LINK3 offers innovative stratified storage tanks for an efficient and sustainable energy supply. By optimising the use of renewable energy sources – such as heat pumps, district heating, heat recovery or solar energy – our products set new standards in domestic hot water generation and heating technology. Our solutions stand out through a noticeable reduction in energy consumption and space requirements – efficient, space-saving and future-proof.
Our Product Family
ECOLINK -New
The ideal stratified storage tank – especially for heat pumps
Optimally matched to heat pumps with underfloor heating systems without active cooling; the most cost-effective entry into LINK3 technology. With a capacity of 500 litres (equivalent in performance to approx. 750 litres of conventional storage tanks), a diameter of just 650 mm (uninsulated) and a height of 1,830 mm (insulated), it is a true space-saving solution.
DUOLINK -Cool
Heating and cooling in a single stratified storage tank
The DUOLINK heating water manager achieves the highest stratification efficiency among storage-integrated domestic hot water generation systems (without any domestic hot water time window restriction). This has been confirmed by the SPF testing institute in Rapperswil (Switzerland). With a nominal volume of 750 litres, it provides domestic hot water for up to three residential units and can both heat and cool using just one single storage tank – a truly outstanding innovation.
COMFORTLINK -Basic/-Sun/-Plus
Comfortably combining all systems
Maximum efficiency in combining systems with large water volumes – such as heat pumps, underfloor heating and wall heating – with high-temperature heat generators (biomass systems, radiators, warm air heating) and energy-saving concepts (solar energy, heat recovery, condensing technology) is achieved in the private sector with the COMFORTLINK, featuring a volume of 900 litres.The COMFORTLINK-Sun delivers 20–25% higher yields from solar thermal systems, making the solar installation significantly more effective. The new COMFORTLINK-Basic is the entry-level version for single-family homes with maximum storage volume. The COMFORTLINK-Plus is equipped with a second, equivalent domestic hot water heat exchanger. This allows either two separate domestic hot water distribution systems to be established or, for example, a micro-grid connection for transmission capacities depending on primary network temperatures or secondary output of approx. 10–20 kW.
POWERLINK -Basic/-Sun/-Plus
High-performance heating water management for large-scale installations
The POWERLINK – with a volume of 900 litres – is in fact the most powerful and cost-effective solution for large-scale systems. It offers maximum hygiene safety and resilience combined with outstanding energy efficiency and minimal maintenance requirements. A single POWERLINK can supply between 11 and 70 residential units. It can be cascaded as required to serve up to 800 residential units, 500 hotel rooms, 200 hospital or care beds and much more.The POWERLINK is equipped with a circulation heat exchanger to ensure compliant circulation in accordance with B1921 / W551 standards. The POWERLINK-Sun includes a high-performance solar heat exchanger with stratified charging function, increasing solar yields by up to 25%.
SATELLITE-950/-750/-Plus
Satellite storage tanks can be connected in parallel to the main storage unit to increase storage capacity and enable combined applications. Depending on the application, they may need to be locked or enabled via a zone valve in accordance with the respective hydraulic requirements. As a 2026 product innovation, LINK3 presents the SATELLITE-Plus stratified satellite storage tank. Thanks to its intelligent zone allocation, it is the perfect solution for high performance demands in combined large-scale systems and enables entirely new system concepts in heating and cooling applications. It is ideally suited for increasing self-consumption rates, for use in energy communities and for applications involving dynamic electricity tariffs.
We – LINK3 – are an innovative company based at the Wissenspark Salzburg in Puch near Hallein, specialising in the production and distribution of stratified storage tanks. Our storage technology is used for efficient heat and energy supply and is based on a patented system founded on the natural principles of thermodynamics and fluid dynamics.
Since its foundation, LINK3 has pursued the goal of developing sustainable and resource-efficient heating solutions for both residential and commercial applications. Our storage solutions are designed to enable energy savings of up to 30%, while at the same time offering space-saving installation. The highly efficient use of renewable energy sources, together with the combination of all possible generation and consumption systems, makes our technology unique in the fields of domestic hot water generation, heating and cooling.
By combining innovative technologies with modular systems, we create tailored solutions for a wide range of applications – from single-family homes to large residential developments and commercial projects.
We follow a clear sustainability strategy and place great emphasis on efficiency and the reduction of technical components, significantly lowering maintenance and servicing costs while increasing user-friendliness.
At our headquarters in Puch near Hallein, located in the surroundings of Salzburg University of Applied Sciences – a new and inspiring environment that fosters innovation and creativity – we work together towards a sustainable future. Here, we combine contemporary design with technological efficiency to create a working environment that is not only productive but also enjoyable.
This philosophy also shapes the way we support our customers and deliver our services. In an environment that encourages creativity and satisfaction, we are able to develop customer-focused solutions and respond precisely to our clients’ needs.
