Question: Who is  Baxi part of now that they agreed to merge with with De Dietrich Remeha ?
Context: De Dietrich Ferroviaire (DDF) is a French manufacturer of railway rolling stock based in Reichshoffen, France.  It was formed as a division of the De Dietrich group, which has a history going back to 1684. Lorraine-Dietrich was a French automobile and aircraft engine manufacturer from 1896 until 1935, created when railway locomotive manufacturer Société Lorraine des Anciens Etablissments de Dietrich and Cie (known as "De Dietrich et Cie", founded in 1884 by Jean de Dietrich) branched into the manufacture of automobiles.  The Franco-Prussian War divided the company's manufacturing capacity, one plant in Niederbronn-les-Bains, Alsace, the other in Lunéville, Lorraine. De Dietrich Remeha is one of Europe's biggest manufacturers and distributors of domestic and commercial water and space heating systems.  Headquartered in Apeldoorn in the Netherlands, it was founded in July 2004 after a merger between the Dutch firm Remeha, and the French firm De Dietrich Thermique.  In July 2009, the heavily laden with debt British Baxi group agreed to merge with De Dietrich Remeha, creating the BDR Thermea Group. CFL's 2000 Class is a series of electric multiple units used on the Luxembourg railway network.  They were built in 1990-1992 by a consortium of De Dietrich, ANF and Alsthom and are similar to SNCF's Z 11500 class. The Type 2 was a prototype automobile designed by Ettore Bugatti in 1901.  It won an award at the Milan Trade Fair that year and gained the notice of the Baron de Dietrich.  De Dietrich managed an automobile factory in Niederbronn in Alsace, France, and contracted Bugatti to develop new models for him under the De Dietrich-Bugatti marque. Baxi is a part of BDR Thermea, one of Europe's largest manufacturers and distributors of domestic and commercial water and space heating systems. Lorraine-Dietrich was a French automobile and aircraft engine manufacturer from 1896 until 1935, created when railway locomotive manufacturer Société Lorraine des Anciens Etablissements de Dietrich et Cie de Lunéville (known as "De Dietrich et Cie", founded in 1884 by Jean de Dietrich) branched into the manufacture of automobiles.  The Franco-Prussian War divided the company's manufacturing capacity, one plant in Niederbronn-les-Bains, Alsace, the other in Lunéville, Lorraine. Baron Philippe Friedrich Dietrich, (also called fr: Philippe-Frédéric de Dietrich) born 14 November 1748 in Strasbourg, and guillotined on 29 December 1793 in Paris, was a scholar and Alsatian politician.  He was most well known as the first mayor of Strasbourg who encouraged Rouget de l'Isle to write various patriotic songs, including the song which became known as "La Marseillaise", first performed in his living room; he is also known as a scientist, author of a mine survey and the development blast furnaces in France, distinguished geologist and chemist, and member of the Academy of Sciences.  As mayor of Strasbourg, he accelerated revolutionary reforms throughout the region. VIRM trains, full name Verlengd InterRegio Materieel ("Lengthened interregional rolling stock"), are a series of electric multiple unit (EMU) double-deck trains operated by Nederlandse Spoorwegen or NS ("Dutch Railways"), the principal railway operator in the Netherlands.  NS has 178 of these double-deckers – 98 four-carriage sets, and 80 six-carriage sets.  The trains were built between 1994 and 2009 – for the most part by Talbot, part of Bombardier Inc., with some railcars built by De Dietrich. The BDR Thermea Group is a European manufacturer of domestic and industrial heating appliances.  The firm was created by the merger of Baxi and De Dietrich Remeha in 2009.
