clean thoroughly: Heaty Filtra Advanced filters down to 1 µm — you’ll notice the difference immediately when it’s running.

It feels like you’re giving the system a fresh blood transfusion. And the heat generators will thank you with every reduced cycle.

The moment of truth: replenishment

The monster in the boiler room is not called “hydraulics”.
Not “control”.
No “hydraulic balancing”.

It’s called:
“Refilling without thinking.”

Once you let tap water in, even though the system was perfectly stable — you’re back to square one.

Therefore:
➡️ Heaty Complete PROfessional
Provides pH-stabilized, low-salt heating water into the system.
This keeps the water chemistry stable — even after years.

How it works for you as a specialist company

With this knowledge, you are like a kind of system therapist.
You prevent problems instead of chasing after them. You save costs—and nerves.

And above all:
You’re there when the system is still running like new after years — and the customer says: “It’s good that YOU did it that way back then.”

That’s appreciation. That’s expertise. That’s your reputation.

Conclusion

If you ignore heating water, you ignore the basis of every heating system.
If you control it, you control efficiency.
Comfort.
Durability.
The success of your work.

Fill quickly. Process directly in the bypass. And think about quality every time you top up.

And you’ll see:
Heating systems can be really grateful. 🔥💧
