PAUL Wärmerückgewinnung - Wärmetechnik

What PAUL Wärmerückgewinnung - Wärmetechnik does

PAUL Wärmerückgewinnung - Wärmetechnik is a small, privately held German specialist dealer of residential heat recovery ventilation (Wärmerückgewinnung) systems, headquartered in Bitterfeld-Wolfen, Saxony-Anhalt. Founded on April 1, 1997 by Roland Paul, the company operates as an authorized dealer for products manufactured by Paul Lüftung (paul-lueftung.de), distributing that manufacturer's CLIMOS 200, FOCUS 200, NOVUS 300, and NOVUS 450 unit ranges, plus related accessories. The business serves end customers in the German residential market, typically homeowners, renovators, or small installers seeking decentralized or controlled-mechanical ventilation with heat recovery.

The company's core technology is not proprietary — it resells and ships hardware rather than designing or manufacturing it. The product range spans wall- and ceiling-mounted heat recovery units in the roughly EUR 2,700 to EUR 4,600 price band per unit, intended to provide controlled mechanical ventilation with heat recovery for energy-efficient homes. No software, IoT, or smart-control features are documented in the inputs.

The business model is direct hardware sales: customers place orders via email or phone, and the company ships pallets within Germany at a flat EUR 55 freight rate. The firm operates with 6 employees and has no disclosed revenue, no external funding, and no public digital commerce infrastructure in the supplied data. Distribution is domestic-only, with no documented international shipments, B2B channel partnerships, or installer network beyond the direct customer relationship.
