Legend Hydronics’ VersaTherm Floor System is a low-profile, high-output, snap-fit radiant panel system ideally suited for new construction and renovation projects. The panels snap together in minutes, saving significant labor costs. The 3/4”-thick panels are pre-insulated and naturally water resistant — great for retrofits and basements. VersaTherm’s use of 1/2” tubing allows for greater circuit lengths. Panels are easily cut for tight installations. Tube spacing is 8” on center. The tubing is 100% protected by metal and the entire surface transfers heat.
