In heating water treatment, there’s a lot of talk about standards.
About guidelines, limit values, and minimum requirements. All of these are important—no question.

But at UWS, we’ve always asked ourselves a different, crucial question:
What does the system really need—today, tomorrow, and throughout its entire service life?

It was precisely this requirement that led to the development of the Heaty Complete PROfessional.
Not as a traditional filling solution, but as a permanently integrated makeup system that adapts to actual system operation.

More than just compliance with VDI 2035

The requirements of VDI 2035 represent the state of the art today.
But anyone who regularly operates or maintains large or sensitive systems knows:

Starting out in compliance with guidelines does not automatically mean remaining operationally safe in the long term.

The biggest challenge often begins after commissioning —with makeup water.
Because every water replenishment alters the water chemistry and thus the stability of the entire system.

This is exactly where the Heaty Complete PROfessional comes in.
It ensures that every water make-up is automatically treated, monitored, and controlled — and that the water quality, once achieved, is maintained over the long term.

The result:

  • Permanently reduced corrosion risks
  • Minimized scale and magnetite formation
  • Stable water parameters throughout the entire system lifespan

To the product

PROfessional means: monitor, detect, intervene

A key difference from traditional solutions lies in monitoring.
The Heaty Complete PROfessional doesn’t just think along with you — it reacts.

In the event of unusually high water demand, for example due to:

  • creeping leaks
  • defective components
  • unnoticed system losses

the system issues a warning and automatically interrupts the makeup feed.
This reliably prevents uncontrolled refilling, unnecessary water consumption, and potential water damage.

This protects not only the heating system, but also:

  • the building
  • the operator
  • the service provider

For systems where operational safety matters

The Heaty Complete PROfessional is particularly suitable for applications where makeup water must be managed in a predictable, safe, and sustainable manner, for example in:

  • multi-family residential buildings
  • Commercial and functional buildings
  • Larger residential complexes
  • Complex heating and cooling systems

Anywhere where unplanned interventions and subsequent damage are not an option.

Prevention instead of repair

A core principle at UWS is:
Prevent problems before they arise.

The Heaty Complete PROfessional is therefore not a repair tool, but a preventive system.
It helps prevent typical causes of damage from occurring in the first place—such as:

  • repeated top-ups with unsuitable water
  • gradual increases in conductivity
  • unnoticed pH shifts
  • uncontrolled water volumes in the system

Combined with regular water analysis, heating water treatment thus becomes a continuously controlled process —not a one-time mandatory task.

A system for professionals – clear, robust, and transparent

Like all solutions from UWS Technologie, the Heaty Complete PROfessional is consistently designed for everyday use in the HVAC trade:

  • robust, durable components
  • clear system logic
  • transparent processes
  • clear documentation for operators and clients

No unnecessary complexity—just technology that continues to function reliably even after years of use.

To the product

PROfessional is not a product feature. It is an attitude.

With the Heaty Complete PROfessional, “PROfessional” doesn’t mean more complicated or technical.
But rather for forward-thinking, practical, and permanently safe.

For everyone who doesn’t view heating water treatment as a mere formality, but as a crucial component for long-lasting, efficient, and damage-free systems.
