Revenue model

1. TGA Installation for Large Construction Projects: Revenue is generated through project-based installation contracts for technical building equipment (Heizung, Sanitär, Kälte, Klima). Projects range from multi-year high-rise contracts (e.g., Estrel Tower Berlin, Elbtower Hamburg) to residential quarters and special buildings. Pricing is based on detailed work catalogs (Leistungsverzeichnisse), with early-stage project inquiry and quotation process. Revenue is project-based and one-time per project, though ongoing maintenance is handled by sister company Rhön Service.

Core offering

RHÖN Haustechnik executes technical building equipment (TGA — Technische Gebäudeausrüstung) installation for large-scale construction projects across Germany, covering the four trades of heating (Heizung), plumbing/sanitary (Sanitär), cooling (Kälte), and climate control (Klima). The company serves general contractors, project developers, and building owners with on-site execution including planning coordination, prefabrication, installation by its own dedicated teams, quality assurance, documentation, and commissioning. It specializes in high-rise buildings (up to 245m), hotels, office towers, concert halls, and large-scale research/industrial campuses.

Product overview

Rhön Haustechnik is the large-project specialist of the Rhön Technik Gruppe, offering Technical Building Equipment (TGA) execution services across four trades: heating, plumbing, cooling, and climate. The group operates three distinct brands: Rhön Haustechnik executes HVAC installation for high-rise buildings, concert halls, and campus projects for general contractors and project developers; Rhön Service provides maintenance, repair, and customer service for existing heating, plumbing, and climate installations; and Rhön Tec delivers heat pump installations, bathroom renovations, air conditioning systems, and small commercial projects for private and business customers. Together, the three brands provide a full lifecycle from new construction execution through to ongoing maintenance and servicing.

Direct peers

• ROM Technik: Specialist German HVAC and building services contractor focused on commercial and industrial projects. Comparable niche player in mid-to-large TGA execution with similar customer profile of general contractors and developers.
• Caverion Deutschland: German arm of the Finnish-listed Caverion Group, delivering HVAC, plumbing and building automation for commercial and industrial projects. Closest listed direct peer in terms of MEP installation services and customer overlap.
• Gegenbauer Gruppe: Berlin-based building services and technical facility management group with a strong TGA execution heritage. Direct comparable on German commercial/institutional installation work, especially in the Berlin market where Rhön also operates.
• Kraftanlagen Group: Munich-based specialist in industrial and building-services engineering, with HVAC and process-technology installation across Germany. Direct comparable in technical execution and project orientation, particularly for industrial-campus and energy projects.
• WISAG: One of Germany's largest technical building services and facility management groups, with deep HVAC, sanitary and cooling installation capabilities for commercial and industrial clients. Direct comparable on TGA execution scale and customer base, though operating across a broader service portfolio.

Broad incumbents

• ENGIE Deutschland: German subsidiary of the global ENGIE group, providing facility management, energy services and technical building equipment at national scale. Broad incumbent with overlapping TGA capabilities, but competes as part of a much wider energy and FM portfolio.
• ISS Energy Services (ISS Deutschland): German arm of the global ISS facility services group, with technical building services including HVAC and sanitary installation. Adjacent competitor for technical FM and installation work, operating at much larger scale.
• Dalkia Deutschland: German subsidiary of EDF's Dalkia, focused on energy services, district heating and technical building equipment. Overlaps with Rhön on heating and cooling systems, but at much larger scale and through energy-services contracts.
• VINCI Energies Deutschland: German operations of the VINCI group's energy and information systems business, with significant building technology and HVAC installation capabilities. Broad incumbent covering overlapping TGA scope at national scale.

Others

• STRABAG Property and Facility Services: German facility services arm of the STRABAG construction group, providing technical building services and TGA-related FM. Comparable customer base (real estate developers, corporates) but adjacent rather than a direct specialty-trade competitor.
