Overview
BDR Thermea is an international heating and climate-technology group focused on equipment and solutions for residential, commercial, and industrial buildings. Its business includes domestic and commercial space-heating systems, hot-water equipment, boilers, heat-pump-related technologies, and emerging low-carbon heating systems. The group operates through a portfolio of market-specific trade brands, including Baxi, De Dietrich, Remeha, Brötje, Chappée, and Baymak. Rather than presenting one uniform consumer brand in every market, BDR Thermea uses different established brands according to local customer recognition, installer networks, regulations, and product requirements. The group was created through a series of mergers and acquisitions involving long-established heating companies. Remeha merged with De Dietrich Thermique in 2004, creating the De Dietrich Remeha Group and bringing the Chappée brand into the combined business. In 2009, the De Dietrich Remeha Group merged with the Baxi Group, which included the German Brötje brand. This transaction created BDR Thermea Group and established the corporate structure under which the group has subsequently expanded. BDR Thermea’s growth has included geographic and portfolio expansion. It acquired Baymak in Turkey in 2013, strengthening its presence in a major regional heating market. In 2015, it acquired ECR International in North America, although ECR International was divested in 2021. The group acquired Hitecsa in Spain in 2021, adding further heating, ventilation, and air-conditioning capabilities. Reference material also reports that in 2026 BDR Thermea completed the full acquisition of Italian company G.I. Holding, bringing the CLINT, KTK, NOVAIR, and MONTAIR brands into its portfolio for commercial and industrial HVAC applications. The company has increasingly positioned itself around the transition from conventional fossil-fuel heating toward lower-carbon systems. Its work includes the development and demonstration of hydrogen boilers, participation in European and national hydrogen initiatives, and the development of integrated solutions for decarbonising buildings. In 2019, BDR Thermea installed a high-efficiency hydrogen boiler in a real-world setting in Rozenburg, the Netherlands, in cooperation with gas-network operator Stedin, the municipality of Rotterdam, and housing association Ressort Wonen. The group later supplied boilers for the Hydrogen 2 Lochem project, a Dutch pilot that used the existing gas grid to deliver pure hydrogen to 12 heritage homes. The demonstration ran for three years and concluded at the end of 2025. The group reports a broad international manufacturing and distribution footprint. The supplied reference material describes operations in more than 100 countries, manufacturing at 11 locations in eight countries, and approximately 6,100 employees worldwide. It also reports turnover of around €1.8 billion in 2020; this figure is historical and should not be treated as a current financial result. BDR Thermea’s commercial model emphasizes the distinct needs of installers and end users, which vary by country and by building sector. Its role therefore combines product manufacturing, brand management, technical development, distribution, and support for professional heating and HVAC channels.
History
BDR Thermea emerged from the consolidation of several European heating businesses rather than from the launch of a single new consumer brand. Its corporate ancestry includes Remeha, De Dietrich Thermique, Baxi, and Brötje, among other businesses and brands. This history explains the group’s multi-brand structure: individual names remain important in national markets, while BDR Thermea provides the overarching corporate platform for manufacturing, technology development, distribution, and acquisitions. A major step in the group’s formation occurred in 2004, when Remeha merged with De Dietrich Thermique. The resulting De Dietrich Remeha Group included the Chappée brand and combined complementary heating operations. In 2009, the De Dietrich Remeha Group merged with the Baxi Group. Baxi’s portfolio included the German Brötje brand, and the combination created BDR Thermea Group. The merger brought together established European heating businesses with significant installer and distributor relationships. The group subsequently expanded beyond its original European base. In 2013, it acquired Baymak in Turkey, adding a prominent regional heating business and strengthening its position in Turkey and nearby markets. In 2015, BDR Thermea acquired ECR International in North America. That asset was later divested in 2021, reflecting a change in the group’s portfolio and geographic priorities. Also in 2021, BDR Thermea acquired Hitecsa in Spain, broadening its capabilities in HVAC equipment and commercial applications. Technology development has increasingly been shaped by the decarbonisation of building heat. BDR Thermea has worked on hydrogen boilers as one possible route for reducing the carbon intensity of gas-based heating where suitable infrastructure and policy conditions exist. In 2019, it participated in a real-world hydrogen-boiler demonstration in Rozenburg in the Netherlands. The project involved Stedin, the local municipality, and housing association Ressort Wonen, and was intended to test high-efficiency hydrogen heating under practical conditions. The company also participated in the Hydrogen 2 Lochem project in the Netherlands. Launched as a three-year pilot in late 2022 in the Berkeloord district of Lochem, the project supplied pure hydrogen through the existing gas network to 12 heritage homes fitted with dedicated hydrogen central-heating boilers. The demonstration concluded at the end of 2025. BDR Thermea has also participated in the UK Hy4Heat programme and hydrogen studies and demonstrations in France and Germany. Its 2020 membership of the European Clean Hydrogen Alliance further connected the group with European efforts to develop clean-hydrogen production and use. Reference material reports that BDR Thermea operates in more than 100 countries, manufactures at 11 sites in eight countries, and employs approximately 6,100 people. It reported turnover of about €1.8 billion for 2020. In 2026, the group reportedly completed the full acquisition of Italian G.I. Holding, adding the CLINT, KTK, NOVAIR, and MONTAIR brands. This transaction expanded its commercial and industrial HVAC presence and was presented as part of a strategy to deliver integrated lower-carbon solutions. The group’s current identity is therefore that of a diversified heating and HVAC platform whose brands, products, and technical priorities vary by market.
