Compact Buderus Panel Radiator Model 21 (20" x 24" x 2½") is a space‑saving hydronic steel panel unit for residential and light‑commercial zones, delivering both radiant and convective heat. Its slim 2½" depth suits retrofit or new‑build installations where wall space is limited, and the FlowSetter valve enables room‑by‑room flow balancing for consistent heat distribution. Part 7738003537 was not found on Bosch North America pages; this description is based on Bosch Buderus panel radiator information.
