A low mass hydronic radiant floor heating system for heating a room by circulating a liquid includes a metal deck having a plurality of regularly spaced troughs to provide structural strength. The deck is adapted to be secured directly to a plurality of floor joists. Tubing is placed in the troughs to distribute heat by circulating warm liquid through the tubing. The troughs of the metal deck support structural floor loads while providing a housing for the tubing. Flat portions of the deck between the troughs distribute heat laterally.
