In a hydronic heat slab on grade installation – radiant tubing is attached to re-bar or 6×6 wire re-mesh with plastic ties and embedded in cement. In residential installations, a 4 inch slab is typical. Tubing can be installed in the lower half of the slab – spacing and height will vary by design. Slab insulation is recommended, but not always necessary.
The large thermal mass stabilizes temperature fluctuations, but can slow the response time. This is a very cost effective radiant installation method ahydronic heatrecommended whenever hydronic heat is desired and a cement slab is being poured.
