Carefree heating: Why the right heating water quality is crucial for long-lasting systems

A modern heating system should do one thing above all else:
run reliably, efficiently, and without problems—for many years to come.

In practice, one factor that has long been underestimated often plays a decisive role:
the quality of the heating water.

Even the best technology cannot reach its full potential if the heating water is not suitable.
The right heating water quality is therefore not a minor issue – it is the basis for trouble-free system operation.

Heating water quality: the silent success factor in the background

At first glance, heating water always looks the same.
But chemically speaking, it can vary significantly—sometimes with serious consequences for the system.

Among other things, the following are decisive:

• the pH value
• the conductivity
• the content of dissolved salts
• Oxygen ingress

If these parameters are not matched to the respective system, the risk of the following increases:

• Corrosion
• Scale formation
• Magnetite deposits
• Losses in efficiency

All of this often happens gradually – and goes unnoticed for a long time.

Damage does not occur suddenly – but systematically

At first glance, many types of system damage appear to be a surprising defect.
In fact ,they are often the result of a long-term chemical imbalance in the water.

Typical causes:

• Filling with unsuitable tap water without treatment
• Lack of or insufficient treatment
• Uncontrolled replenishment
• No regular checking of water values

The problem with this:
Once the damage is visible, the causes are often months or years old.

The right heating water quality ensures safety

Those who ensure suitable heating water quality from the outset significantly reduce risks.
Treated heating water ensures that:

• Corrosion processes are minimized
• different materials harmonize better with each other
• Deposits and sludge are avoided
• Heat generation efficiency is maintained

In short:
The system runs more stably – and is easier to plan.

This not only creates technical safety, but also mental relief for operators and specialist companies.

Guidelines and standards provide orientation – but they are no substitute for a concept

Regulations such as VDI 2035 define clear requirements for heating water.
They provide an important basis – but are not a sure-fire success.

It is not only crucial to comply with limit values, but also to:

• to ensure water quality in the long term
• identifying changes at an early stage
• Controlling make-up water

Only then can a sustainable water concept be created that truly safeguards plant operation.

Mischbettharz Vadion pH Control

Our Vadion pH-Control is a mixed bed resin that not only desalinates the water to < 100 μS/cm (equivalent to 0-2 °fh) but also ensures that the pH value of the filling water is within the required range.

Make-up water: the critical point in everyday life

A particularly sensitive moment for heating water quality is when water is added.
Every liter of untreated water can:

• increase conductivity
• shift the pH value
• introduce new corrosion risks into the system

If make-up water is not integrated into a clear treatment concept, the water quality originally achieved will gradually be lost.

Operation only becomes worry-free when this point is also consistently taken into account.

Heating water quality is a responsibility – not an option

Like all solutions from UWS Technologie, our concepts are based on a holistic approach.
Heating water treatment does not end with commissioning – it accompanies the system throughout its entire service life.

This means:

• measuring instead of guessing
• documenting instead of discussing
• preventing instead of repairing

This makes heating water quality an active component of professional plant technology.

Worry-free does not mean maintenance-free – but controlled

Worry-free heating does not happen by chance.
It is the result of a clean interplay between:

• correct heating water quality
• appropriate treatment
• regular monitoring

Those who take this factor seriously benefit from:

• longer-lasting systems
• fewer malfunctions
• clear responsibilities
• Satisfied operators

The right heating water quality is not a minor detail—it is the basis for long-term, safe system operation.
