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.

Radiant Floor Heating Applications

  • Quik Trak®
  • Using radiant panels called Quik Trak® on top of a plywood or concrete subfloor

  • Fast Trak™
  • Using knobbed mats called Fast Trak™ on top of a plywood or concrete subfloor


  • Fasten or Staple
  • Fastening the PEX tubing to wire mesh with wire ties or stapling the tubing to foam board before pouring a concrete slab

  • Joist Trak™
  • Installing the PEX tubing under the floor in between the joists with joist clips or Joist Trak™ heat-transfer plates.

  • Snow and Ice Melting
  • The radiant heating concept can also be used outdoors for snow and ice melting systems to keep driveways and walkways safe and free from snow and ice
