There s two basic types of concrete floor heating hydronic and electric.
Hydronic radiant floor heating concrete slab.
This is about installing hydronic radiant floor heating in a slab floor system.
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.
Embedding your radiant heating system into a concrete slab is one of the most cost effective ways to install it and most energy efficient being that concrete is a great thermal mass.
See the pdf multipage spec sheet that is linked on the u fin page of our site.
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.
Heating up the mass of concrete is not necessarily a good thing when you want the entire surface floor to be warmed.
The thermofin u heat transfer plates are easier to install if the fins are down against the subfloor and plywood sleepers on the fins.
This is the best choice for new construction and areas receiving new slabs.
