Any cooler surface in contact with the slab will try to steal its heat. Remember that your slab will be about 75 degrees F. Mainly, heated slabs radiate outward rather than downward, so insulation on the edges of the slab is most important. The insulation phase is crucial for a radiant floor. The compacted aggregate base is first, followed by a 6 mil polyethylene vapor barrier, then insulation, then rebar or wire mesh, or both. In fact, the basics of a standard pour remain the same. How much easier it would have been to install the tubing in the original slab!īut, if you’re fortunate enough to be planning an original pour, the procedure is simple. I say this because often we work with people faced with the task of pouring a new slab, with tubing, over an already existing slab … and they poured their existing slab only a few years before. ![]() But even then you should think long and hard about the possibilities of converting these areas into heated space at some future date. A woodshed or an outside storage shed with a concrete floor might be a waste of tubing. Of course, there are always exceptions to the rule. For most applications, the tubing and manifold are relatively inexpensive and the mechanical components can be installed even years later. After all, you may change your mind later and regret your lost opportunity. Virtually any concrete pour should contain radiant tubing …even if you have no immediate plans to heat the space. The fact remains that installing radiant tubing within a concrete slab is probably the easiest, most cost effective, and highest performance application of the science. Starting the Pour: Note that it’s okay to walk on the tubing. The 7/8″ PEX is not delicate and easily withstands the stress of the heavy hose. The final result will be a beautiful, radiantly heated sunroom.Ī pumping unit was used to fill the form with concrete.
