How You Too Can Have Radiant Heating Under Hardwood Flooring

Radiant, in-floor heating is a great addition to your home. It helps to serve as a secondary (or primary in some regions) source of heat, is better for allergy sufferers than forced air systems, improves energy efficiency and best of all gives, you a warm fuzzy feeling on your toes. Radiant heating is generally very simple to install, but some consideration needs to be made about the type of flooring going over top of the tubes or wiring that conduct the heat.

Carpet is pretty much out of the question regarding radiant heat. Stone is a great conductor of heat, but will also cost you a pretty penny. Tile is one of the best flooring types for radiant heating, but it doesn't exactly convey a look of elegance. It's for these reasons that solid hardwood flooring is considered the premier option for homes with radiant heating.

Adding radiant heating under solid hardwood flooring not only gives it a warm look, but literally a warm feel as well. There are some misconceptions about what kind of solid hardwood that should be used in conjunction with radiant underfloor heat or if it should be used at all. Here's the breakdown on the different wood flooring types and how they work with radiant floor heating.

Engineered Flooring Over Solid Hardwood

The choice of engineered wood flooring over solid hardwood flooring isn't really a choice at all because a majority of industry manufacturers do not warranty their 3/4” solid hardwood flooring for installation over radiant flooring. This isn't saying that solid hardwood flooring cannot be installed over radiant heating, but you take a big risk with your investment when you do. Quarter-sawn (vertical grain instead of horizontal) solid hardwood will provide the best results but it's still a bold move.

Floating Installation Over Nailed Down

Another conundrum when determining what type of solid hardwood flooring to use with radiant heat is installation type. Thicker hardwood floors are usually recommended to be nailed down, but doing so sometimes causes your floor to buckle as it cannot expand and contract with weather changes. Thinner hardwood flooring not only have limited durability, but it can also warp over the radiant heating.

  2. Make sure the radiant heating is properly installed so the surface temperature never exceeds 85°.
  3. Buy a hygrometer to measure relative indoor humidity and make sure it's between 40% - 50%
