What lambda wärmepumpen does

Lambda Wärmepumpen GmbH is an Austrian manufacturer of air-source heat pumps founded in 2019 and headquartered in Kirchbichl, Tyrol. The company develops and produces the EUREKA product line for residential and commercial heating and cooling, serving single-family homeowners, multi-family building operators, and commercial property owners primarily across the DACH region (Austria, Germany, and Switzerland).

The core of Lambda's offering is built around its proprietary 3K-Prozess technology, a patented optimization of heat-pump flow mechanics that the company claims improves heat-transfer efficiency by four to six times. This technology underpins the EUREKA-Luft series, which has achieved a SCOP value of 6.10 in independent testing at the Swiss OST test center — a level the company states outperforms 97% of ground-source heat pumps while using R290 propane refrigerant (GWP of 3 versus 1,920 for R410a). The product range includes residential units (EU10L through EU20L) for single-family and multi-family homes with capacities up to 20 kW, and commercial units (EU35L) with 6-37 kW capacity, all capable of operating temperatures up to 70°C for compatibility with existing buildings. Supporting products include the LAMBDA Regler controller, Energiespeicher (energy-storage) modules, and the Hydrauliklösung ECO compact hydraulic assembly. The Eureka Magna commercial-scale line is scheduled for delivery from Q2 2026.

Lambda operates a partner-driven go-to-market model, distributing exclusively through specialist trade partners (Fachhandelspartner) that customers locate via an online partner finder. Revenue is generated primarily through one-time product sales, with no publicly disclosed pricing (quotes are required through partners). The company has expanded its corporate family through two acquisitions: Energiereform GmbH & Co. KG in Germany (March 2025) and Huggler Gebäudetechnik in Switzerland (April 2026), establishing local presence in each of its three active markets. As a privately held firm with 11-50 employees, Lambda has been recognized as a 'Millionen-Unternehmen' through consecutive Tiroler Austrian Leading Companies Awards, the inaugural Tiroler Klimaschutzpreis (2025), and the Tirol Change Award (2024).
