About Thermic Energy
Thermic Energy RZ GmbH, based in Borna (Saxony), manufactures thermal storage tanks for solar thermal, heat pumps and modern heating systems. The portfolio includes drinking water storage tanks, high-performance and energy buffer storage tanks, stratified buffer storage tanks, stratified combination storage tanks and custom storage tanks made to customer specification. Manufacturing ranges from punching and laser cutting through bending, heat exchanger assembly and robotic welding to enamelling, in-situ PU foam application and hand-sewn insulation jackets. Key materials are steel and stainless steel, including stainless steel corrugated tube for heat exchangers enabling legionella-free drinking water heating. The in-situ foamed PU insulation meets energy efficiency class A under the Ecodesign Directive. Optimised production processes and modern methods enable high production volumes in Borna.
