Concrete Hydronic Radiant Floor Heating

As warm water circulates through the tubing or as electricity warms the heating elements the concrete flooring turns into an efficient inconspicuous radiator.

Concrete hydronic radiant floor heating.

These are sold in pairs supply and return and include flow indicators flow regulating valves and other basic components. The system works via pex pipe a small pump a water heater and a thermostat. Typically radiant heating systems warm floors to temperatures of 75 to 80 degrees f. Radiant heat manifolds designed for use with 3 8 1 2 and 5 8 pex and pex al pex tubing.

This is the best choice for new construction and areas receiving new slabs. This is about installing hydronic radiant floor heating in a slab floor system. The final step in preparing for our concrete slab is finished. Due to it s density and low conductivity concrete retains heat very well.

The size of the manifold must correspond to the number of circuits in your radiant heating system. While it was done as a new house was being built in my last house i poured a concrete floor on top of a wood framed floor system and could have put radiant heat in that as well. The most cost effective system for medium to larger homes is hydronic since the amount of power it would take to heat a whole home with electric would be substantial. There are three major types of radiant floor heating systems.

They can retain heat over time which is ideal for radiant under floor heating. What is hydronic radiant floor heating. There s two basic types of concrete floor heating hydronic and electric. Like sand concrete is an ideal carrier of radiant heat because of its inherent thermal mass.

The original and largely abandoned in the west method was used most notably in turkish baths and consisted of a raised floor to allow hot air underneath keeping the floor nice and warm. Water tubes or electric cables are easily embedded in concrete slabs. Concrete slabs have plenty of thermal mass.
