Installing Hardwood Floors over Radiant Heated Sub Floors
Installing Hardwood Floors over Radiant Heated Sub Floors
• Oak, Ash, Hickory, and Walnut species Engineered Hardwood products, > ½” thickness normally are approved for installation over radiant heated subfloors using either Adhered or Floating installation methods if applicable for the product.
• Nail or Staple Down installation methods are not recommended for Radiant Heated Sub Floors.
• Engineered product constructions thinner than ½” will require review by the Hardwood manufacture before installation; along with a location registration and an acknowledgment letter, verifying that the project is approved and warranted.
• Radiant Heating Systems used must be designed and controlled specifically for Hardwood flooring by the system manufacturer, and include an Outside Temperature Probe, and Surface Temperature Controls.
• The end consumer should be aware that minor gaping between wood planks during the heating season is a normal occurrence with hardwood flooring installed over radiant heated subfloors.
• Proper humidity controls within the home or business will help to minimize the natural wood reaction to seasonally changing climate conditions.
• Indoor climate should be maintained between 60-80° F and a relative humidity range of 35%-65%.
Adhere to the following guidelines for a successful installation :
• Newly installed water type radiant heated flooring systems should be in operational mode with the temperature set between 64° -72°F, for a minimum of 4 weeks to insure that all sub floor moisture has properly dried.
• Older water type radiant floor heat systems should be fully pressure tested, properly maintained, and set to a minimum of 64°F, for at least 4 days before flooring delivery; acclimation, or installation processes may begin.
• All radiant heating systems must be set to room temp. (A minimum of 64°F), for at least 4 days before flooring delivery; acclimation, or installation processes may begin.
• Always check wood sub floors to insure that the moisture content is less than 14% using an accurate wood moisture meter.
• Concrete sub floors must register “dry”, using a reliable concrete moisture meter.
• The pH level of concrete sub floors should register between 6 and 9, on a fourteen point pH scale.
• Sub floors must fully comply with these “dry” requirements before proceeding with the delivery, acclimation, or installation of the wood flooring at the job site.
• Regulate the job site to insure that the relative humidity is between 35% and 65%, and that temperature is between 60° and 80° F, throughout the flooring delivery, acclimation, installation and any required curing processes.
• Deliver and acclimate the engineered hardwood flooring, for at least 48 hours before installation begins.
• Install the hardwood flooring according to the instructions that pertain to the product.
• After completing the installation, do not change the radiant heat setting for 48 hrs.
• Throughout the life of the installation, 3 to 5 degree daily increments must be used when adjusting system temperature for either upward or lower adjustments; so that the hardwood flooring can adjust to the temperature changes in a gradual manner.
• Never raise the flooring surface temperature setting above 85 degrees Fahrenheit

Howdie. Nice post. Thanks for taking the time to post about your view with the planet.
You actually make it seem so easy with your presentation but I find this topic to be really something that I think I would never understand. It seems too complex and extremely broad for me. I’m looking forward for your next post, I will try to get the hang of it!
I really enjoy this blog. I wish I could come here everyday\all day.
Great overview to installing wood flooring, people always seem to forget to make sure they acclimatise the wood first and a lot of people still don’t make sure the subfloor is completely flat.
Cheers, That was a great post, I really enjoyed reading your blog. I am going to save it and will make sure to check weekly.
What a write!! Very informative also easy to understand. Looking for more such posts!! Do you have a twitter?
I recommended it on digg. The only thing that it’s missing is a bit of speed, the pictures are appearing slowly. Anyway thank you for this blog.
I have recently been doing research to better understand the process of hardwood flooring installation. I found the post here to be very enlightening because I didn’t realize the importance of temperature a acclamation for the wood. I’m not currently an installer, but a webmaster for Flooring Construction Group located in Indianapolis, IN.
The more I read articles and learn what it takes to do hardwood flooring the more I can understand my job, while at the same time becoming more educated in the industry. I will show my boss this article and converse with him about all the different temperatures. He has been laying hardwood floors for more than 30 years. Great Post…
Great blog – some good information and well presented.
pretty useful information men, congratulations,
I am the first time on this site and am really enthusiastic about and so many good articles. I think it’s just very good.
I’ve been pondering about this alot… it sure raises a few questions..
You have tested it and writing form your personal experience or you find some information online?
I will say this is an extremely written article.
In reply to scotts.
You are absolutely right but that has nothing to do with the topic
