EM-plan

What EM-plan does

EM-PLAN GmbH is an independent German engineering and planning office specializing in technical building equipment (TGA - Technische Gebäudeausrüstung), particularly surface heating and cooling systems within the SHK-Branche (heating, plumbing, ventilation, and sanitation industry). Founded in January 2014 as a subsidiary of EMPUR Produktions GmbH and headquartered in Marburg with a branch office in Chemnitz, the company serves wholesale partners and trade craftsmen (SHK-Handwerk) throughout Germany with a team of experienced TGA engineers. Its service portfolio covers complete HLS (heating, ventilation, sanitation) planning including heat load and cooling load calculations per DIN EN 12831-1, pipe network calculations with pressure loss analysis, ventilation concepts, drinking water and wastewater planning, energy-optimized building concepts, GEG certificates per DIN 18599, and 3D building model-based documentation. In addition to planning services, the company supports and markets the EMPUR product ecosystem including the CUT-THERM® milling system for renovation, PUR-THERM® composite and insulation boards, KLIMAPEX® plastic heating pipes, top-NOPP® nub systems, OPTIMAL 25 dry construction system, electric thin-bed heating mats, and the Alpha Smartware IoT control platform with smartphone app integration.

The business operates primarily on a project-based professional services model, with quote-based pricing for planning packages (Technikpakete and Komplettpakete) such as heat load calculation packages for new underfloor heating installations, heat load packages for existing heating systems, and complete HLS planning packages for new construction and renovation. Go-to-market combines direct enterprise field sales targeting the SHK-Branche with a three-tier distribution model (dreistufiger Vertrieb) via wholesale partners (Großhandelspartner) who serve trade craftsmen, supported by regional field sales representatives covering territories such as Hessen, Sachsen-Anhalt, and Thüringen. Effective January 1, 2025, the company became part of 3U Holding AG through the acquisition of the broader EMPUR group, with EM-plan continuing to operate as an independent subsidiary. The company has accumulated over 3,800 HLS planning projects, 175 million watts of planned heating capacity, and 123 million meters of underfloor heating pipe installed across its history.

Direct peers

• Uponor: Nordic specialist in underfloor heating, cooling, and plumbing systems with a strong position in Europe. Uponor offers both products and digital planning/control tools — directly comparable to EM-plan's combined planning-services-plus-EMPUR-products offering, though at much larger European scale.
• Kermi (Arbonia Group): German manufacturer of radiators and underfloor heating systems within Arbonia Group. Directly comparable product overlap (surface heating) and channel overlap (SHK wholesale) with EM-plan/EMPUR.
• TECE: German family-owned provider of plumbing, heating, and underfloor heating systems with proprietary planning software and SHK-channel distribution. Directly comparable mid-sized competitor for both products and planning tooling.
• Roth Industries: Family-owned German manufacturer of plastic pipe systems, surface heating/cooling, and heating distribution — including renovation-friendly low-build-up systems directly comparable to OPTIMAL 25 and CUT-THERM. Operates in the same SHK installer channel in Germany.

Broad incumbents

• REHAU: Global polymer-based systems provider with a strong heating, plumbing, and underfloor heating business plus proprietary digital planning software (RAUCAD). REHAU is a direct competitor in the German surface-heating space, selling through the same SHK wholesale channel as EM-plan/EMPUR, but operates at much larger scale and with bundled product+planning offerings.
• Buderus (Bosch Thermotechnology): Major German HVAC brand under Bosch Thermotechnology offering boilers, heat pumps, and integrated heating distribution including underfloor systems. Buderus competes for the same SHK trade-craftsmen and wholesale-partner relationships that EM-plan serves, with substantial planning-support resources.
• Viessmann: One of Germany's largest heating technology manufacturers (boilers, heat pumps, hybrid systems, underfloor heating) with its own digital planning tools (ViPlan, ViCare). Viessmann competes directly in surface heating and controls, and — like EM-plan — leverages SHK installer relationships; its broad portfolio dwarfs EM-plan's niche.
• Danfoss: Global leader in HVAC controls, sensors, and hydronic balancing — including smart thermostats and IoT platforms. Danfoss is a particularly relevant peer for EM-plan's Alpha Smartware line, and competes in the same SHK/wholesale channel with controls offerings.
• Watts Industries (Watts Water Technologies): Global manufacturer of HVAC, plumbing, and water-quality products including underfloor heating components and hydronic controls. A relevant broader peer for the EMPUR product family and EM-plan's planning-support capabilities.
• Stiebel Eltron: German heating, hot water, and heat pump specialist with a growing footprint in surface heating systems. Competes for the same installer/wholesale channel and for renovation projects where EM-plan's CUT-THERM-style solutions are positioned.
