Radiant Floor Heating

Lyle in MI


I have a concrete slab foundation and want to install laminate flooring. Is there a way for me to install something to heat the slab under the flooring without tearing up the concrete?

There are several manufacturers out there who have systems that are placed directly on top of the concrete slab. Some look like wire fencing that you just roll out over the floor. I don’t particularly like them, because I don’t think they’re very energy efficient. Don’t get me wrong. I’m sure there are some good radiant systems out there, but you need to do your homework to find out how much electricity they use over any given period of time. From what I’ve read, though, the hydronic types have the greater blessings of the EPA studies. Again, there are several manufacturers. One that I can personally vouch for is from Uponor. You put their plywood subfloor down first. It has pre-cut “S” shaped grooves in it just the right width for plastic tubing. The tubing connects to a separate water heater & manifold that will keep the hot water circulating through the tubing. Once you install the system, you can put your new flooring right on top.

If you already have your laminate installed, you're out of luck. However....never say never. Check out some of the radiant heat throw rugs! It's not as good as having the system under the floor, but it's a viable alternative!
