The Bosch Buderus Model 21 panel radiator (12" x 36" x 2.5") is a compact hydronic steel unit for new construction and retrofit projects, providing combined radiant and convective heat in a slim, wall‑mounted profile. It features the integrated FlowSetter valve for room‑by‑room flow regulation and compatibility with lower supply temperatures to support consistent, balanced heat distribution.
