What Vallox GmbH does

Vallox GmbH is a privately-held German manufacturer of ventilation systems with heat recovery (Wärmerückgewinnung), headquartered in Dießen am Ammersee, Bavaria, and founded in 1992. The company designs and sells central and decentralized ventilation units across multiple product lines: Basic Line (entry-level residential, both single-room and whole-building), Professional Line (smart MV units with demand-controlled autonomous regulation and building management integration), and Commercial Line (high-performance units up to 6,000 m³/h for commercial buildings and multi-family residences, including airDIRECT devices). Heat recovery efficiency is stated at up to 93%, and the product range spans airflow capacities from 20 m³/h to 6,000 m³/h. Supporting products include the ValloFlex air distribution system, MyVallox smart home control, Feuchte-Differenz-Steuerung (humidity differential control for basement ventilation), and airCAREs air purifiers.

Vallox's business model is built around three revenue streams: hardware sales of ventilation units across the Basic, Professional, and Commercial lines; recurring filter and accessory sales through its direct e-commerce shop (shop.vallox.de), with filter prices ranging from approximately €29.80 to €436; and professional services including project planning for commercial installations and a structured installer/planner seminar program (BASIC Kompakt, ADVANCED Kompakt, SPEZIAL, PLANER). Go-to-market is dual: direct-to-consumer e-commerce for residential accessories and filters, and project-based enterprise sales for commercial and larger residential installations requiring custom planning proposals. Distribution is restricted to Germany, with DPD standard shipping at €7.00 per order.

The company is solely managed by Geschäftsführer Malte Knief, with Nicole von Thülen heading marketing. Vallox claims the leading position ("Nr. 1") in German residential ventilation with heat recovery and serves four primary segments: single-family homes, multi-family homes, commercial buildings, and schools/educational facilities. No external investment, parent company, or M&A activity was disclosed; the company is independently owned and operated. Recent strategic emphasis is on product line extensions (ValloPlus 520, Basic Line B70/B70 E, FDS) and integration into building management systems, with no announced geographic expansion beyond Germany.
