Installing an Underfloor Heating System with Hardwood Floors
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.

Install Your Underfloor Heating System Faster with a PEX Gun 
PEX tubing distributes heat in a radiant underfloor heating system. Installing PEX tubing can be done efficiently with a pneumatic nail gun, also known as a PEX gun.
A PEX gun shoots safe, strong polyethylene clips that fit perfectly without compressing or damaging PEX tubing.
A PEX gun is by far the quickest and most affordable way to install PEX tubing for your underfloor heating system.
Krell Distributing can provide you with an affordable PEX gun with all of the tools and materials you'll need to complete your radiant floor heating installation.

Reflective Foil Insulation for an Underfloor Heating System
Reflective bubble insulation is used under PEX tubing in underfloor heating system installations. Krell Distributing Company can provide the reflective foil insulation you need for your underfloor heating system. We offer this reflective foil insulation in a 16" x 125" roll.
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.
