ELWA

What ELWA does

ELWA (Elektro-Wärme GmbH & Co. KG) is a third-generation family-owned German manufacturer of industrial electric heating equipment, founded in 1931 by Dipl.-Ing. Anton Hilpoltsteiner and headquartered in Maisach near Munich, where it operates a 6,400 m² production facility. The company employs 51–100 people producing electric flow heaters (Durchlauferhitzer), tank heaters, pre-heating modules, and modular Power-to-Heat (P2H) systems under the ERH 4600/4700/800 series and KVE/KVES/KVD/KVT modules. Its product portfolio targets five verticals: renewable energy/utilities (P2H for converting excess electrical energy into heat and grid stabilization), shipbuilding (engine preheating and HVAC for commercial and naval vessels), general industry (process heat for steel mills, food processing, and manufacturing), power plants, and motorsport test rigs.

ELWA's underlying technology centers on electromechanical engineering rather than digital systems: heating elements are individually exchangeable for serviceability, P2H units react within one second to grid signals, and clusters scale from individual units to GW-range installations via modular architecture. The company holds an extensive certification stack—ISO 9001/14001, TÜV EN ISO 3834-2 and AD 2000 HP0/HP100R for pressure equipment, plus marine approvals from DNV, ABS, BV, CCS, and RINA—that qualifies its products for European pressure equipment directives and international shipbuilding. Engineering services including consulting, custom design, production, maintenance, and spare parts are bundled with hardware sales.

ELWA's business model is project-based with quote-based, non-publicly-disclosed pricing on customized hardware. The company sells large-scale P2H systems and complex industrial installations through direct enterprise sales, while distributing standardized products via an authorized dealer network in Norway, Finland, Greece, China, Singapore, and Thailand. Documented flagship customers include the Oberhausen Power Plant (two 11 MW P2H units for grid stabilization), Windpark Fuchstal (4.7 MW P2H paired with battery storage and 5,000 m³ thermal storage), Public Swimming Bath Innsbruck (1 MW P2H for district heating), and the San Francisco Power-to-Liquid facility (P2H for methanol synthesis preheating). Service contracts cover the DACH region, and revenue streams combine hardware sales with recurring engineering and spare parts services.

Product overview

ELWA (Elektro-Wärme GmbH & Co. KG) is a third-generation family-owned German manufacturer of industrial electric heating equipment, operating since 1931 from Maisach near Munich on a 6,400 m² production facility. The core product portfolio centers on electric flow heaters (Durchlauferhitzer) and related thermal systems. The primary product lines include the ERH flow heater series (ERH 4700 Compact, ERH 4600 WR/RF, ERH 800 WR/RF) designed for heating liquids and oils in shipbuilding, industry, power plants, and motorsport applications; pre-heating modules (KVEc, KVE/KVES, KVD/KVT series) for warming fluids in industrial processes; and the flagship Power-to-Heat (P2H) system, which converts excess electrical energy from renewable sources into thermal energy for grid stabilization and sector coupling. The P2H line ranges from 1 MW to 22 MW per installation, with scalable units reaching into the GW range through clustering. Beyond hardware, ELWA provides engineering, consulting, production, and maintenance services as a unified offering.
