Why Install Floor Heating Under Hardwood?

Nailed hardwood floors can absolutely be heated—with the right system and thermostat settings. Our TempZone products are designed for this application.

Hardwood-Safe Heating TempZone systems deliver even, gentle heat. Keep the floor surface at or below 85°F to prevent drying, warping, or gapping—our smart thermostats handle this automatically.

Installs Under the Subfloor TempZone mats and cables embed in thinset on the subfloor, then hardwood is nailed down on top. Heat rises evenly through the wood.

Affordable to Operate Most zones cost just pennies per hour to heat. Use our operating cost calculator to estimate your monthly energy costs.

Silent & Draft-Free No noisy fans or forced-air drafts. Radiant heat rises evenly from the floor—consistent warmth without disturbing the air.

Clean & Energy Efficient No ductwork means no circulating dust or allergens. Radiant heat warms objects directly and is more efficient than forced-air systems.

Hardwood Floor Heating Customer Reviews

We take pride in providing both exceptional service and great products. But don't just take our word for it, check out what some of our customers have had to say.

Three years ago, I purchased electrical components to supply a low level of heat under a hardwod floor.

I personally installed the heating cable, added floor leveling compound, and then laid hardwood. I keep the temperature low around 73 deg F just to keep it from feeling cold. I followed the guidance of the company, and that which came with their products. The system has been working consistently since install.

Great experience working with WarmlyYours.

I had some special requirements due to the size and layout of the room but WarmlyYours came up with a solution that worked perfectly. Just installed the two mats and between the instructions that come with the product, and the excellent videos, it could not have gone in more smoothly. Highly recommended.

Works great with a third party thermostat.

I put these mats under bamboo hardwood flooring from *ome depo* in my 32' motorhome. Keeps it warm. After 9 months the GFCI I had it hooked up to (outlet) started tripping. After diagnosis ruled out under floor problems and I had already swapped out the GFCI outlet, I called for help. Troubleshooting help from OEM recommended a dedicated breaker with GFCI. Luckily it was a short run. Problem solved for under $100. Thanks.

I installed these Flex Rolls over a cork base and under bamboo floors.

They are wonderful! The ability to cut/turn the roll (without cutting the heating element/wire) made the install very easy and provided a great deal of flexibility. Ultimately, I was able to cover about 90% of the area of the master bedroom - the master bath had already been done... and this will make the whole winter wake up thing VERY nice. Ordering was easy - WarmlyYours was very helpful in providing product info, assisting with a suggested layout - and shipping was very fast. My only regret is that I didn't do this years ago.

Installing Heated Wood Flooring

Installing heated hardwood flooring can be done by the homeowners themselves or by a professional installer. WarmlyYours provides free design help to create a plan to install your heated wood floors, and, in most instances, orders are shipped the same day they are received, so you'll be able to appreciate the advantages of radiant heating systems sooner than you thought possible.

When choosing a system for heated hardwood floors there are a few considerations that will help make the project a success. Selecting wood flooring that will be the most compatible with radiant heating will help ensure many years of comfortable enjoyment of your home.

Nailed down hardwood floor cross-section with TempZone cable

Electric radiant heating can be installed quickly and easily under any hardwood floor. For hardwood floors, WarmlyYours recommends that our TempZone™ Floor Heating Cable is installed with fixing strips. The instructions for installation are straightforward, but there is also 24/7 technical support available if you need more assistance. Thin wood sleepers are laid down on the subfloor to create channels for laying out the heating cable and fixing strips, which are then embedded in self-leveling cement. The wood flooring is then nailed into the sleepers to complete the job.

Step-by-Step Installation

Step 1: Lay thin wood sleepers on the subfloor to create channels for the heating cable and fixing strips.
Step 2: Secure fixing strips in the sleeper channels per your SmartPlan layout.
Step 3: Lay out TempZone Floor Heating Cable in the channels, securing it to the fixing strips at proper spacing.
Step 4: Test the heating cable with an ohmmeter (test before, during, and after installation).
Step 5: Fill the channels with self-leveling cement, embedding the cable and creating a level surface.
Step 6: Once the self-leveling cement has cured, nail hardwood flooring into the sleepers.
Step 7: Wire the thermostat, set maximum floor temperature to 80–85°F, and enjoy!

How Much Does Hardwood Floor Heating Cost?

For nailed or glued-down hardwood, TempZone heating products cost C$6–C$17 per square foot depending on the system you choose. Flex Rolls cover large areas quickly, while cables with fixing strips offer more flexibility for irregular layouts. A 200 sq.ft. living room with about 140 heated square feet would cost between C$840 and C$2,380 for heating materials plus a thermostat (C$130–C$350).

Hardwood floors conduct radiant heat well, and the key is keeping the floor temperature below the manufacturer's recommended maximum (typically 80–85°F). Operating costs are modest—usually C$0.15–C$0.35 per hour for a living room zone. Use the calculator below to estimate your costs.

How Warm Are Heated Floor Systems?

Most wood flooring manufacturers recommend that the heated wood floor temperature be maintained between 80 to 85 degrees. This provides a warmer surface than an unheated floor, even in a well-heated house, but it is not so warm that it would feel hot to the touch.

The warmth of the floor is also dependent on the characteristics of the selected wood flooring. A thinner floor will typically be a few degrees warmer than a floor with thicker boards. Some wood species offer slightly better performance for radiant heating than others. The way that the boards are sawn can also make a difference. Quarter sawn boards are more expensive, but are more stable and less prone to swelling and shrinkage due to humidity changes. It has also been noted that darker woods will be less likely to show gaps and cracks. All of these factors should be considered in choosing the hardwood floor for your home.
