Finding The Right Natural Flagstone for Hydronic Heat
by Pete Sutsos

I was wondering if you could answer a technical question for me about flagstone? We are building a home that is going to be using hydronic heat (in floor radiant) and are planning on using flagstone as an overlay flooring material over the concrete floor that is going to be poured to support the hydronic heat tubing.
We want to use an irregular style neutral color (brown or sandy color) natural flagstone. Can you make some recommendations of what would be the best to use for our application? We want the floor surface to be as smooth as possible and are going to have a seal coat placed over the top.
Thanking you in advance for your assistance and direction.
