What häusler does

Häusler GmbH is a privately held German skilled-trades company headquartered in Forstern, Bavaria, that installs, maintains, and repairs heating, sanitary, plumbing, ventilation, and energy systems for residential and commercial customers across the Munich metropolitan area and Bavaria. Founded in August 1993 by Wolfgang Häusler as a one-person operation (Ein-Mann-Betrieb), the company has grown to 15 employees supported by a recurring apprenticeship program and operates as a classic German Mittelstand family business with no external investors or parent entity.

The company's service portfolio spans virtually the full SHK (Sanitär, Heizung, Klima) trade spectrum: condensing gas and oil boilers, heat pumps (groundwater, geothermal, ground-collector, air-source), solar thermal, pellet and wood-chip systems, water-carrying fireplaces, residential ventilation with heat recovery, micro-CHP (Remeha E-Vita Stirling), district heating connections, bathroom installations, drinking-water treatment, wastewater lifting stations, hydraulic balancing, and regulatory compliance inspections (Trinkwasserverordnung 2011, TRGI 2008 gas safety). Equipment is sourced through long-standing partnerships with major manufacturers including Buderus, Viessmann, Remeha, Wolf, Fröling, Weishaupt, Weider, Hargassner, Citrinsolar, Speichertechnik, and Jurathner, supported by wholesale relationships with Richter+Frenzel, Gienger, and Sanitär-Heinze.

The business generates revenue through three streams: one-time installation projects (professional services), recurring maintenance contracts covering annual inspections and burner checks (subscription/recurring), and emergency repair services with priority access for maintenance customers. Customer acquisition is direct-to-consumer, driven by local reputation, the company website, and SHK Innung trade-organization membership. Pricing is not publicly disclosed and follows industry-standard German hourly trade rates. Operations are entirely regional, with no disclosed app, API, digital product, or AI/ML capability.
