How Does Radiant Floor Heating Work?
The main components in a radiant floor heating system include a heat source, pumps, manifolds, tubing and controls.
There are many heat source options for a radiant floor heating system, including boilers, hot-water heaters, geothermal and solar. The heated water from the heat source travels to a manifold where it disperses into tubing “loops” laid in the floor.
The tubing in a hydronic radiant floor heating system is a flexible, plastic piping product called PEX (an acronym for crosslinked polyethylene). The PEX tubing carries the heated water from the manifold to the floor and then back to the return side of the manifold so it can return to the heat source for reheating.
