Best Types of Flooring To Be Installed Over Radiant Heating

What is the Best Flooring for Radiant Heat Systems?

Ceramic or porcelain tile is the ideal flooring type for an underfloor radiant heat system. Tile is the most effective type of floor covering to use with radiant floor heating, according to the US Department of Energy. Tile is thin, durable, and conducts heat really well, increasing energy efficiency.

Radiant heat has many benefits. Walking on heated floors in winter is very cozy. The dog will love laying on it. And radiant heat can be very economical.

If you’re considering the installation of a radiant heat system, some flooring options work better than others. Here are the top 4 flooring options for use over radiant heat.


Porcelain and ceramic tile are great conductors of heat, so your home will get the full benefit of the radiant heating system. In addition, tile flooring will not expand as it warms or contract as it cools. Such expansion and contraction can cause cracking. That’s not a problem with tile.


Laminate flooring replicates the look of solid hardwood flooring or tile flooring without the expense. It also does a great job over radiant heat. The laminate material is built up with layers of wood that run in opposite directions. This creates a more stable material than solid hardwood. The laminate won’t expand and contract, in other words, like solid hardwood flooring wood.


Like laminate, it is produced in layers, so it has a more stable base that won’t react to the heating and cooling process. The top layer, or wear layer, is solid wood and comes in all the same varieties that you’ll find with other solid hardwood flooring. Engineered flooring even comes in bamboo. It looks great, wears great and warms great.


Granite, travertine, sandstone and other natural stone flooring types conduct heat wonderfully. You might think of stone as cold, but not when it has got warm water flowing beneath it. If you never thought you’d like to walk on stone flooring bare-footed in January, you never considered radiant heat!


Luxury vinyl flooring, in particular wood look vinyl plank flooring, is incredibly popular and with the introduction of higher quality rigid core technology most vinyl plank and tile can now be used with underfloor heating.

Be sure to to check the installation requirements for each individual product as the warranty will often state the maximum temperature that the vinyl plank has been certified to work with.


What about the opposite question?  What type of flooring should not be installed over radiant heat?  Carpet has insulation value, so it will prevent some of the heat from transferring through into your home. You can use a few area rugs over the flooring, but avoid large rugs or wall-to-wall carpeting.

Vinyl flooring is not a good choice either. The heat may discolor the vinyl or cause the off-gassing of chemicals. Finally, solid hardwood flooring will swell and shrink with the heating/cooling process, especially in homes that use a humidifier during winter. You don’t want to invest in pricey hardwood flooring only to have it cup, buckle, crown and crack.

If you’re planning to install comfortable, efficient radiant heat, your best choices for use with radiant heating are tile flooring, laminate flooring, engineered flooring and natural stone flooring.

    Hello Pros
    Can radiant floor matting be laid over a existing vinyl tiled floor?

    We have laminate flooring and radiant heat, however it is not warm to touch. Our ceramic tile flooring is warm when heating up but cools quickly. I thought we would have toasty feet all winter but we do not. We used bubbly insulation and fiber glass insulation in the rafter area between basement and 1st floor to try to help improve our heating.

    hello pros,

    can steel sheets be used for flooring with floor heating? steel wouldn’t be in direct contact with the floor, it will be raised to 2cm creating a void underneath it above the surface of the radiant floor.

    We are building a new home and have the slab already done with the radiant in floor heat. We are wanting to install the new luxury vinyl plank floors. It is safe to do that. We do not want ceramic or carpet.

    We have radiant heat with ceramic tile throughout the entire downstairs of our home. We are also on a slab. My question is / can we put stick and peel tiles directly on top of this flooring? I say no, but someone I know says yes. Can you please comment ASAP.
