NordBau 2025: Future-proof energy systems for modernization and new construction

• Sound-optimized heat pumps for modernization or new construction
• Modular electricity storage for greater independence from the power grid and adaptation to individual requirements
• Photovoltaic modules for efficient electricity generation
• Professional support with subsidy applications

Neumünster/Allendorf (Eder), September 10, 2025 – Anyone looking to modernize their heating system or searching for a system for their new build should visit Viessmann Climate Solutions at NordBau in Neumünster. In Hall 7 at Stand 7131, the company will be presenting the latest future-proof solutions for homeowners from September 10 to 14, 2025. Whether heat pumps, hot water storage tanks, photovoltaics, electricity storage, charging stations, or ventilation systems – all components are optimally networked and come from a single source. Of course, any other new product can be integrated into the Viessmann Platform One Base. Viessmann Climate Solutions is part of Carrier Global Corporation (NYSE: CARR), the world's leading provider of intelligent climate and energy solutions.

Perfectly coordinated system components

Only the perfect interaction of individual components makes it possible to exploit the full potential of innovative, cutting-edge technology. Viessmann heating components not only set high standards in terms of quality, reliability, and efficiency, but are also part of a harmonious overall system in which all elements are optimally coordinated.

Heat pumps for modernization and new construction

Among other things, the exhibition features the particularly quiet and efficient Vitocal 252-A air/water heat pumps for replacing gas and oil heating systems, as well as the Vitocal 250-AH hybrid heat pump for integrating existing gas or oil boilers, thus meeting the 65 percent renewable energy requirement stipulated by the Building Energy Act (GEG).

The heat pumps use the natural, climate-friendly refrigerant propane and can easily reach flow temperatures of up to 70 °C even at low outside temperatures. This means that existing radiators can usually continue to be used when modernizing.

Greater independence from the power grid

Homeowners can cover a large part of their electricity requirements for heat pumps and other electrical appliances with self-generated electricity, making them less dependent on the public grid. To this end, Viessmann presents system solutions for electricity, heat, and electromobility, such as the latest photovoltaic modules, the modularly adaptable Vitocharge VX3 electricity storage system, and the Viessmann Charging Station for charging electric vehicles. The uniform One Base electronics platform facilitates the commissioning of all components and, thanks to its integrated energy management system, enables the visualization and optimization of heat and electricity flows, which can be individually adjusted via the ViCare app.

Apply for subsidies easily

Viessmann Climate Solutions is cooperating with its partner Energiegestalter (formerly FörderProfi) to support heating system owners in applying for subsidies. An online checklist can be used on the website www.viessmann.de/de/services/energiegestalter to check eligibility for subsidies and identify modernization options with potential savings.
