Installing an Underfloor Heating System with Hardwood Floors

underfloor heating system for heated hardwood floors by krell distributing company
With this type of DIY radiant floor heating, the heat source is located directly beneath the hardwood floor. Underfloor heating systems can be installed with hardwood floors if the proper precautions are taken.

It's also important to understand what type of wood flooring to use. 

Laminated/Engineered Wood Flooring offers more dimensional stability than solid wood flooring.

American Cherry wood, American walnut wood, Mesquite and Teak offer inherent dimensional stability that is suitable for underfloor heating systems.

Quartersawn or Rift Sawn Wood Flooring offers greater dimensional stability compared to plainsawn wood flooring. 

Krell Distributing recommends that all seams are taped during the installation process to ensure the barrier is tight. To protect the barrier from rips, laying a 1/16" (1.5625mm) thick foam sheeting over the vapor barrier may be advisable.

Aluminum Heat Transfer Plates are an Important Part of an Underfloor Heating System

Aluminum heat transfer plates can be used to attach PEX tubing to the underside of the wooden subfloor, in conjunction with the foil insulation to enhance the heat transfer between the PEX tubing and the flooring.

The aluminum transfer plates are useful in areas of high heat loss (entryways, outside walls, or areas that may have carpet installed on the finished floor).

Plates are 4" wide x 20" long. Consult a Krell representative to assist you in determining the number of plates require and spacing between the plates for your specific project.
