Installing radiant floor heating on concrete slab.

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 system works via pex pipe a small pump a water heater and a thermostat. These radiant floor heating systems can also be installed on top of a slab before the flooring goes down. Check out our video how to install radiant floor heat tubing in a slab on grade and read this page for a full description.

So even if there are no existing plans for the radiant floor heating or a snow melting system installing pex tubing in it may turn out to be a good decision. Radiant heating system design or installation mistakes that must be avoided. Tubing the water will circulate in tubing running beneath the floor in the concrete under wood floors or on a sub floor of wood precast concrete or slab on grade concrete. This is about installing hydronic radiant floor heating in a slab floor system.

Basic materials for radiant floor heat installation in a slab remember since you will only have 1 chance to pour the concrete slab you will only have 1 chance to put the pex tubing in it. From a radiant heating perspective it doesn t matter if the slab is actually at grade or is poured several feet below grade as part of a full foundation. Radiant heat can be an electrical heating element embedded into a very thin concrete overlay then tiled carpeted or have wood flooring installed over it. Quite simply concrete floor radiant heat is a system of pex tubes that carry hot water throughout a concrete floor or slab.
