Retrofit Radiant Floor Heating On Concrete Slab

A slab on grade is defined as any concrete slab poured over excavated soil.

These radiant floor heating systems can also be installed on top of a slab before the flooring goes down. Retrofitting a concrete floor with radiant heat while most radiant heating systems are in floor installations and go down before the floor is placed some electric systems are available in mats or loose wire systems as thin as 1 16 inch that can be affixed to existing concrete or wood subfloors and then covered with a thin set cement or gypsum.

I am planning on installing a hydronic radiant floor heating in my basement on top of existing concrete slab. 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. The major requirement is being able to add another layer to the top of the floor. I don t experience the warm floors much the heat load is so low that the floor doesn t stay on too long in order to satisfy the heat call my house here in new jersey design temperature.

The toh project house has a manifold in the basement where all the tubing originates and returns. January 2018 in radiant heating. For concrete floor radiant heating systems the warm water tubing or electric heating elements can either be embedded within the slab on grade anywhere from the bottom of the slab to within 2 inches of the surface depending on the design and installation technique or fastened to the top of a concrete subfloor and then covered with an overlay. 14f has low heat load too.

Quite simply concrete floor radiant heat is a system of pex tubes that carry hot water throughout a concrete floor or slab. Retrofitting radiant heating over a concrete floor is the hardest to do but it is possible. A radiant floor heating system needs a hot water supply a connection between the tubing and the plumbing and a pump to move the water from one to the other. I have outdoor reset so the supply temperature can be quite low to the radiant slab floor.
