Siegfried Vogel from Wachtberg and Norbert and Birgit Pieplow from Niederkassel were on the same trip on Saturday. It was the 12th Bonn construction and real estate fair, organized by General-Anzeiger at the Telekom Dome in Hardtberg. However, her visit was only aimed at one of the nearly 30 exhibitors: Frank Becker, owner of the BME-Technik company in Pützchen, who was presenting an unusual energy storage device for building heating at his trade fair stand. The highlight of the matter: Becker’s heating system was designed specifically for old houses. In simple terms, it integrates renewable energies such as solar, wind and hydro power and uses this green power to generate heat up to 160 degrees. According to Becker, the primary heat is stored in steel containers embedded in quartz sand. The heart of the heating technology was also on display at the trade fair. Vogel and Pieplow can imagine climate-friendly heating in their own home in the future. After all, they are one of the dominant groups of homeowners who heat their homes with fossil fuels.
