A radiant panel includes a first and second skins and a fluid conduit between the first and second skins. The first and second skins each include an inner face and an outer face. The fluid conduit is formed in multiple rows, and is positioned within thermally conducting brackets bonded to an inner face of at least one of the skins. The thermally conducting brackets provide a thermally conducting path between the fluid conduit and the first and second skins of the radiant panel.
