How to Install Radiant Heat Under Hardwood Floors

Installing radiant heat under the hardwood floor is an easy task, but then, some measures should be considered for it to be a success. Failure to follow the right procedure would make everything come crashing down in failure.

We will give you a detailed format on how to install radiant heat under hardwood floors.

1. Get the tools needed to install the radiant heat under the hardwood floor. Tools like floor standing machine, notched trowel, woody putty, hammer, drill, pneumatic nails – 18-gauge, drill bit, chisel. These tools would be very necessary for the long run.

2. Tighten the heat transfer plate to the underpart of the old hardwood floor with a screw. Put in two similar layers of the plate in between each set of the floor joist.

3. Clamp the flexible PEX tube into the lines of the heat transfer plates. Then, bore a 5/8 inches hole into the floor joist to continue your tubing process.

4. Remember to cover the tubing and transfer plate with aluminum foil.

5. Apply open-cell foam insulation in the middle of the floor joist, covering the aluminum foil and insulating the tube.

6. Using a notched trowel, spread the flooring mastic all over the hardwood floor. To avoid the flooring mastic from drying out, work on each section at a time.

7. Set the new hardwood flooring onto the flooring mastic. Then, clamp it with a pneumatic nail – an 18-gauger filled with 1-inch nails.

8. Using a hammer and chisel, pry the floorboards together after fastening the nails.

9. Fill in the nail holes, advisably, with wood putty. Also, sand the floor till it is smooth.

10. Use, at the very least, three coats of polyurethane adhesive to the hardwood floor.

Things to Consider Before Installing Radiant Heat Under Hardwood Floors

Installing radiant heat in the home is a very welcomed development as it leaves the floor warm and cozy. But then, certain aspects require attention before you install radiant heat to avoid regrets in the long run.

Here are things to ask yourself if you plan to install radiant heat under hardwood floors.

But then, a need might arise for you to call on the professionals for help and advice at some point. And all this put together might be a bit costly. Be sure to know if you can afford the cost and procedures required in installing it in your home.

3. Would the Type of Hardwood I have Work with Radiant Heat?
