A radiant panel for use in radiant heating and cooling systems that provides numerous benefits over conventional panels currently in use. The radiant panel comprises an offset hydronic radiant tube channel in which is nested a hydronic radiant tube that obviates the need to thread the hydronic tubes through the joists in a ceiling installation or the studs in a wall installation. In an alternative embodiment, specific emissivity coatings on each side of the radiant panel further promote the efficient transfer of heat. The system provides increased sound isolation and is robust enough to withstand the crushing forces associated with a floor installation.
