How to Install Radiant Floor Heating in Your Home

By: Danny Lipford

Radiant flooring heating systems are an energy efficient way to gently warm a room by heating the floor. This system from Uponor uses hot water piped through a closed loop of flexible PEX plastic tubing.

First, the floor system—consisting of machined strips of plywood with a dovetailed groove to receive the plastic tubing—was screwed down to the subfloor. The curved returns at each end of the room allow one continuous piece of tubing to loop back and forth across the floor without any joints.

Once the track was in place, a bead of silicone caulking was applied to the bottom of the groove, and the plastic tubing hammered into it with a rubber mallet. A pump is used to circulate hot water through the tubing from a 2½ gallon hot water tank to warm the floor.

    Should the in floor heat be a closed system, or is it ok if it is run off of the waterheater for the house?

    In the video of installing the radiant floor heating system, who is the manufacturer of the panels that are laid on the subfloor to hold the flex tubing? Do they also sell the flex tubing and the water manifolds?

    Hi Vernon,
    In the article under our video on How to Fix Squeaks Under Carpeting is a link to the company that makes the squeaky floor repair kit. You can buy it online at their site. Good luck with your project!
