Wilhelm Schetter

What Wilhelm Schetter does

Wilhelm Schetter GmbH Haustechnik is a family-owned building-services-engineering company headquartered in Kernen im Remstal, Baden-Württemberg, Germany, founded in 1923 and operating across two sites with approximately 300 employees. The firm plans, builds, and maintains technical building infrastructure for two principal customer groups: residential homeowners (single-family heating, bathroom, air-conditioning, and photovoltaic projects acquired via online offer calculators) and industrial and commercial enterprises (manufacturing facilities, automotive dealerships, energy companies, and wine cooperatives requiring HVAC, industrial refrigeration, energy centers, and building-automation systems).

The technology stack spans the full energy-systems portfolio — steam and hot water plants, gas/oil, biomass, combined heat and power (BHKW), geothermal and heat pumps, fuel cells, solar thermal, PV, and industrial refrigeration — combined with building services (heating, ventilation, AC, sanitary, measurement-control-regulation / MSR, clean-room) and an internally developed MSR-Frontend for standardized, CI-compliant, remote-capable visualization and operation of facility systems. Building Information Modeling (BIM) is used for digital planning.

Revenue is generated through three streams: one-time engineering and installation contracts for energy systems and building technology; recurring technical facility management, maintenance, and 24-hour emergency services; and Contracting arrangements under which SCHETTER owns and operates client energy assets on a recurring basis. Enterprise projects are won through project-account-managed direct field sales, while residential leads flow from online calculators and self-service estimate tools. The firm holds Fachbetrieb Wärmepumpe certification (since 2024), is 100% CO2-neutral in its own operations (since 2021), and has documented 27,500+ completed projects since founding.
