With the popularity of radiant floor heat and sales rising each year, more and more people are installing radiant floor heating systems.
Radiant Floor heat creates some questions when first starting, in this article series, we will explain the key points of radiant floor heat and give you the confidence to start including radiant floor heat in your projects.
What information is needed to get a project started?

What kinds of problems have occurred with radiant floor heat?

Final thoughts/ Summary
In a previous article, I explained the importance of an oxygen barrier tubing, and why hydronic floor tubing is a better option than electric mats. Hydronic radiant floor heat is simple to install once a designer has done his or her job correctly.
We also talked about why concrete contractors are getting more involved with hydronic radiant floor heat. So this should equip you with the confidence to talk radiant floor heat with your customers and add additional profit to your bottom line.
