Core offering

Strawa Heat Technology (strawa Wärmetechnik GmbH) manufactures and distributes heat distribution and fresh water technology products made from stainless steel (VA DIN EN 10088-2). The company produces connection distributors, fresh water stations, heat groups, distribution cabinets, hydraulic separators, control and electrical components, and the modular Friwara WM Systembaukasten system for residential building heating and drinking water applications.

Product overview

Strawa Heat Technology offers a comprehensive portfolio of heat distribution and drinking water technology products 'Made in Germany,' featuring a modular and scalable system architecture. The core product lines include Anschlussverteiler (connection distributors), Anschlussstationen (connection stations), Verteilerschränke (distribution cabinets), Wärmegruppen (heat groups), and Frischwasserstationen (fresh water stations). Central to their apartment-level offering is the Friwara WM Systembaukasten—a modular system kit that enables configuration of complete stations for drinking water heating combined with surface heating, consisting of cabinet modules (FS), connection rail modules (FA), hydraulic modules (FH), distributor modules (FV), and pre-wiring modules (FE). Additional product families include Frischwasser-Wohnungsstationen, Trinkwasserverteiler, Wasserstationen, Energiespeicher, strawacore pump groups, and various specialty stations for industrial, pipe aeration, and ventilation applications. The company also provides digital tools including a product configurator and strawaCAD 3D data service. Products are characterized by patented flow indicators (Regolux), labor-tested stainless steel construction (VA DIN EN 10088-2), and compliance with DIN EN 1264-4 standards.
