EUREKA Air Series
LAMBDA Heat Pumps is a multi-award-winning technology leader in energy-efficient air-source heat pumps. Our product range stands for innovation, quality, and sustainability—it heats and cools efficiently, reduces energy costs, and protects the environment. The Eureka-Luft series saves up to 30% in operating costs compared to the highest energy efficiency standard, A+++, making it more efficient than 97% of all ground-source heat pumps.
Energy Efficiency - The 3K Process® as the Industry Standard
The successful implementation of the 3K Process® for heat pumps has marked a quantum leap in the industry. As a result, LAMBDA heat pumps are among the most energy-efficient in their class. Thanks to optimized and patented fluid dynamics, we have succeeded in significantly improving heat transfer → by a factor of four to six.
High temperatures for new construction and existing buildings
Not just for new construction our heat pumps are designed for operating temperatures of up to 70°C. This allows us to ensure effective thermal protection against Legionella, a higher efficiency for your PV system, and high flow temperatures in existing buildings.
Natural refrigerant propane (R290)
For us, sustainability isn’t just about developing highly efficient heat pumps; it’s also reflected in our consistent use of the natural refrigerant propane (R290). With a Global Warming Potential (GWP) of just 3, we’re not only saving you money but also helping to protect the climate. By comparison, the widely used refrigerant R410a has a GWP of 1920.

Despite significantly higher efficiency, LAMBDA heat pumps are priced at roughly the same level as similar competing products. This outstanding value for money stems from the high heat transfer achieved through the 3K process, which has allowed us to keep material costs for air heat exchangers relatively low. Furthermore, our motto is: More machine, less housing. We prefer to invest in high-quality, well-dimensioned refrigeration circuit components rather than in expensive designs.
When comparing products, the model designation is often misleading. The model designation of our heat pumps is based on the maximum output at an outdoor temperature of -10°C. For most other heat pump manufacturers, the model designation corresponds to the maximum output at an outdoor temperature of 2°C or 7°C.
The ideal installation location for an air-source heat pump depends on several factors.
The following points should be considered when selecting an installation location for an air-source heat pump:
- Compliance with safety zones (e.g., no basement shafts or ignition sources within a 1-meter radius)
- Free air circulation (avoidance of niches, obstacles, depressions, and obstructions in front of the heat pump, etc.) to ensure efficiency and reduce noise
- Connection lines to the boiler room should be as short as possible
- Accessibility for servicing
- Noise pollution (compliance with required distances to neighboring properties based on noise calculations, distance from bedroom windows or quiet areas)
Yes! LAMBDA heat pumps offer a wide range of hydraulic systems and accessories.
These include solutions that are perfectly tailored to our heat pumps, such as buffer tanks, hygiene tanks, domestic hot water tanks, combination tanks, and fresh water systems.
New Remote Maintenance Portal “Connected Heat” – All the Details
Our new remote maintenance portal has been online for several months now. With “Connected Heat,” our customers and partners now have round-the-clock access to their LAMBDA heat pump—along with a host of additional features. Here’s how it works.
Given the growing demands for energy efficiency and comfort, remote maintenance of heat pumps has become indispensable in modern building technology. Technicians who must be physically on-site for even the smallest troubleshooting not only drive up (maintenance) costs but also result in delays and potential operational interruptions.
Monitor, control, and maintain remotely
LAMBDA’s “Connected Heat” remotemaintenance portal offers an efficient solution to precisely these challenges. With the help of this newly developed, multifunctional platform, end customers, service technicians, and installers can remotely access the devices and, if necessary, make optimizations or analyze and, in many cases, resolve malfunctions.
Features at a glance:
- Remote access to heat pumps: Partners can independently enable and manage remote access to their customers' heat pumps.
- Customer and employee management: The system enables easy management of customer and employee data.
- Integration with the company website: Company master data is linked to the company website (“Find a Partner”), which simplifies updating and management.
- Centralized management of fault reports: Fault notifications via email can be managed centrally.
- Quick access to heat pump information: Important information such as customer details, status, type, serial number, and software versions is easily accessible.
- Storage and retrieval of documents and notes: Users can store important documents and notes (hydraulic diagrams, maintenance reports, logs, etc.) and retrieve them as needed.
Through continuous monitoring, potential problems can be detected early and addressed proactively before they lead to major outages. Thus, “Connected Heat” offers an advanced, user-friendly solution that optimizes operations and increases overall efficiency. The portal’s features are also constantly being expanded.
Another benefit for you: We have already transferred all systems—including existing ones—to the new platform. This means you no longer need to work with the old platform. New systems are also registered directly on the platform.
