More than just convenience—a real contribution to efficiency, safety, and standard-compliant operation

“Fully automatic replenishment” – sounds practical. But what exactly does it mean? And what distinguishes a truly smart solution from a simple refill valve?

For HVAC professionals, the answer is clear: it’s no longer just about refilling, but about precise pressure control, leak protection, energy efficiency, and complete documentation of heating operation.

This is exactly where Heaty Complete PROfessional comes in. It shows what fully automatic replenishment must be capable of today – and why it saves so much time, effort, and risk in the everyday work of HVAC companies.

The difference: automatic does not equal intelligent

Many refill units only react to pressure drops – they open the water supply, refill, and close again. Sounds simple, but it is also prone to unnoticed replenishment.

For example, if there is a leak or a heat exchanger is slowly dripping, it will often be refilled silently over days or weeks – until the heating system literally “drowns.” . The problem: operators usually don’t notice this until the damage is extensive.

A fully automatic make-up water system such as the Heaty Complete PROfessional does things differently: it thinks for itself and actively protects against water damage, pressure loss, and unnecessary filling water – through clear limit values, seamless monitoring, and targeted communication.

Three parameters, full control: How Heaty Complete PROfessional works

Heaty Complete PROfessional monitors three critical parameters simultaneously – around the clock:

  1. System pressure
  2. Replenishment quantity
  3. Replenishment frequency or time intervals

If even one of these values is exceeded, the system immediately stops the make-up process. At the same time, a warning message is sent directly to the HVAC company or the operator – without the need for an additional app or LAN connection. This turns replenishment into a proactive safety feature:
→ No unnoticed water loss. No expensive building damage. No pressure problem.

The advantage for you as a specialist company: You are notified immediatelyif something is wrong with the system—and can react in good time before the customer even notices that there is a problem.

IoT included: The cloud thinks for itself

Another key element: the integrated eSIM connects the device fully automatically to the UWS Master Cloud – independently of the local network or Wi-Fi. Even in the basement.

The UWS cloud portal enables you to:

  • Live monitoring of all make up processes
  • Access to device status, cartridge level, and history
  • Documentation for VDI 2035-compliantoperational management
  • Legally compliant protocols in the event of damage
  • Planned maintenance based on real values instead of gut feeling

This means: No more manual checks on site, no additions to the operating documentation – Heaty Complete PROfessional provides you with everything at the touch of a button.

Why all this is not just convenience – it also brings real energy and operational reliability

Replenishment is more than just adding water. When implemented correctly, it can:

  • Protect pumps and expansion tanks by detecting pressure fluctuations earlier
  • Increase energy efficiency, because constant system pressures ensure optimal heat distribution
  • Reduce the workload for specialist companies by reducing the number of service calls, manual refills, and recourse

Especially in existing buildings or for customers with little technical know-how, a smart, fully automatic refill solution is the best way to guarantee permanently trouble-free heating systems.

A real benefit for HVAC companies

As a specialist company, you benefit in several ways:

  • Quick installation & intuitive menu navigation
  • Weniger Störungen, weniger Rückfragen
  • Scheduled maintenance instead of emergency service
  • Transparency towards your customers
  • Added value with real benefits

And best of all: Heaty Complete PROfessional can be retrofitted at any time—even in existing systems. This allows you to replace even simple reheating valves with an intelligent solution – and provide your customers with better service in the long term.

Conclusion: Today, fully automatic means thinking ahead, securing, and documenting

Fully automatic replenishment with the Heaty Complete PROfessional and our proven mixed-bed resin Vadion pH-Control, because only then can the replenishment quality be as it should be, is much more than just a convenience feature. It is:

  • an early warning system for leaks,
  • an energy-saving measure through constant system pressure,
  • a contribution to standard-compliant operation,
  • and a real relief for your everyday work as a specialist company.

Whether in new buildings or as a retrofit in existing buildings, this solution allows you to reliably secure heating systems and take your service to a new level.
