Jeremias

What Jeremias does

Jeremias Abgastechnik GmbH is a German, family-owned manufacturer of modular chimney and exhaust systems headquartered in Wassertrüddingen, Germany, founded in 1984 by Stefan Engelhardt on the foundation of his father Walter Engelhardt's 1970 chimney renovation business. The company operates 10+ production sites globally and employs 1,400+ people, with 460+ employees in Germany and a presence in approximately 60 countries. Its product portfolio centers on element chimney systems — single-wall (EW-FU, EW-ALBI, EW-SILVER, EW-LINE FLEX variants, EW-KL, EW-PPS, EW-PP-FLEX), concentric/LAS (TWIN-GAS, TWIN-PL, TWIN-P), and double-wall stainless-steel (DW-FU, DW-AL, DW-SILVER, DW-ECO 2.0, DW-BLACK, DW-KL, DW-VISION, DW-POWER) — built primarily from V4A stainless steel grades (1.4404/316L, 1.4571/316Ti, 1.4539/904L), polypropylene (PP), and aluminum. Technical differentiators include a proprietary metallic conical connection (EW-KL) achieving pressure tightness up to 5,000 Pa and 600°C operation for CHP and emergency generators, and 904L-based EW-SILVER enabling condensing operation even after soot fire for biomass applications. The portfolio extends to industrial chimney systems (FSA, FSB, FS-RM series, Gittermastschornstein, Lüftungsturm, Rauchgasleitung, industrial silencers), EKKOAIR ventilation units (GENIUS, ROOMMASTER, LOGIC, HOUSE), lightweight chimneys (FURADO, LUX), stove pipes (FERRO-LUX, ISO-LINE, PELLET-LINE), and accessories. CE certifications against DIN EN 1856-1/2 and DIN EN 14471 plus building authority approvals (e.g., Z-7.1-3374 for EW-SILVER) underpin the regulatory moat.

The company serves three customer segments: (1) private residential end-customers reached indirectly via certified Schornstein-Partner chimney installers; (2) commercial and light-industrial customers including industrial bakeries, pizza ovens, coffee roasters, CHP/emergency generators, and decorative gas fireplaces; and (3) heavy-industrial customers (power plants, manufacturing facilities) requiring custom-engineered large-scale steel chimneys. Co-developed system certifications with 10+ decorative gas fireplace OEMs (Faber/Glen Dimplex, Bellfires, Element4, Ortal, STUV, Attika, Camina Schmid, Max Blank, Hoxter, Metalfire) embed Jeremias systems at the appliance specification layer. Disclosed enterprise references include Dutch industrial bakery Molenaar Banket BV, executed with installation partner OBS Techniek and smoke-extraction supplier Exodraft.

The business model is project-based B2B distribution. Revenue streams comprise one-time product sales (modular chimney and exhaust systems, accessories) and professional services (consulting, planning, assembly, transport, sound measurement, condition monitoring). GTM combines: direct enterprise field sales with two dedicated sales directors (Alexander Wening for Elementschornsteine, Peter Veit for Industry Systems); a certified installer channel (Schornstein-Partner) for residential; a self-service B2B portal (My Jeremias at my.jeremias.world) with live ERP pricing, intelligent filters, and EDI integration; and wholly-owned international subsidiaries across Europe and the US. Pricing is quote-based with a published 2026 price list (launch March 2026); 25-year warranties on stainless steel systems and 6-year on PP systems support a quality premium. The company is family-owned (inhabergeführtes Familienunternehmen) with no external PE/VC ownership disclosed, growing organically and through strategic acquisitions. Recent inorganic moves — Avantea Steel Solutions A/S (Denmark, 2023, minority), Xvent s.r.o. (Czech Republic, 2024, majority), and Baetulenn Technik S.L. (Spain, 2025, full) — are extending the portfolio into steel supply, ventilation/climate, and commercial aerothermal/heat-pump solutions, signaling a deliberate platform expansion beyond the residential and industrial chimney installation replacement cycle.

Scale indicators6 records

Recent moves13 records

Expansion highlights6 records

Regional players

• Ofenhaus (Ofenhaus GmbH & Co. KG): Ofenhaus is an Austrian/German specialist in stove pipes (Ofenrohr), fireplace inserts, and related chimney accessories. It overlaps with Jeremias' FERRO-LUX, ISO-LINE, and PELLET-LINE stove pipe product families.

Emerging players

• Bremerhaven Stahlbau (industrial chimneys): Bremerhaven Stahlbau fabricates industrial steel chimneys, lattice towers, and flue gas ducts comparable to Jeremias' FSA, Gittermastschornstein, and Rauchgasleitung product lines for power, refinery, and chemical industry customers.

Direct peers

• Poujoulat: Poujoulat is a French family-owned manufacturer of stainless steel chimney flues, industrial chimneys, and exhaust systems, with subsidiaries across Europe. It is the closest direct competitor to Jeremias in product breadth, material specification, and customer base (heating installers, industrial projects, biomass, condensing boilers).
• Dinak: Dinak is a Spanish manufacturer of modular stainless steel chimney and flue gas systems for residential, commercial, and industrial applications. It competes directly with Jeremias in the Iberian market and across concentric (LAS), single-wall, and double-wall product lines with similar CE-certified specifications.
• Raab Kamin (Raab GmbH): Raab is a German family-owned manufacturer of double-wall stainless steel chimneys, lightweight chimneys, and industrial chimney systems. It is a direct regional competitor to Jeremias in Germany across element chimneys and industrial chimneys.
• Centrotherm Systemtechnik: Centrotherm is a German manufacturer of plastic (PP) and stainless steel exhaust systems for condensing boilers and heat pumps, with strong overlap to Jeremias' EW-PPS and EW-PP-FLEX polypropylene product lines. It is a direct competitor in the condensing boiler and gas heat pump exhaust segment.
• Schiedel (Kingspan Group): Schiedel is one of Europe's largest manufacturers of chimney and exhaust systems, with a product range spanning residential element chimneys, industrial chimneys, and ventilation. Now owned by Kingspan Group, it competes head-to-head with Jeremias across single-wall, double-wall, and concentric stainless steel systems in German-speaking and broader European markets.

Broad incumbents

• Vaillant Group: Vaillant is one of Europe's largest heating technology groups (gas boilers, heat pumps, ventilation) and is a customer-adjacent peer. While Vaillant does not manufacture chimney systems, it sits in the same installer/specifier ecosystem and is a potential partner or competitor for Jeremias' push into heat pump compatible exhaust solutions.
• Selkirk Corporation: Selkirk is a major North American manufacturer of chimney, venting, and air distribution products for residential and commercial HVAC. It is part of the larger DuraVent/Corten group and competes with Jeremias' US business on residential gas venting and chimney relining.
• Stelrad (Ideal Heating): Stelrad/Ideal Heating is a broad incumbent radiator and heating solutions manufacturer serving residential and commercial European markets. While not a chimney specialist, it touches Jeremias' customer base through installer channels and competes indirectly in the heating system value chain.
