An improved hydronic radiant heating system (10) comprising a nonstructural board (12) having a recess (14) formed in one surface (16) of board (12), and a pipe (18) located within recess (14). If desired, a film of metal (20) can be applied to surface (16) of board (12) with a thickness proportional to the thermal properties of board (12) to provide desired overall thermal characteristics for heating system (10). |
