Weishaupt Italia Spa

What Weishaupt Italia Spa does

Weishaupt Italia S.p.A. is the Italian operating subsidiary of the privately-held German Weishaupt Group (Max Weishaupt GmbH), headquartered in Gerenzano, Province of Varese. The company designs, sells, and services high-efficiency industrial combustion systems — gas, oil, dual-fuel, and multi-fuel burners with power ratings up to 32 MW — together with industrial steam generators (fire-tube and water-tube) and water-treatment systems (softeners, reverse osmosis) for steam-generator feedwater. Its proprietary combustion technology, most notably the multiflam® 3LN/4LN multi-flame burner architecture, achieves NOx emissions as low as 30 mg/m³ with external flue gas recirculation, positioning the product line against EU 2015/2193 and IED 2010/75/EU emission regimes.

The company has expanded beyond combustion into decarbonization-aligned heating: the Aeroblock® WAB air-to-water heat pump series (R290 natural refrigerant, A+++, SCOP >4.7, supply temperatures to 70°C), Geoblock® geothermal heat pumps (SCOP up to 5.2), Splitblock® split-configured heat pumps, and hybrid heat-pump + condensing-boiler systems with a dual-compensator hydraulic configuration. Green Fuels Ready certification of the W30-40, WM 10-50, and WK burner series extends the portfolio to renewable liquid fuels (GF-M, GF-P, GF-B30, GF-B100/FAME). Digital combustion management and Bus-based Building Automation integration are supported via the Digital Burner Manager.

Go-to-market is a direct enterprise field-sales model executed through an Italy-wide branch ('filiali') network, with technical offices supporting specification, commissioning, and after-sales maintenance, augmented by an online product configurator and a content-led blog (blog-energia) with newsletter capture and downloadable PDF guides. Revenue streams comprise hardware sales of industrial burners, heat pumps, and hybrid systems, plus recurring technical-service, maintenance, water-treatment, and revamping/retrofit revenues. Customer segments are diversified across industrial/manufacturing (foundries, metalworking, food, ceramics, textiles, district heating), residential/condominial (single-family to multi-family buildings, including retrofit), and commercial/tertiary (offices, schools, hotels, restaurants). Pricing is quote-based and configuration-driven; no public price list is disclosed.
