What Bosch Industriekessel does

Bosch Industriekessel GmbH is a German manufacturer of industrial boiler systems for steam, hot water, and heating applications, headquartered in Gunzenhausen, Bavaria, and operating as a wholly-owned subsidiary of Robert Bosch GmbH via the Bosch Home Comfort Group. Originally founded as Loos in 1865 and acquired by Bosch Thermotechnik in 2009 before being renamed in 2011, the company has commissioned more than 120,000 boiler systems in over 140 countries and currently employs 501–1,000 staff across manufacturing sites in Germany (Gunzenhausen, Lollar), Austria (Bischofshofen), the Czech Republic (Krnov), and China (Hefei, for VRF systems).

The product portfolio spans steam boilers (CSB, U-MB, UL-S/UL-SX, ZFR/ZFR-X, ELSB), hot water and heating boilers (Unimat UT-L/M/H/HZ, Uni Condens 8000 F, Condens 7000 series), hybrid boilers combining electric and burner systems, heat recovery systems (HRSB, self-fired waste heat boilers, ERV), VRF air conditioning, and a controls/connectivity layer (Control 8000, BCO/SCO/CWC/CSC, ELC, MEC Remote, MEC Optimize). The company has qualified its portfolio for CO2-neutral fuels — hydrogen, biofuels, biogas, and green electricity — and is actively extending into electric and electrode boiler technology via the 2025 A.E.P. Thermal partnership and ELHB/ELC/ELSB product launches.

Bosch Industriekessel generates revenue primarily through project-based hardware sales of customised boiler systems and a complementary aftermarket stream covering 24/7 service, spare parts, modernisation, and technical training. Go-to-market is enterprise field sales targeting industrial customers in food & beverage, pharmaceuticals, manufacturing, district heating, and large public buildings, supplemented by regional channel partners and an active trade-fair programme (ISH, ACHEMA, BrauBeviale, Anuga FoodTec). Pricing is quote-based on multi-year project contracts, with no publicly disclosed price list.
