x-change dynamic pro air/water heat pump
New build and refurbishment.
Many homeowners shy away from the installation of a heat pump. The x-change dynamic pro heat pump impresses in both refurbishments and new builds. Thanks to its flexible system architecture, it can be easily integrated into existing buildings while offering state-of-the-art technology and maximum energy efficiency for any living situation.
Whether a detached house, apartment block or commercial property: we offer customised solutions that are tailored to individual requirements. Our systems utilise the energy that nature provides us with free of charge. They noticeably reduce operating costs, increase living comfort and make a valuable contribution to climate protection.


Hybrid solution.
Hybrid heating is also a cost-saving solution for refurbishments: It combines the environmentally friendly heat pump with a second heat generator. This allows the existing heating technology to be modernised flexibly and without major conversions. The heat pump efficiently takes over the base load supply, while the second heat generator provides additional power when required.
The hybrid solution scores particularly highly with older buildings thanks to its adaptability and gradual integration. This lowers energy costs, reduces CO₂ emissions and ensures greater independence from rising energy prices.
Sustainable in new builds.
The x-change dynamic pro air/water heat pump is a pioneering heating solution and the centrepiece of modern heating and cooling supply. It utilises free energy from the environment and integrates seamlessly into an overall system: in combination with a sustainable energy supply, intelligent control technology and innovative solutions for heat storage and distribution, it creates a heat pump system with an impressive annual COP. In addition, the integrated PV function utilises surplus energy from the building's own photovoltaic system sensibly and efficiently.

Cascade solutions.
For large projects up to 60 kW. With our cascade solutions, several x-change dynamic pro heat pumps can be combined to form a powerful system. This is ideal for large properties with a heating requirement of 20 to 60 kW (up to 100 kW depending on the project). The intelligent x-center pro control system ensures maximum efficiency and reliability.
Advantages:
- Fail-safe due to redundant operation
- High energy efficiency thanks to intelligent control system
- Very low operating noise and whisper mode
- Modulating operation and automatic runtime optimisation

Heat pump technology for maximum efficiency.
Whisper quiet
The dynamic pro sets standards.
44.5 dB(A) at A7/W55
Efficient
Top class A+++ with COP 4.95 (A2/W35) with the use of sustainable refrigerant R290
Versatile
It can be used as a single or cascade system and delivers a heating capacity of up to 60 kW. Depending on the project, even up to 100 kW - ideal for new builds and refurbishments alike.
Dynamic
Flexible and sustainable heating system that can achieve flow temperatures of up to 70°C regardless of the existing heating system.
PV-Ready
Possibility of efficient utilisation of PV electricity. The excess electricity can be targeted by modulating the compressor and/or activating the heating rods.
Networked
Operation of the x-center pro control unit is operated via touch display or app. Every x-change dynamic pro has the required interface on board.
Connect & Heat
By using the x-buffer pro system storage tank or the hydraulic module pro, the system can be operated temporarily via the heating rods (interim operation).
Remote maintenance
As soon as the x-change dynamic pro is connected to the Internet, remote maintenance is possible. The LAN interface is standard.
Hybrid solution
The integration of a second heat generator can be easily implemented. Of course, the x-center pro takes over the control.
Service
Quick and easy thanks to intelligent assemblies and online access.
